Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings of FIGS. 1-42:

the spiral force-applying device provided by the invention can be arranged in a case or other fixed structures, and the description is given by taking the case as an example that the spiral force-applying device and a power transmission system are arranged in the case:

specifically, referring to fig. 1-4, the chassis assembly includes the following components: the sealing structure comprises a case 001, a case sealing gasket 002, a case cover 003, a screw four 004, a tapered roller bearing cover 005, a tapered roller bearing cover positioning pin 006, a screw one 007, a hydraulic motor transmission bearing sealing gasket 008, a hydraulic motor transmission bearing cover 009, a case fabrication hole sealing ring 010, a case fabrication hole cover 011, a screw five 012, an oil choke gasket 013, an oil choke 014 and the like.

The parts have the following connection and assembly relations: the case lid 003 passes through fasteners such as five 012 of screw rod and connects in quick-witted case 001 to constitute the holding chamber jointly with quick-witted case 001, and most structure of spiral thrust augmentation device all can be located the holding intracavity.

The middle in the case 001 is provided with a half-hole 025 for installing a tapered roller bearing, the case sealing gasket 002 is arranged on the upper plane of the case 001 for sealing, and the case cover 003 is arranged on the upper plane of the case sealing gasket 002 for sealing various components and parts in the case 001.

The four screws 004 are fixed with the case 001, the tapered roller bearing cover 005 is arranged at the upper end of the middle tapered roller bearing half-hole 025 in the case 001, the positioning pin 006 is positioned by the tapered roller bearing cover, and the first screw 007 is fixed. The hydraulic motor transmission bearing sealing gasket 008 is installed at bearing holes at two sides of the case 001, and the hydraulic motor transmission bearing cover 009 is installed on two planes of the hydraulic motor transmission bearing sealing gasket 008 and fixed with the case 001 by a screw 007. The case process hole sealing rings 010 are installed at the process hole positions at the two ends of the case 001, and the case process hole covers 011 are installed on the two planes of the case process hole sealing rings 010 and are fixed with the case 001 through the screws five 012. An oil port choke plug gasket 013 is installed at the bottom of the case 001 and at the upper part of the case cover 003, and an oil port choke plug 014 is installed at the plane of the oil port choke plug gasket 013. Thus, the integral installation of the chassis component can be realized.

The spiral force application device in the present application can also be regarded as a nut rolling power machine, which specifically includes a spiral force application component and a lever component, the spiral force application component includes a spiral shaft 040, a rolling element unit and a rolling element connecting seat, the spiral shaft 040 has spiral blades, the rolling element connecting seat mainly includes a seat body 044, the seat body 044 has a central revolving hole 0441 and a plurality of revolving cavities 0442 communicated with the central revolving hole 0441, the plurality of revolving cavities 0442 are disposed on the peripheral side of the central revolving hole 0441, the spiral shaft 040 is disposed in the central revolving hole 0441, the rolling element unit includes a power transmission piece 041 and a plurality of rolling elements capable of rolling relative to the power transmission piece 041, the power transmission piece 041 is correspondingly disposed in the revolving cavity 0442, and a first end of the power transmission piece 041 extends into a gap between the spiral blades, the plurality of rolling elements are disposed at least on the circumferential outer side of a second end of the power transmission piece 041, and the rolling bodies are in rolling contact with the wall of the turning cavity 0442.

The lever assembly comprises a rotating seat, a supporting arm 057 and a connecting arm 049, the first end of the supporting arm 057 is rotatably connected with the rotating seat (formed by components such as a supporting rod rolling body cushion cover 060 and the like in the figure), and the second end of the supporting arm 057 extends to the rolling body connecting seat and is rotatably connected between the two ends of the connecting arm 049; the first end of the connecting arm 049 is rotatably connected with the side of the rolling element connecting seat, so that the rolling element connecting seat is driven by the rotation of the spiral shaft 040 to translate along the axial direction of the spiral shaft 040.

The second end of the connecting arm 049 is configured to move under the urging of the first end of the connecting arm 049 to output a torque.

In the above-described configuration, the screw shaft 040 in the screw biasing means is connectable to an external structure for inputting power and torque, and the power transmission element 041 in the rolling element connecting base abuts against the side surface of the spiral blade of the screw shaft 040 with the rotation of the screw shaft 040, and is pushed by the spiral blade to move. The seat body 044 of the rolling body connecting seat is connected through structures such as the supporting arm 057, the space position of the seat body 044 is limited, and therefore the seat body 044 cannot rotate and only can translate. Thus, the power transmission member 041 can move the seat body 044 only in the axial direction of the spiral shaft 040 by the spiral blade. Thus, the rotation of the spiral shaft 040 can be converted into the translational motion of the rolling element connecting seat.

The spiral blade of the spiral shaft 040 is an archimedes spiral, and when the spiral shaft 040 rotates, the spiral blade drives the power transmission member 041 to move in a labor-saving manner, so that when the spiral shaft 040 rotates, the spiral shaft 040 can provide a small torque, and generates a large linear thrust through the archimedes spiral transmission, thereby achieving a labor-saving effect.

