It is widely used in industrial and agricultural applications such as oil drilling, power transmission, ship lifting and unloading, elevator lifting, etc.

[0003] The inner take-up double twisting machine is the main equipment in the twisting process. The flywheel pulley is an important transmission component on the flywheel disc of the main machine. Due to the coarse specifications of the cord, the tension of the take-up and pay-off is large, the running speed is fast, and the technician needs to adjust the angle of the flywheel pulley to adjust the back wire, so that the force point of the pin shaft changes from surface contact to point contact. The flywheel pulley bears a lot of tension, resulting in a short service life of the flywheel pulley;

[0004] The frequency of existing flywheel pulley failure reports is very high, mainly due to the failure of the SF bushing in the flywheel pulley, which poses a great hidden danger to the cord production quality.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0033] like Figures 1 to 9 As shown, the utility model is a self-lubricating flywheel pulley assembly of a strand twisting machine, comprising: a bracket 1, a pin shaft 2 rotatably mounted on the side wall of the bracket 1, a pulley body 4 sleeved on the outer edge of the pin shaft 2, and a lubrication mechanism for automatically lubricating the pin shaft 2 and the pulley body 4; a bushing 5 is installed between the pulley body 4 and the pin shaft 2, and a gasket 6 is installed between the flywheel body 4 and the bracket 1.

[0034] The lubrication mechanism includes: a box body 7 for storing lubricant, the box body 7 is fixedly installed on one side of the bracket 1, a cavity 3 is opened inside the pin shaft 2, a conveying component for conveying the lubricant in the inner cavity of the box body 7 to the cavity 3, and a control component for controlling the lubricant to flow from the cavity 3 to the pulley body 4; the conveying component includes: a connecting pipe 8 plugged and installed at one end of the pin shaft 2, a discharge pipe 9 for conveying the lubricant from the inner cavity of the box body 7 to the inner cavity of the connecting pipe 8, one end of the discharge pipe 9 is plugged and installed at the bottom of the box body 7, and the other end is rotatably installed at one end of the connecting pipe 8, a ring 10 fixedly sleeved on the outer edge of the connecting pipe 8, a mounting groove opened on the outer edge of the ring 10, a linkage bar 11 movably installed in the inner cavity of the mounting groove, and a linkage plate fixedly installed on one side of the linkage bar 11 22, a linkage spring 23 fixedly mounted between the linkage plate 22 and the inner wall of the mounting groove, and a linkage unit for controlling the switch of the inner cavity of the discharge pipe 9; the linkage unit includes: a rotating rod rotatably mounted on the side wall of the discharge pipe 9, a fixed plate 21 fixedly mounted at one end of the rotating rod, a driven bevel gear 16 fixedly mounted at the other end, a rotating shaft 12 rotatably mounted at the bottom of the housing 7, an active bevel gear 14 fixedly sleeved on the outer edge of the rotating shaft 12 and meshing with the driven bevel gear 16, and a torsion spring 15 for driving the active bevel gear 14 to reset, one end of the torsion spring 15 fixedly mounted on the top of the active bevel gear 14, and the other end fixedly mounted on the bottom of the housing 7, and sleeved on the outer edge of the rotating shaft 12 and fixedly mounted on the outer side of the rotating shaft 12. Connecting plate 13.

[0035] When the pulley body 4 rotates, the pin shaft 2 can be driven to rotate, and the connection tube 8 can be driven to rotate through the rotation of the pin shaft 2, and the ring 10 can be driven to rotate through the connection tube 8. When the ring 10 rotates, since the linkage bar 11 is movably installed in the inner cavity of the installation groove at the outer edge of the ring 10, the linkage bar 11 can generate centrifugal force. Through the action of the centrifugal force, the linkage bar 11 moves outward from the inner cavity of the installation groove, that is, the linkage bar 11 drives the linkage plate 22 to move, and the linkage plate 22 drives the linkage spring 23 to stretch. When the linkage bar 11 moves outward from the inner cavity of the installation groove, it can abut against the connection plate 13. When the linkage bar 11 rotates to abut against the connection plate 13, the connection plate 13 is toggled, so that the connection plate 13 rotates;

