Description

Background

Along the axial direction of the output shaft, the thrust bearing disc is positioned at the side of the thrust part, and the thrust block is positioned between the thrust bearing disc and the thrust part. The number of the thrust blocks is multiple. The plurality of thrust blocks are disposed at intervals in a circumferential direction around an axis of the output shaft.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present application. It will be apparent that embodiments of the application may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present application are described in detail below, however, the present application may have other embodiments in addition to these detailed descriptions.
The application provides a thrust bearing. Thrust bearings are used in ships for transmitting torque. The thrust bearing adopts a self-balancing structure, and the bearing of each thrust block 160 tends to be uniform through the lever principle.
Referring to fig. 1 to 13, the thrust bearing includes a housing 110 and an output shaft 120. The housing 110 includes an upper housing 111 and a lower housing 112. The lower end of the upper case 111 is connected to the upper end of the lower case 112. The housing 110 has an inner cavity and a shaft hole communicating with the inner cavity. The output shaft 120 penetrates through the shaft hole to pass through the internal cavity of the housing 110.
The output shaft 120 may be connected to the stern shaft end of the vessel for transmitting torque. The output shaft 120 has a thrust portion 121. The thrust portion 121 is configured as an annular flange formed by extending and protruding a portion of the outer peripheral surface of the output shaft 120 outward in the radial direction of the output shaft 120.
The thrust bearing further includes a thrust member. The thrust member includes a thrust seat 130. The bearing seat 130 is a ring-shaped structure with a closed circumference. The bearing seat 130 is sleeved on the output shaft 120. The thrust bearing 130 is located laterally of the thrust portion 121 along the axial direction of the output shaft 120. The socket 130 is connected to the housing 110. The thrust bearing 130 has a force receiving surface 139 facing the thrust portion 121.
The thrust member further includes a first counterbalance 140 and a thrust block assembly 150. The first weight 140 is located between the thrust portion 121 and the force receiving surface 139 in the axial direction of the output shaft 120. The first balance weight 140 is plural. The plurality of first weights 140 are disposed at intervals in the circumferential direction about the axis of the output shaft 120. As shown in fig. 7, 8 and 13, the first balance weight 140 includes a first balance body 141, an adjusting portion 143 and a first overlapping portion 142.
The end portion of the first balance body 141 extends to protrude in the circumferential direction around the axis of the output shaft 120 to constitute a first overlap portion 142. One end of the first balance body 141 is provided with one first overlap portion 142 in a circumferential direction around the axis of the output shaft 120, and the other end of the first balance body 141 is provided with another first overlap portion 142. The portion of the surface of the first balance body 141 remote from the thrust portion 121 extends away from the thrust portion 121 to protrude to constitute an adjustment portion 143. The adjustment portion 143 is located at a substantially middle position of the first balance body 141 in a circumferential direction around the axis of the output shaft 120. The adjustment portion 143 extends from one end to the other end of the first balance body 141 in the radial direction of the output shaft 120.
The end surface of the adjustment portion 143 remote from the thrust portion 121 is configured in a first arc-shaped structure. The outer end of the first arc-shaped structure, which is far from the center of the first arc-shaped structure, is used for abutting against the stress surface 139. Thus, the adjustment portion 143 is in line contact with the force receiving surface 139.
The thrust block assembly 150 is connected to the thrust block 130. In the axial direction of the output shaft 120, the thrust block assembly 150 is located between the bearing surface 139 and the thrust portion 121. The thrust block assembly 150 is provided with second overlap portions 172 at both ends in the circumferential direction about the axis of the output shaft 120. The second overlap portion 172 is located on a side of the first overlap portion 142 near the thrust portion 121.
The pad assembly 150 is plural. The plurality of thrust block assemblies 150 are spaced apart in a circumferential direction about the axis of the output shaft 120. Along the circumferential direction around the axis of the output shaft 120, one pad assembly 150 is provided at the interval between the two first weights 140, and one first weight 140 is provided at the interval between the two pad assemblies 150.
One end of the thrust block assembly 150 adjacent to the thrust portion 121 is located on a side of the first weight 140 adjacent to the thrust portion 121. The two second overlap portions 172 of the adjacent two pad assemblies 150, which are close to each other, are respectively used to overlap to the two first overlap portions 142 of the first balance weight 140 in the circumferential direction about the axis of the output shaft 120.
In this way, when the output shaft 120 receives an axial force parallel to the axial direction of the output shaft 120 (for example, an axial force transmitted from the propeller to the output shaft 120 through the shafting), the axial force is transmitted to the housing 110 and finally to the hull through the thrust portion 121, the thrust block assembly 150, the first weight 140, and the thrust bearing 130 in this order, and the ship is thereby moved forward or backward.
