Problems solved by technology

However, there may be lubricating oil leakage at the power input and output ports. In the prior art, the sealing effect is generally achieved by installing seals. Traditionally used seals will have certain gaps. When rotating at high speed, due to the large internal pressure, making Lubricating oil is easy to leak out from the gap, resulting in a decrease in the amount of internal lubricating oil, increased friction between parts, and reduced service life of the product. In addition, when rotating at high speed, it is easy to generate friction and heat, resulting in rapid wear of the seal. resulting in oil leakage

Embodiment 1

[0028] An anti-leakage worm gear, comprising a box body 1, a worm screw 3 and a worm wheel 10, the inside of the box body 1 is provided with two through grooves, which are respectively the turbine through grooves in the front and rear directions and the worm through grooves in the left and right directions. The groove communicates with the middle part of the worm channel, and is used for transmission between the worm 3 and the worm wheel 10. The worm 3 is installed in the worm channel. It runs through the right side of the box body 1 and is rotationally connected with the box body 1 through the first bearing 1. The worm 3 is connected with the external power equipment when in use as the input end of the reducer. The worm wheel 10 is located in the turbine channel. 10 meshes with the worm 3. When the worm 3 rotates, it can drive the worm wheel 10 to rotate. The middle part of the worm wheel 10 is connected to the output shaft 6. The rear end of the output shaft 6 is connected to...

Embodiment 2

[0034] The difference between this embodiment and embodiment one is:

[0035] In this embodiment, the left side of the box body 1 is provided with a through hole, and the position of the through hole corresponds to the position of the worm 3, and a sealing cover 8 is installed in the through hole, and the sealing cover 8 is connected with the left end of the worm screw 3 through bearing rotation, and the The sealing cover 8 can facilitate the installation and disassembly of the worm 3, and also includes an input mounting seat 9 and an input flange 2. The input mounting seat 9 is installed on the right side of the box body 1, and the middle part of the input mounting seat 9 is hollow. And the diameter of the inner wall is greater than the diameter of the worm 3, so that the worm 3 does not contact the input mounting seat 9, the input flange 2 and the input mounting seat 9 are connected by six screws, and the first bearing 4 is installed in the middle of the input flange 2, The ...

Embodiment 3

[0037] The difference between this embodiment and embodiment one is:

[0038]This embodiment also includes solid lubricating grease 12. The solid lubricating grease 12 is located between the second bearing 13 and the O-ring 7, which can reduce the frictional heat generated during high-speed rotation and improve the sealing quality. The principle of incompatibility of the grease 12 prevents the internal lubricating oil from passing through the solid grease 12 to achieve the purpose of sealing. The O-shaped sealing ring 7 is provided with a filling hole 11 for injecting the solid grease 12. The solid grease The installation method of 12 includes the following steps:

[0039] 1) Firstly, an injection hole 11 is opened on the O-ring 7 as an injection port for the solid lubricating grease 12;

[0040] 2) liquefying the solid grease 12 at high temperature, and extracting a vacuum to discharge the air inside the solid grease 12;

[0041] 3) Then inject the liquefied solid grease 12...

Abstract

The invention discloses an assembly process of a leak-proof worm-gear-and-worm. The leak-proof worm-gear-and-worm comprises a box body, a worm and a worm gear. Two through slots are formed in the boxbody, the two through slots are separately a worm gear through slot in the front-and-back direction and a worm through slot in the left-and-right direction, the worm gear through slot communicates with the middle part of the worm through slot, the worm is arranged in the worm through slot, the left end of the worm is rotatably connected with the left side surface of the box body through bearings,the right end of the worm penetrates through the right side surface of the box body and is rotatably connected with the box body through the first bearing, the worm gear is located in the worm gear through slot, the worm gear meshes with the worm, the middle part of the worm gear is connected with an output shaft, the rear end of the output shaft is rotatably connected with the rear side surface of the box body, and the front end of the output shaft penetrates through the front side surface of the box body. According to the assembly process of the leak-proof worm-gear-and-worm, lubricating oilleakage can be prevented, the abrasion degree of a sealing element is reduced, the sealing quality is improved, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the technical field of reducer assembly and sealing, in particular to an anti-leakage worm gear assembly process. Background technique [0002] The reducer is the intermediate link in which the power unit drives the actuator, and it converts high-speed low-torque into low-speed high-torque through the cooperation of the worm and worm gear. Generally, in order to ensure the efficient operation of the reducer, lubricating oil is filled inside to reduce friction and improve operating efficiency. However, there may be lubricating oil leakage at the power input and output ports. In the prior art, the sealing effect is generally achieved by installing seals. Traditionally used seals will have certain gaps. When rotating at high speed, due to the large internal pressure, making Lubricating oil is easy to leak out from the gap, resulting in a decrease in the amount of internal lubricating oil, increased friction between parts, and red...
