Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating body device having a rotating body such as a gear, a roller and a pulley, and constituting a mechanism for transmitting a rotating force. The present invention relates to a rotating device that rotates by sliding on a member.

[0002]

2. Description of the Related Art In a rotating device in which a gear is rotatably supported, when the end surface of the gear and the end surface of a bearing supporting a rotating shaft to which the gear is mounted slide, both materials are made of resin. Then, there is a risk of fusing each other, abrasion and abnormal noise. Therefore, in the conventional rotating body device, a member such as a thin spacer made of a low-friction material is sandwiched between the two to prevent the portions of the same or similar material from sliding with each other.

Further, in a conventional rotating body device, as shown in FIG. 10, a flange portion 107 is formed on an end surface of one gear (a driven gear in the figure) 103 meshing with each other, and the other gear (a figure in the figure). (Relay gear) 102 with the flange 1
07, the relay gear 1 has a simple structure.
In some cases, dropout of the 02 is prevented. Even in such a structure, the flange 107 of the driven gear 103
When both the end face of the relay gear 102 and the end face of the relay gear 102 are made of resin, there is a possibility that they may be fused to each other, or wear or noise may be generated. A member such as a collar or a sleeve is sandwiched between the members to prevent the same or similar material from sliding.

Further, in order to fix the position of the gear in the rotating body device in the axial direction, the boss of the gear is extended in the axial direction, and the end face of the extended boss is formed on the flange formed on the adjacent gear. In some cases, the function of the above-described member such as the spacer, the collar, or the sleeve is realized at the extended portion of the boss portion by making contact.

For example, Japanese Patent Application Laid-Open No. 5-240327 discloses a structure in which a cap made of a thin metal plate is externally fitted to an end face of a boss portion of a gear, and a sliding surface with an adjacent member is formed on the cap. I have. This configuration makes it easy to assemble, does not mistake the direction of the sliding surface, clarifies the sliding point, stabilizes sliding, easily manages the axial clearance, and prepares multiple types of caps to make the same rotating body various It is said that the present invention can be applied to a rotating device using a pulley and a gear as a rotating body, which can be easily maintained by simply replacing a sliding member.

[0006]

However, in order to prevent the portions of the same or similar material from sliding, and to adjust the axial position of the rotating body, the both end faces of the rotating body and the bearing are provided. In a configuration in which a member such as a spacer, a collar, or a sleeve is inserted between them, there is a problem that assembling work is difficult, and a member that has fallen off from an appropriate position causes malfunction of the rotating body.

In general, since a spacer or a collar does not have a rotation stopper, it is not possible to specify whether to slide with a rotating body or a bearing. Not exclusively.

In particular, the thin plate-shaped spacer is formed by punching a low-friction sheet material as a raw material, and a small protrusion called burrs protrudes from one end surface of the spacer in one side direction, and the burrs do not protrude. The sides should be sliding surfaces. However, it is difficult to determine the front and back of the spacer at the time of the assembling work, and there is a problem that the portion where the burrs are projected is used as the sliding surface, and the spacer cannot be slid smoothly.

Further, in the configuration in which the boss portion of the rotating body is extended, there is a problem that the means for fixing the rotating body to the rotating shaft becomes long. In particular, an idle gear or an idle pulley rotatable with respect to the fixed shaft. In such a case, the bearing inserted between the boss portion of the rotating body and the fixed shaft also needs to be long, which causes a problem that the cost is increased.

In the structure disclosed in Japanese Patent Application Laid-Open No. 5-240327, a metal cap is mounted on the boss of the rotating body, so that the aggressiveness of the adjacent member such as a resin bearing on the sliding surface is reduced. Strongly, there is a problem that the portion where the cap slides is damaged.

An object of the present invention is to provide a rotator device which can facilitate assembling work, can surely prevent wear of the rotator, and can prevent damage to adjacent members. .

[0012]

The present invention has the following arrangement as means for solving the above-mentioned problems.

(1) A plurality of rotating bodies having rotating shafts arranged in parallel with each other are provided. A flange is formed on an end face of the first rotating body, and a flange is formed on an end face of the second rotating body opposed to the flange. It is characterized in that a protruding member is provided which is in contact with the side surface of the flange portion in the axial direction.

In this configuration, the first and second rotators rotate by the contact of the flange of the first rotator with the convex member formed on the end face of the second rotator. Therefore,
The end surface of the second rotator does not directly contact the flange of the first rotator, and the peripheral surface of the second rotator is not damaged. Further, since it is not necessary to bring the convex member into contact with the rotating shaft of the second rotating body, the fastening member for fixing the second rotating body to the rotating shaft does not become longer in the axial direction, and the second Even if the rotating body is an idle rotating body supported on a fixed shaft via a bearing, the bearing does not become long in the axial direction.