In this process, please refer to fig. 13. In fig. 13, the up-down direction is the axial direction of the output shaft 120. The width direction is a portion in the circumferential direction about the axis of the output shaft 120. The thrust portion 121 acts on the thrust block assembly 150 such that the second overlap portion 172 acts on the first overlap portion 142, thereby rotating the first balance weight 140 about the center of the first arc-shaped structure of the adjustment portion 143. Thus, the first plurality of weights 140 and the first plurality of pad assemblies 150 form a self-balancing structure, and adjacent pad assemblies 150 and first plurality of weights 140 are coupled to form a lever structure such that the load (force of the thrust portion received) of each pad assembly 150 is substantially the same.
In this embodiment, the thrust block assembly 150 and the first balance block 140 are disposed, where the output shaft 120 receives an axial force, the first balance block 140 and the thrust block assembly 150 integrally form a self-balancing structure, and the adjacent thrust block assemblies 150 and the first balance block 140 are linked to form a lever structure, so that the bearing of each thrust block assembly 150 is approximately the same, the possibility that individual thrust blocks wear earlier than other thrust blocks is reduced, and the service life of the thrust bearing is prolonged.
Preferably, as shown in fig. 7, 8 and 13, a portion of the first balance body 141 extends and protrudes to a side of the first overlap portion 142 near the thrust portion 121 to form a first step portion 146. The first step 146 has a first step side 145. The first step side 145 is inclined to the axial direction of the output shaft 120. The first step 146 gradually decreases in size from an end away from the thrust portion 121 toward an end close to the thrust portion 121. Thus, the strength of the first weight 140 is high.
Preferably, referring to fig. 7, 8, and 11 to 13, the adjustment portion 143 is provided with a balance positioning hole 144. The bottom wall 131 of the thrust plate has thrust holes. The thrust bearing also includes fasteners (e.g., screws). The shaft portion of the fastener may extend into the balance positioning hole 144 after passing through the thrust bearing hole. The outer diameter of the shaft portion of the fastener is less than the inner diameter dimension of the balance positioning hole 144. In this way, the first weight 140 can be prevented from rotating about the output shaft 120.
Preferably, referring to fig. 3, 4, 11 and 12, the socket 130 has a bottom wall 131, an outer annular wall 132 and an inner annular wall 133. The outer annular wall 132 is sleeved on the outer periphery of the inner annular wall 133, and a space exists between the outer annular wall 132 and the inner annular wall 133. The outer annular wall 132 and the inner annular wall 133 are disposed substantially coaxially. The bottom wall 131 is located on the same side of the outer annular wall 132 and the inner annular wall 133, and connects the outer annular wall 132 and the inner annular wall 133. Thus, the bottom wall 131, the outer annular wall 132 and the inner annular wall 133 form an annular recess 134. The annular recess 134 is a circumferentially closed annular structure. The inner annular wall 133 is sleeved on the output shaft 120. The annular groove 134 opens toward the thrust portion 121. The surface of the bottom wall 131 facing the thrust portion 121 is a force receiving surface 139.
The first weight 140 is located within the annular recess 134. The size of the first balance weight 140 is slightly smaller than the size of the annular groove 134 in the radial direction of the annular groove 134. The thrust block assembly 150 is connected to the outer annular wall 132 of the annular groove 134. Thus, the structure of the thrust bearing part is simple.
Referring to fig. 3-6 and 9-13, the thrust block assembly 150 includes a thrust block 160 and a second weight 170. The second weight 170 has a second weight body 171 and a second overlap 172. The end portion of the second balance body 171 extends to protrude in the circumferential direction around the axis of the output shaft 120 to constitute a second overlap portion 172. One end of the second balance body 171 is provided with one second overlap portion 172 in the circumferential direction around the axis of the output shaft 120, and the other end of the second balance body 171 is provided with another second overlap portion 172. Thereby, the structure of the second weight 170 is simple.
As shown in fig. 5 and 6, the thrust block 160 may have a fan-shaped structure. The thrust block 160 is connected to the outer annular wall 132. The second weight 170 is located on a side of the thrust block 160 remote from the thrust portion 121 in the axial direction of the output shaft 120. One of the thrust block 160 and the second balance block 170 is provided with a first contact portion protruding toward the other, and the other is provided with a second contact portion protruding toward one. The end of at least one of the first contact portion and the second contact portion configures a second arcuate structure. The first contact portion and the second contact portion are contacted by the second arc-shaped structure, so that the first contact portion is used for point contact with the second contact portion.
In this way, when the output shaft 120 receives an axial force parallel to the axial direction of the output shaft 120, the force is transmitted to the housing 110 and finally to the hull via the thrust portion 121, the thrust block 160, the second weight 170, the first weight 140, and the thrust bearing 130 in this order, and the ship is caused to advance or retract. Wherein axial force may be transferred between the thrust block 160 and the second weight 170 through contact of the first contact portion and the second contact portion.