[0036] The connecting plate 13 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the active bevel gear 14 to rotate, and the active bevel gear 14 drives the driven bevel gear 16 to rotate, and drives the torsion spring 15 to twist, and the driven bevel gear 16 drives the rotating rod to rotate, and the rotating rod drives the fixed plate 21 to rotate. When the fixed plate 21 rotates, the fixed plate 21 does not have a sealing effect on the inner cavity of the discharge pipe 9. At this time, the lubricant in the inner cavity of the box body 7 flows into the inner cavity of the discharge pipe 9 by gravity, and flows into the inner cavity of the connecting pipe 8 through the discharge pipe 9, and enters the cavity 3 through the connecting pipe 8, so as to facilitate the subsequent lubrication work;

[0037] When the linkage bar 11 rotates and no longer contacts the connecting plate 13, the active bevel gear 14 can be driven to reset by the elastic force of the torsion spring 15, the rotating shaft 12 can be driven to reset by the active bevel gear 14, the connecting plate 13 can be driven to reset by the rotating shaft 12, and the fixed plate 21 can be driven to reset, so that the fixed plate 21 can seal the inner cavity of the discharge pipe 9 again, so that the lubricant no longer flows from the discharge pipe 9 into the connecting pipe 8;

[0038] Through the above-mentioned mechanism of the present application, when the pulley body 4 rotates, the lubricant in the inner cavity of the box body 7 can be automatically transported to the cavity 3 on the pin shaft 2. When the pulley body 4 stops rotating, the lubricant in the inner cavity of the box body 7 is automatically stopped from being transported to the cavity 3 on the pin shaft 2. Thus, when the pulley body 4 is running, the lubricant can be automatically transported without manual operation, thereby improving practicality.

[0039] A slider 24 is fixedly installed on one side of the linkage plate 22, and a slide groove is provided on the inner wall of the installation groove. The slider 24 is located in the inner cavity of the slide groove. When the linkage plate 22 moves, the slider 24 can be driven to slide in the inner cavity of the slide groove. Through the mutual cooperation between the slider 24 and the slide groove, the linkage plate 22 can be limited, so that the linkage plate 22 has higher stability during movement.

[0040] The control component includes: a through hole opened on the side wall of the pin shaft 2, a fixed plate 21 fixedly installed on the inner wall of the through hole, an opening opened on the fixed plate 21, an arc plug 19 for sealing the opening on the fixed plate 21, and a reset unit for driving the arc plug 19 to reset; the reset unit includes: a fixed bar 18 fixedly installed on the inner wall of the through hole, a movable rod 17 installed on the side wall of the fixed bar 18, one end of the movable rod 17 is fixedly installed on the top of the arc plug 19, and the other end is fixedly installed with a fixed block, and a reset spring 20 fixedly installed between the arc plug 19 and the fixed bar 18.

[0041] When the pulley body 4 rotates, the pin shaft 2 can be driven to rotate. When the pin shaft 2 rotates, the arc plug 19 can generate centrifugal force, thereby separating the arc plug 19 from the fixed plate 21 and driving the return spring 20 to compress. At this time, the lubricant in the cavity 3 enters the bushing 5 through the through hole, so that the bushing 5 is fully lubricated and wear and damage are reduced.

[0042] When the pulley body 4 stops rotating, the arc plug 19 can be reset by the elastic force of the reset spring 20. At this time, the lubricant in the cavity 3 cannot enter the bushing 5 through the through hole. Therefore, when the pulley body 4 and the bushing 5 are maintained, the lubricant will not flow out of the cavity 3, resulting in waste of lubricant.

[0043] It is supplemented here that a plurality of through holes are opened on the outer edge of the pin shaft 2 , and the through holes are arranged in a circular array on the outer edge of the pin shaft 2 , so that the lubricant can be evenly transported to the inner cavity of the bushing 5 .

[0044] Through the lubrication mechanism of the present application, the lubricant in the box 7 can be automatically transported to the cavity 3 when the pulley body 4 is running, thereby realizing self-lubrication between the pulley body 4 and the cavity 3, fully ensuring the lubrication effect between the pulley body 4 and the pin shaft 2, reducing wear and damage, and effectively extending the life of the pulley body 4, thereby reducing production costs, improving production efficiency, stabilizing product quality, and reducing the labor intensity of maintenance personnel.

[0045] Working principle: When in use, the rotation of the pulley body 4 can drive the lubrication mechanism to operate, so that the lubricant in the inner cavity of the box body 7 can be automatically transported to the cavity 3, thereby realizing self-lubrication between the pulley body 4 and the cavity 3, fully ensuring the lubrication effect between the pulley body 4 and the pin shaft 2, reducing wear and damage, and effectively extending the life of the pulley body 4.

[0046] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