(2) The convex member is a member that comes into contact with a side surface of the flange portion within a predetermined range in each of a radial direction and a circumferential direction of the second rotating body.

In this configuration, the convex member formed on the second rotating body comes into surface contact with the flange portion of the first rotating body. Therefore, as compared with the case where the convex member makes point contact or line contact with the flange portion, the contact force per unit area acting on the convex member from the flange portion is reduced, and the convex portion is quickly worn. Absent.

[0017] The convex member according to this configuration may have a trapezoidal cross-sectional shape.

(3) The convex member is a member that comes into contact with a side surface of the flange portion within a predetermined range in a circumferential direction of the second rotating body.

In this configuration, the convex member formed on the second rotating body comes into line contact with the flange portion of the first rotating body. Therefore, the frictional resistance between the flange portion and the convex member is reduced as compared with the case where the convex member comes into surface contact with the flange portion, and the rotation between the first rotary member and the second rotary member is reduced. Torque loss when transmitting force is reduced.

In the convex member according to this configuration, the portion facing the flange portion may have a cross-sectional shape of a corner portion or a partial arc portion.

(4) The convex member is a plurality of members in which a portion facing the flange of the first rotating body is constituted by dots.

In this configuration, the convex member formed on the second rotating body makes point contact with the flange portion of the first rotating body. Therefore, the frictional resistance between the flange portion and the convex member is further reduced as compared with the case where the convex member comes into line contact with the flange portion, and the frictional resistance between the first rotary member and the second rotary member is reduced. Torque loss when transmitting torque is further reduced.

The convex member according to this structure can be formed in a conical shape, a pyramid shape or a partial spherical shape.

(5) The convex member is a member arranged in a single ring or a plurality of rings over the entire circumferential range of the second rotating body.

In this structure, the annular member formed on the second rotating body makes surface contact or line contact with the flange portion of the first rotating body. Therefore, while the first rotating body and the second rotating body are rotating, the convex member constantly contacts the flange portion, and the positional relationship between the first rotating body and the second rotating body is maintained without interruption. Is done.

(6) The convex member is a plurality of members intermittently arranged along the circumferential direction of the second rotating body.

In this configuration, a plurality of convex members arranged along the circumferential direction on the second rotating body contact the flange of the first rotating body intermittently. Therefore, the frictional resistance between the flange portion and the convex member is reduced as compared with the case where the convex member contacting the flange portion is formed in a ring shape, and the first rotating body and the second rotating body are reduced. The torque loss at the time of transmitting the rotational force is reduced.

(7) The projecting member may be configured such that a surface of each of the plurality of members facing the side surface of the flange portion projects from an end face of the second rotating body along a rotating direction of the second rotating body. Is characterized by a gradually reduced slope.

In this configuration, the inclined surfaces of the plurality of convex members formed on the second rotator on the flange portion of the first rotator gradually increase the amount of protrusion from the end surface of the second rotator. Contact. Therefore, when there is a difference in the amount of protrusion from the side surface of the second rotating body between the plurality of convex members,
The impact when the protruding member with a large protrusion comes into contact with the flange is reduced, and the abutment of all the protruding members against the flange is uniform at an early stage due to the wear of the protruding member with a large protrusion. Be transformed into

(8) The convex member may include a plurality of types of members having different amounts of protrusion from the end face of the second rotating body as a set, and the plurality of members may extend along a circumferential direction of the second rotating body. It is characterized by comprising a plurality of sets of members arranged.

In this configuration, first, in each set of the convex members formed on the second rotating body, only the convex member having the largest amount of protrusion comes into contact with the flange portion, and the convex portion having the largest amount of protrusion is formed. After the members are worn by a predetermined amount, the convex member having the largest protrusion amount and the convex member having the second largest protrusion amount in each group abut on the flange portion. Therefore, the area of the convex member abutting on the flange portion gradually increases, the rotation of the first rotating body and the second rotating body is stabilized, and the amount of wear of the convex member decreases.

(9) The convex member is arranged inside a root circle on an end face of a second rotating body which is a gear meshing with an adjacent gear.

In this configuration, a convex member is formed on the end face of the gear, which is the second rotating body, in a range inside the root circle. Therefore, no contact force acts on the teeth of the second rotating body from the flanges, and the teeth are not damaged.