In this process, the thrust portion 121 acts on the thrust piece 160 such that the thrust piece 160 acts on the second balance piece 170, and the second overlap portion 172 acts on the first overlap portion 142. Thus, the second weight 170 can be inclined with respect to the thrust block 160, and the bearing capacity of the thrust block 160 can be improved.
Specifically, the thrust assembly further includes a thrust sensor 180. The thrust sensor 180 is connected to the second weight 170 and extends toward the thrust block 160 to protrude beyond the second weight 170 to constitute a first contact portion. The head of the thrust sensor 180 on the side of the second weight 170 near the thrust block 160 is configured in a second arc-shaped structure.
The thrust assembly also includes a cushion head 190. The material strength and hardness of pad head 190 are greater than the material strength and hardness of thrust block 160, respectively. The size of pad head 190 is smaller than the size of thrust block 160. The pad 190 is connected to the pad 160 and extends toward the second balance mass 170 to protrude the pad 160 to constitute a second contact portion. Thus, the cushion head 190 has high strength and good wear resistance, and can protect the push block. Further, a thrust signal indicating the magnitude of the axial force may be acquired by the thrust sensor 180.
Further preferably, the second balance weight 170 has a sensor mounting hole 173 and a balance wire hole 176. The surface of the bottom wall 131 facing away from the thrust portion 121 is recessed toward the thrust portion 121 to form a cable groove 138, and has a push-wire receiving hole 137 at the cable groove 138. The thrust assembly is located at the cable trough 138 in a circumferential direction about the axis of the output shaft 120. The positions of the thrust line holes 137 and the positions of the balance line holes 176 are correspondingly set. The sensor mounting hole 173, the balance wire hole 176 and the push wire hole 137 are through holes.
In the circumferential direction about the axis of the output shaft 120, the sensor mounting hole 173 is located in the middle of the second balance mass 170, and the balance line hole 176 is located in the middle of the second balance mass 170. The sensor mounting hole 173 and the balance wire hole 176 are provided at intervals. The push force sensor 180 is provided through the sensor mounting hole 173. The thrust sensor 180 is screwed to the wall of the sensor mounting hole 173. The cable connected to the push force sensor 180 may pass through the push wire hole 137, then pass through the balance wire hole 176, and then extend through the cable slot 138. Thus, the thrust sensor 180 can be mounted from the side of the second weight 170 away from the thrust block 160, facilitating the mounting of the thrust sensor 180.
Further preferably, as shown in fig. 9 and 10, a portion of the second balance body 171 extends to protrude to a side of the second overlap portion 172 away from the thrust portion 121 to constitute a second stepped portion 178. The second step 178 has a second step side 175. The second step side 175 is inclined to the axial direction of the output shaft 120. The second stepped portion 178 gradually increases in size from an end distant from the thrust portion 121 toward an end close to the thrust portion 121. Thus, the strength of the second weight 170 is large.
The end of the second balance mass 170, which is remote from the axis of the output shaft 120, is provided with a balance gap 174 in the radial direction of the output shaft 120. The opening of the balancing notch 174 is remote from the axis of the output shaft 120. The outer annular wall 132 is provided with a bearing positioning hole 122. The bearing positioning hole 122 is a through hole. The position of the bearing positioning hole 122 and the position of the balance notch 174 are correspondingly arranged. The fastener extends into the balance gap 174 after passing through the bearing positioning hole 122. In this way, rotation of the second counterweight 170 relative to the socket 130 about the axis of the output shaft 120 can be avoided.
The edge of the outer annular wall 132 adjacent the thrust portion 121 is provided with a locating groove 136. The thrust block 160 includes a thrust body 161. The portion of the surface of the thrust body 161 near the bottom wall 131 extends and protrudes toward the bottom wall 131 to constitute a positioning projection 162. The positioning protrusion 162 is disposed in the positioning groove 136. In this way, thrust body 161 overlaps to the edge of outer annular wall 132 near thrust portion 121. In this way, the thrust piece 160 can be prevented from rotating about the axis of the output shaft 120.
The surface of thrust body 161 adjacent thrust portion 121 includes a first surface 164 and a second surface 165. The first surface 164 and the second surface 165 intersect. The first surface 164 is inclined to the second surface 165. The first surface 164 is for being parallel to the side of the thrust portion 121. The second surface 165 is formed by extending one end of the first surface 164 obliquely toward the thrust portion 121. In this way, it is convenient to quickly form a lubricating oil film on the surface of the thrust piece 160 near the thrust portion 121.
The outer circumferential ring of the socket 130 is provided with a stop notch 135. The thrust bearing also includes a stop 191. The stopper 191 may be coupled to the housing 110 by a fastener. Part of the stop 191 extends into the stop notch 135. Thus, the thrust bearing 130 can be prevented from rotating about the output shaft 120.
