Abstract
Description
Technical Field
[0001] The utility model belongs to the field of transmission structures and relates to a gear, in particular to a self-lubricating gear. Background Art
[0002] Gears are mechanical parts with teeth that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field.
[0003] Traditional mechanical gears that mesh with each other need to be lubricated on the inner and outer rings of the gears from time to time. However, since the machine needs to be shut down for gear maintenance and is in production needs, the gears are rarely lubricated in a timely manner when they need to be lubricated. This will cause excessive friction between the gears, causing accelerated gear wear and reduced lifespan. Excessive friction will cause the machine to make noise. At the same time, due to dry grinding between the gears, the machine needs to consume more energy to complete normal operation.
[0004] For example, the anti-backlash gear with application number 202220914926.1 includes a first gear and a second gear, which are locked by a connecting piece and a limit piece. An anti-backlash piece is arranged between the first gear and the second gear, and a piston rod and a ball are arranged on the anti-backlash piece. The ball is driven by centrifugal force, and then the piston rod is driven. The piston rod causes the first gear and the second gear to be misaligned to provide a buffer.
[0005] The above patent drives the first gear and the second gear to be misaligned by means of balls and pistons, eliminates the spring buffer design, and increases the service life of the anti-backlash gear. However, the lubricating oil between the gears still needs to be frequently applied, which is cumbersome to use. Utility Model Content

DETAILED DESCRIPTION
[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0022] like Figures 1 to 5 As shown, the utility model can be implemented through the following embodiments: a self-lubricating gear includes a gear body 1, the gear body 1 is provided with gear teeth 11, the gear body 1 is provided with an oil storage tank 12, the oil storage tank 12 is installed with a locking cover 2, the oil storage tank 12 is provided with a small flow channel 121, the outlet of the small flow channel 121 is provided between the gear teeth 11, the inlet of the small flow channel 121 is provided with a mounting hole 122, an overflow structure 3 is installed in the mounting hole 122, and the gear and the locking cover 2 are fixedly connected by a countersunk screw 4.
[0023] The oil storage tank is used to store lubricating oil, and the locking cover 2 is used to seal the oil storage tank to prevent the lubricating oil from leaking from the slot. The small flow channel 121 and the overflow structure 3 cooperate to ensure that the lubricating oil flows out of the gear when working.
[0024] like Figure 4 As shown, the overflow structure 3 is in the shape of a stepped column, and the overflow structure 3 is divided into a stepped column 1 31 and a stepped column 2 32, and a clamping ring 311 is arranged outside the stepped column 1 31. The stepped column shape is convenient for processing, and the step formed by the stepped column 2 32 and the stepped column 1 31 positions the overflow structure 3 in the mounting hole 122, and the clamping ring 311 is used to limit the overflow structure 3.
[0025] like Figure 4 As shown, a mounting groove 33 is provided in the step column 1 31 and the step column 2 32, and an oil sealing plug 34 is installed in the mounting groove 33. A spring 5 is installed between the oil sealing plug 34 and the mounting groove 33, and the spring 5 is in a compressed state. In addition to installing the oil sealing plug 34, the mounting groove 33 also provides an oil outlet channel; the oil sealing plug 34 is used to block the overflow structure 3 when the gear stops working; the spring 5 is in a compressed state to provide the pressure required for overflow, so as to prevent the hydraulic pressure of the lubricating oil from pushing open the oil sealing plug 34 when the gear stops working.
[0026] like Figure 4 As shown, an oil sealing port 331 is provided in the installation groove 33, and a long rod 341 is provided on the oil sealing plug 34, and the long rod 341 blocks the oil sealing port 331. The oil sealing port 331 and the long rod 341 cooperate to block the installation groove 33 to prevent the residual lubricating oil in the installation groove 33 from flowing out from the small flow channel 121, resulting in waste.
[0027] like Figure 2 , Figure 3 and Figure 5As shown, the locking cover 2 is covered with a sealing rubber ring 6, the rubber ring is provided with a sealing protrusion 61, and the oil storage tank is provided with a matching sealing groove 123. The sealing protrusion 61 on the sealing rubber ring 6 cooperates with the sealing groove 123 to improve the sealing performance of the oil storage tank.
[0028] like Figure 2 and Figure 3 As shown, a groove 124 is provided at the notch of the oil storage tank, a gasket 7 is installed in the groove 124, and a corresponding extension edge 21 is provided on the locking cover 2. The groove 124 and the extension edge 21 are provided to form a corner to prevent the lubricating oil from flowing out directly from the gap between the locking cover 2 and the oil storage tank. The gasket 7 provides a sealing effect and provides a buffer for the contact between the extension edge 21 and the groove 124.
[0029] like Figure 1 and Figure 2 As shown, a countersunk screw hole 211 is provided at the extension edge 21, and a countersunk screw 4 passes through the countersunk screw hole 211 and the groove 124. The countersunk screw hole 211 is used to fasten the locking cover 2 and the oil storage tank by passing through the countersunk screw hole 211 and the groove 124, so as to facilitate the removal of the oil storage tank and replenishing the lubricating oil.
[0030] The working principle of the utility model is as follows: after the lubricating oil is added to the oil storage tank, the locking cover 2 is covered and the countersunk screw 4 is screwed on. When the gear is working, the centrifugal force generated by the high-speed rotation of the gear further strengthens the pressure applied to the overflow structure 3, and overcomes the pressure of the spring 5, causing the spring 5 to be compressed, and the oil sealing plug 34 is pushed into the installation groove 33, so that the long rod 341 moves and opens the oil sealing port 331, and the lubricating oil flows into the installation groove 33, and flows into the small flow channel 121 from the oil sealing port 331, and finally flows to between the gear teeth 11, completing the lubrication of the gear teeth 11; when adding the lubricating oil, unscrew the countersunk screw 4, remove the locking cover 2, and pour the lubricating oil into the oil storage tank.
[0031] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0032] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