(10) The convex member is formed integrally with an end face of a second rotating body which is a gear having a smaller tooth width than an adjacent gear.

In this configuration, the tooth width is smaller than that of the other gears that mesh with each other, and the convex member is formed integrally with the gear that wears earlier than the other gears. Therefore, the frequency of replacement of the gear having the convex member is higher than that of the other gears, and the convex member is not greatly worn.

(11) The convex member is made of a material softer than the material of the flange portion and is detachably attached to the end face of the second rotating body.

In this configuration, the soft convex member comes into contact with the flange portion of the first rotating body. Therefore,
A first rotating body including the flange portion, wherein the convex member detachably attached to the second rotating body is worn earlier than the flange portion;
In addition, the frequency of replacement of the second rotating body itself is reduced.

[0038]

1A and 1B are a front view and a plan view showing the structure of a rotating body device according to a first embodiment of the present invention. The rotator device 10 includes a driving gear 1,
A relay gear 2 and a driven gear 3 are provided. The drive gear 1 is fixed to the upper end of the drive shaft 4, and the driven gear 3 is fixed to the upper end of the driven shaft 5. The relay gear 2 is an idle gear (idle gear) rotatably supported via a bearing 9 on an intermediate shaft 6 as a fixed shaft, and meshes with the drive gear 1 and the driven gear 3. Drive shaft 4, driven shaft 5, and intermediate shaft 6
Are arranged in parallel with each other. With this configuration, the rotation of the drive shaft 4 in the direction of the arrow L moves from the drive gear 1 to the relay gear 2.
The driven shaft 5 is transmitted to the driven shaft 5 via the driven gear 3, and the driven shaft 5 rotates together with the driven gear 3 in the arrow L direction.

A flange 7 is provided on the upper end surface of the driven gear 3. The outer diameter of the flange 7 is the driven gear 3
And a part of the bottom surface extending outside the driven gear 3 at the flange portion 7 is
Opposes a part of the upper end face of. A convex member 8 is integrally provided on the upper end surface of the relay gear 2. The convex member 8 has an annular flat plate shape whose outer diameter is smaller than the tooth bottom circle of the relay gear 2, and a portion of the upper surface is in surface contact with the bottom surface of the flange portion 7. The axial position of the relay gear 2 is defined by the contact between the flange portion 7 and the convex member 8. That is, when the upper surface of the convex member 8 comes into contact with the bottom surface of the flange portion 7, the upward movement of the relay gear 2 which is fitted on the intermediate shaft 6 and is movable in the vertical direction is restricted.

As described above, in the rotating body device 10 according to this embodiment, since the convex member 8 is formed to protrude from the upper end face of the relay gear 2, the upper end face of the relay gear 2 is No contact with 7. For this reason, the upper end part of the tooth tip of the relay gear 2 does not contact the flange part 7, and this part is not scraped or dropped. Further, since the convex member 8 is integrally provided on the upper end face of the relay gear 2, the number of components can be reduced as compared with a configuration in which separate components such as collars and spacers are arranged, and assembly is possible. Work can be simplified and work reliability can be ensured. Further, since the convex member 8 is provided in a range facing the flange 7 on the upper end surface of the intermediate gear 2, even if the convex member 8 is formed on the relay gear 2, the intermediate shaft 6 passes through the relay gear 2. The axial length of the hole to be formed is not extended, and the bearing 9 does not increase in size.

Further, in the rotating body device 10, since the convex member 8 comes into surface contact with the flange 7, the convex member 8 acts on the convex member 8 as a reaction force of the upward moving force of the relay gear 2. The value of the stress can be reduced. Therefore, the wear rate of the convex member 8 due to the contact with the flange 7 can be suppressed, and even when the flange 7 is made of a harder material than the convex 8, the convex member 8 can be formed.
Is not significantly shortened. Further, in the rotating body device 10, since the convex member 8 is formed in an annular shape over the entire circumference of the relay gear 2, the convex member 8 is rotated while the relay gear 2 is rotating.
Are always in contact with the flange 7, and each gear can be smoothly rotated.

When the projecting member 8 is formed integrally with the relay gear 2, the material of the relay gear 2 is made of a material that is more easily worn than the material of the drive gear 1 and the driven gear 3, thereby providing other It is possible to easily wear the relay gear 2 that is easy to replace as compared with the above-described gear, prevent the gear from being complicated or difficult to replace, and extend the life of the rotating body device 10 itself.

