Compact speed reducer with independent lubrication sealing cavity

Abstract

The invention relates to compact speed reducer with an independent lubrication sealing cavity. The compact speed reducer comprises a box body, a gear set, an output shaft, a support, an output shaft linkage hole, a bearing assembly and a sealing mechanism, and is characterized in that a sealing spacer bush arranged on the periphery of the output shaft in a sleeved mode is arranged at the position,located in the middle of the output shaft linkage hole, of the box body; a first lubrication sealing cavity is arranged between the sealing spacer bush and the output shaft; a second lubrication sealing cavity is arranged between the sealing spacer bush and the box body; an O-shaped ring located between the box body and the sealing spacer bush is embedded in one end of the sealing spacer bush; and a first oil seal located between the output shaft and the sealing spacer bush is arranged at the other end of the sealing spacer bush. The compact speed reducer with the independent lubrication sealing cavity provided by the invention has the beneficial effects that the lubrication effect is good, the vertical installation stirring function can be achieved, the sealing performance is reliable, the transmission efficiency is high, and the bearing capacity is high.

Description

technical field [0001] The invention relates to the technical field of reducer equipment, in particular to a compact reducer with an independent lubricating and sealing chamber. Background technique [0002] The reducer is an independent component composed of gear transmission, worm transmission, gear and worm transmission enclosed in a rigid shell, and is often used as a reduction transmission device between the original moving part and the working machine. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator, and is widely used in modern machinery. [0003] Now take the reducer acting in the mixing equipment as an example. The motor of the reducer and the reducer mechanism are arranged in parallel, installed vertically, and the output is set downward, which can meet the mixing requirements of the reducer. However, the requirements for the reducer of the mixing equipment are "It has the characteristics of small spe...

Problems solved by technology

[0003] Now take the reducer acting in the mixing equipment as an example. The motor of the reducer and the reducer mechanism are arranged in parallel, installed vertically, and the output is set downward, which can meet the mixing requirements of the reducer. However, the requirements for the reducer of the mixing equipment are "It has the characteristics of small speed ratio, fast speed, compact structure, temperature rise of the reducer, and sensitivity to oil leakage." However, the existing reducer often has the following two problems. One is that the temperature rise is too high, which will lead to The internal parts are aging, which shortens the service life. The second is oil leakage. Once the above phenomenon occurs, it will be inconvenient to maintain because the shaft of the reducer is not easy to replace, and the maintenance cost is high, which will bring great inconvenience to users.