In the rolling element connecting seat, each rolling element unit specifically provided includes a plurality of rolling elements capable of rolling relative to the power transmission element 041, in addition to the power transmission element 041. The rolling elements are arranged around the circumference of the power transmission element 041. Because the abutting part of the spiral blade and the power transmission member 041 changes constantly when the spiral shaft 040 rotates, the direction and magnitude of the generated torque also change accordingly, if the power transmission member 041 directly contacts the seat body 044 and power is transmitted by means of sliding friction between the two, the direction and magnitude of the friction force between the power transmission member 041 and the seat body 044 are inconsistent with the moving direction of the seat body 044 or a motion dead point is generated between the power transmission member 041 and the seat body 044 due to the reason that the direction and magnitude of the friction force change at any time, so as to hinder the movement of the seat body 044, and in addition, the higher friction force also causes accelerated wear between the power transmission member 041 and the seat body 044, thereby further affecting the transmission efficiency. Therefore, when the power transmission element 041 moves under the acting force of the helical blade, the rolling element can obviously reduce the friction force between the power transmission element 041 and the seat body 044 by virtue of the rolling connection between the rolling element and the power transmission element 041 and the wall of the rotary cavity 0442, so that the power loss of the power transmission element 041 during torque transmission is reduced, and the power transmission efficiency of the boosting assembly is improved.

In order to maintain the continuous power output of the screw biasing means, the rotation direction of the screw shaft 040 may be periodically changed, that is, the reciprocating forward rotation and reverse rotation, and accordingly, the rolling element link base is also reciprocated along the axis of the screw shaft 040.

When the rolling element connecting base outputs reciprocating linear movement, correspondingly, the lever assembly changes the transmission direction of the variable force through the lever action and amplifies the torque output by the rolling element connecting base, so that the second end of the connecting arm 049 in the lever assembly can output larger power torque.

In an alternative form, the distance between the first end of the connecting arm 049 and the lateral connecting point of the rolling element connecting seat (the main part is the seat body 044) is greater than the distance between the second end of the connecting arm 049 and the lateral connecting point of the rolling element connecting seat. That is to say, the side connecting point of the connecting seat of the rolling element is used as a fulcrum, and the length of the force arm at the first end (power input end) of the connecting arm 049 is greater than that at the second end (power output end) of the connecting arm 049, so as to output a larger moment.

The following describes a specific construction of the screw force application assembly and the lever assembly with reference to an example: in one embodiment, the screw force assembly may include the following parts: the connecting seat comprises a spiral shaft 040, a power transmission piece 041, a first rolling body 042, a top bead 043, a seat body 044, a reciprocating stressing frame end cover 045, a second screw 046, a third screw 047, a reciprocating stressing frame 048, a connecting arm 049, a first lever rolling piece 050, a second lever rolling piece 051, a third lever rolling piece 052, a lever rolling piece retainer ring 053, a lever shaft 054, a lever shaft retainer ring 055, a rolling piece spacer 056, a supporting arm 057, a first supporting rod rolling piece 058, a second supporting rod rolling piece 059, a supporting rod rolling piece cushion cover 060 and the like, wherein the supporting rod rolling piece cushion cover 060 and the like jointly form the connecting seat.

The spiral shaft 040 is mounted on the tapered roller bearing 025, the power transmission piece 041 is mounted in a base body 044, the first rolling body 042 is mounted on the power transmission piece 041, the top ball 043 is mounted at the cone at the upper end of the power transmission piece 041, the base body 044 is mounted at the outer circle of the spiral shaft 040, the reciprocating stressing frame 048 is mounted at the outer circle of the base body 044, and the reciprocating stressing frame end cover 045 is mounted at least one end of the base body 044 and fixed by a screw three 047 and a screw two 046, so that a connecting sleeve is formed together with the reciprocating stressing frame 048.

Lower holes of a connecting arm 049 are arranged at trunnions at two ends of a reciprocating stressing frame 048, a first lever rolling piece 050 is arranged at the lower holes of the connecting arm 049, a second lever rolling piece 051 is arranged at the middle hole of the connecting arm 049, a third lever rolling piece 052 is arranged at the upper hole of the connecting arm 049, lever rolling piece retainer rings 053 are arranged on half shafts at two ends of the reciprocating stressing frame 048, and a lever shaft 054 is arranged at the middle hole of the connecting arm 049 and is connected with a supporting arm 057. The lever shaft stop 055 is mounted on the lever shaft 054, the rolling element spacer 056 is mounted outside the upper hole of the connecting arm 049, and the other rolling element spacer 056 is mounted inside the upper hole of the connecting arm 049. The supporting arm 057 is arranged on the lever shaft 054 and is connected with the connecting arm 049, the first supporting rod rolling piece 058 is arranged at the rear hole of the supporting arm 057, the second supporting rod rolling piece 059 is arranged at the front hole of the supporting arm 057, and the supporting rod rolling body cushion cover 060 is arranged outside the rear hole of the supporting arm 057.

When the spiral shaft 040 rotates, the power transmission member 041 is driven to roll in a spiral groove formed by spiral blades of the spiral shaft 040 and a rotary cavity 0442 of the seat body 044, the reciprocating stressing frame 048 is driven to move back and forth, and when the reciprocating stressing frame 048 moves back and forth, the connecting arm 049 and the supporting arm 057 are driven to cooperate to swing back and forth to apply force to the connecting arm 049, so that power is output by the lever swinging back and forth to apply force.

As described above, according to the archimedes screw principle, a relatively large linear thrust can be generated by the archimedes screw transmission with a relatively small torque, so that the screw force application device, or the nut rolling power machine, replaces the screw and nut transmission with the nut rolling and screw transmission, the rolling transmission effectively improves the transmission efficiency, and the defects of low sliding transmission efficiency, easy abrasion and difficult high speed of the existing cylindrical screw are overcome.

The specific composition of the rolling element connecting seat and the rolling element unit is described in more detail as follows:

optionally, in the rolling element unit, the plurality of rolling elements includes a plurality of first rolling elements 042, the first rolling elements 042 are disposed circumferentially outside the second end of the power transmission member 041, and the circumferential side wall of the power transmission member 041 and the cavity wall of the rotation cavity 0442 are in rolling contact with the first rolling elements 042. In this way, a low-friction power transmission and connection is achieved between the power transmission element and the rotary cavity 0442 of the housing via the first rolling elements 042.