Preferably, the thrust member and the thrust portion 121 are located within the housing 110. The thrust members include a first thrust member 192 and a second thrust member 193. Along the axial direction of the output shaft 120, the first thrust member 192 is located on one side of the thrust portion 121, and the second thrust member 193 is located on the other side of the thrust portion 121. Thereby, the thrust bearing is able to withstand two different axial forces in opposite directions.
In the axial direction of the output shaft 120, the interval between the thrust portion 121 and the force receiving surface 139 satisfies the self-balancing structure formed by the first balance block 140, the second balance block 170 and the thrust block 160, so that the play of the first balance block 140, the second balance block 170 and the thrust block 160 in the axial direction of the output shaft 120 can be reduced as much as possible.
Preferably, as shown in fig. 4, the thrust member further includes an adjustment ring 194. The adjustment ring 194 is attached to the side of the bottom wall 131 remote from the force bearing surface 139. The adjustment ring 194 is removably connected to the thrust bearing 130 by fasteners. In the axial direction of the output shaft 120, a surface of the adjustment ring 194 remote from the thrust portion 121 may abut against the housing 110. The adjustment ring 194 may have a variety of gauges. The thickness of the adjustment ring 194 varies from gauge to gauge. Thus, a different adjustment ring 194 may be used to adjust the gap between the thrust member and the thrust portion 121.
As shown in FIG. 2, the thrust bearing further includes a radial bearing assembly 195. The radial bearing assembly 195 may comprise a bearing shell. The radial bearing assembly 195 is disposed between the outer circumferential surface of the output shaft 120 and the housing 110. Thus, the radial bearing assembly 195 may counteract the radial force of the output shaft 120.
With continued reference to FIG. 2, the thrust bearing further includes a seal assembly 123. The seal assembly 123 includes an oil seal. A seal assembly 123 is provided between the housing 110 and the output shaft 120 to seal a gap between the housing 110 and the output shaft 120. The sealing assembly 123 is located at the outer edge of the shaft hole of the housing 110.
As shown in fig. 1 and 2, the thrust bearing further includes a controller, a torque signal conversion box 201, a thrust signal conversion box 196, a torque measurement ring 197, a torque signal acquisition box 200, a tubing assembly 198, and a sensor assembly 199.
The torque measuring ring 197 is fitted around the outer periphery of the output shaft 120. The torque measurement ring 197 may be coupled to the output shaft 120 by fasteners to collect torque signals indicative of the magnitude of the torque transmitted by the output shaft 120 in real time. The torque measuring ring 197 and the torque signal collection box 200 are connected by a radio connection to transmit a torque signal. The torque signal collection box 200 is connected to the top end of the upper housing 111 and is located above the upper housing 111. The torque signal collection box 200 and the torque signal conversion box 201 are electrically connected by wireless means or by a cable to transmit a torque signal. The torque signal acquisition box 200 can transmit the torque signal it acquires to the torque signal conversion box 201.
The torque signal conversion box 201 is located above the upper case 111 and is connected to the upper case 111. The torque signal conversion box 201 and the controller may be electrically connected by wireless to transmit a torque signal to the controller.
The sensor assembly 199 includes a temperature sensor and a pressure sensor. The sensor assembly 199 is disposed on the upper housing 111, the lower housing 112, the radial bearing assembly 195, the first thrust member 192 and the second thrust member 193 for collecting the working signal in real time. The operating signals include temperature signals and pressure signals of the lubricating oil in the upper and lower housings 111 and 112, and temperature signals of the radial bearing assembly 195, the first and second thrust members 192 and 193. The sensor assembly 199 and the thrust signal conversion box 196 are electrically connected by wireless means or by a cable to transmit the operation signals collected thereby to the thrust signal conversion box 196.
The thrust signal conversion box 196 is located above the upper housing 111 and is connected to the upper housing 111. The thrust sensor 180 is connected to the thrust signal conversion box 196 by a cable to transmit the thrust signal collected by the thrust sensor 180. The thrust signal conversion box 196 and the controller may be electrically connected by wireless means to transmit thrust signals and operating signals to the controller.
The pipe assembly 198 is disposed in the lower housing 112, the upper housing 111 and the sealing assembly 123 for circulating the lubricating oil to form a lubrication cycle.
The application also provides a ship. The vessel comprises the thrust bearing described above.
In this embodiment, the ship includes the thrust bearing, where the thrust block assembly 150 and the first balance block 140 are disposed, and when the output shaft 120 receives an axial force, the first balance block 140 and the thrust block assembly 150 integrally form a self-balancing structure, and the adjacent thrust block assemblies 150 and the first balance block 140 are linked to form a lever structure, so that the bearing of each thrust block assembly 150 is approximately the same, and thus the possibility that individual thrust blocks wear earlier than other thrust blocks is reduced, and the service life of the thrust bearing is prolonged.
