Description
Technical Field
The utility model relates to a speed reducer field, concretely relates to self-lubricating awl smooth gear case.
Background
The speed reducer is widely applied to the field of machinery, and converts high-speed motor input into low-speed high-torque output. The input shaft of speed reducer is the high-speed shaft, and the bearing that the input shaft corresponds rotates at a high speed and produces a large amount of heats in the work engineering, if can not in time lubricate, the bearing is because of high temperature inefficacy easily, reduces the life-span of speed reducer. In the prior art, a speed reducer bearing is lubricated in a manner of an oil thrower and an oil groove, but for a bevel gear transmission speed reducer, the base oil lubrication is insufficient in the bevel gear meshing process, a high-speed shaft bearing cannot be lubricated, the high-speed shaft bearing is easy to lose efficacy due to high temperature, and the service life of the speed reducer is shortened.
Disclosure of Invention
For solving the insufficient problem of bevel gear speed reducer high-speed shaft bearing lubrication among the prior art, the utility model aims to provide a self-lubricating smooth gear box of awl.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
the utility model provides a self-lubricating awl smooth gear case, includes the box, and the box comprises last box and lower box, has input shaft, multistage jackshaft and output shaft by the bearing support between upper and lower box, and the input shaft has the vice drive output shaft of driving gear by the vice multistage jackshaft of bevel gear drive, multistage jackshaft, and the input shaft is installed in one side of box and is perpendicular with multistage jackshaft and output shaft, its characterized in that, the top of going up the box is the inclined plane, and the inclined plane inclines to the input shaft top from the output shaft top, install the oil trap on the tank wall of input shaft top, be equipped with the oil leak hole on the oil trap, the oil leak hole is located directly over the input shaft.
Furthermore, the input shaft is supported on one side of the box body through a bearing seat, and the oil leakage hole is located right above the bearing seat.
Furthermore, an oil inlet is processed on the bearing seat, and the oil inlet is communicated with a bearing in the bearing seat and the outside of the bearing seat.
And furthermore, an end cover is arranged at the extending end of the output shaft, a sealing ring is arranged between the end cover and the output shaft, and the end cover is fixedly connected with the outer wall of the box body.
After taking above technical scheme, the beneficial effects of the utility model are that: the upper body and the lower body of the gear box are arranged to be inclined planes, the oil thrower or the gear wheel is thrown out through the inclined planes and guided to the vertical box wall supporting the high-speed shaft, an oil collecting tank is arranged on the wall of the gear box to collect lubricating oil, an oil leakage hole is formed in the position of the oil collecting tank corresponding to a bearing seat of the high-speed shaft, and the lubricating oil is accurately dripped into a bearing chamber to be lubricated. The technical scheme can fully lubricate the bearing of the high-speed shaft and prolong the service life of the speed reducer.

Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:
as shown in the figure, the self-lubricating bevel pulley box comprises a box body 1, an input shaft 2, a multi-stage intermediate shaft and an output shaft, wherein the box body 1 consists of an upper box body and a lower box body, and the input shaft 2, the multi-stage intermediate shaft and the output shaft are supported between the upper box body and the lower box body through bearings. The input shaft 2 is driven by a bevel gear pair to drive a multi-stage intermediate shaft, the multi-stage intermediate shaft is provided with a transmission gear pair to drive an output shaft, the input shaft 2 is arranged on the side wall of one side of the box body 1 by a bearing seat 3, and the input shaft 2 is vertical to the multi-stage intermediate shaft and the output shaft. The top surface of the box body inclines to the left side wall and the right side wall of the box body 1 from the right upper side of the output shaft to two sides. An oil collecting tank 5 is fixedly arranged at the joint of the side wall 4 supporting the input shaft 2 and the top surface of the box body, an oil leakage hole 6 is processed on the bottom surface of the oil collecting tank 5, and the oil leakage hole 6 is positioned right above the input shaft bearing seat 3. An oil inlet hole 7 is processed on the bearing seat 3 of the input shaft 2, lubricating oil dropping from the oil leakage hole 6 of the oil collecting groove 5 enters the bearing seat 3 from the oil inlet hole 7, and a bearing in the multi-shaft bearing seat 3 is lubricated.
In order to prevent the leakage of lubricating oil, an end cover 8 is mounted on the outer end face of the bearing seat 3, the end cover 8 is sleeved on the input shaft 2, a sealing ring is mounted between the end cover 8 and the input shaft 2, and the end cover 8 is fixed with the box body 1 through screws.