On the other hand, when the convex member 8 is detachably attached to the relay gear 2, the convex member 8 is formed of a material softer than the material forming the flange 7. As a result, only the protruding member 8 is worn, and the gears 1 to
3 can be extended.

FIG. 2 is a front view and a plan view showing a configuration of a rotating body device according to a second embodiment of the present invention. The rotating body device 20 according to this embodiment is configured such that a convex member 18 that is in line contact with the flange portion 7 is formed on the upper end surface of the relay gear 2. That is, the convex member 18 is, for example,
The relay gear 2 has a constant triangular cross-sectional shape over the entire circumference in the circumferential direction, and is in line contact with the flange portion 7 at the top of the triangular cross section.

As described above, in the rotating body device 20 according to the above-described embodiment, since the convex member 18 comes into line contact with the flange portion 7, the contact between the flange member 7 and the convex member 18 is made smaller than when the convex member 18 makes surface contact. The contact area is reduced, and the torque loss due to the frictional resistance generated with the flange portion 7 is reduced, so that the torque can be effectively transmitted from the drive shaft 4 to the driven shaft 5.

The shape of the convex member 18 is not limited to the triangular cross-sectional shape shown in FIG. For example, as shown in FIG. 3, the convex member 18 may have a cross-sectional shape in which the upper end has a partial arc shape.

As shown in FIGS. 4A to 4C,
A plurality of annular convex members 18 may be formed concentrically on the upper end surface of the relay gear 2.

FIGS. 5A and 5B are a front view and a plan view showing a shape of a convex member in a rotating body device according to a third embodiment of the present invention. In the rotating body device 30 according to this embodiment,
A plurality of convex members 28 each having a conical shape are formed intermittently at regular intervals along the circumferential direction on the upper end surface of the relay gear 2. Therefore, the flange 7
Each of the convex members 28 formed on the upper end surface of the relay gear 2 makes point contact with the bottom surface of the relay gear 2. As described above, in the rotating body device 30, since the convex member 28 comes into point contact with the flange portion 7, the contact area with the flange portion 7 is further reduced as compared with the case where the convex member 18 makes linear contact. The torque loss due to the frictional resistance generated between the driving shaft 4 and the portion 7 can be further reduced, and the torque can be more effectively transmitted from the driving shaft 4 to the driven shaft 5.

The convex member 28 is not limited to the conical shape shown in FIG. 5 as long as it has a shape that makes point contact with the bottom surface of the flange 7. For example, as shown in FIG. 6, the convex member 28 may have a hemispherical upper surface.

Further, as shown in FIG. 7, the convex member 28 can be arranged on a plurality of concentric circles on the upper end face of the relay gear 2.

Further, as shown in FIGS. 8A and 8B, the upper surface of the convex member 28 projects from the upper end face of the relay gear 2 along the rotation direction of the relay gear 2 in the direction of the arrow M. May be constituted by an inclined surface in which is gradually reduced. With this configuration, the rotation of the relay gear 2 causes the respective convex members 28 formed on the upper end face of the relay gear 2 to face the bottom surface of the flange portion 7 in order from a portion having a small protrusion amount to a portion having a large protrusion amount. The shape member 28 smoothly contacts the bottom surface of the flange portion 7. Thereby, it is possible to suppress the generation of vibration and noise due to the intermittent contact of each convex member 28 with the flange portion 7.

In the example shown in FIG. 8, each convex member 28
Is designed so that the area of the upper surface gradually decreases along the rotation direction of the relay gear 2. Therefore, the relay gear 2
, The contact area of each convex member 28 with the bottom surface of the flange portion 7 gradually increases, and each convex member 28
Are smoothly in contact with the bottom surface of the flange portion 7.

In addition, as shown in FIGS. 9 (A) to 9 (C), the convex member 28 is made up of two types of convex members 28a and 28b having different protrusion amounts from the upper end face of the relay gear 2. As one set, a configuration in which a plurality of sets are arranged along the circumferential direction of the relay gear 2 may be adopted. According to this configuration, when the protruding member 28a having a large protruding amount is worn due to contact with the bottom surface of the flange portion 7 and the protruding amount of the protruding member 28a matches the protruding amount of the protruding member 28b, The contact area with respect to the bottom surface is increased, and thereafter, the progress of wear is suppressed, and the bottom surface of the flange portion 7 is abutted as an annular convex member 8.

In any of the above embodiments, the relay gear 2 on which the convex members 8, 18, and 28 are formed.
Is described as an idle gear pivotally supported on the fixed shaft 6, but the present invention can be similarly applied to a driven gear fixed to a rotating shaft disposed in place of the fixed shaft 6.
