Speed reducer shell and speed reducer

Abstract

The embodiment of the invention provides a speed reducer shell and a speed reducer. The shell comprises a shaft hole used for installing an oil seal and a bearing seat positioned on the inner wall ofthe shell and used for installing a bearing, a transition hole is formed between the shaft hole and the bearing seat, the inner wall of the shell comprises an oil storage pool and an oil guide channel, lubricating oil splashed to the inner wall of the shell is received through the oil storage pool, and the oil storage pool is positioned on the outer side of the outer periphery of the bearing seat;openings at the two ends of the oil guide channel are respectively positioned in the oil storage pool and the transition hole and communicate the oil storage pool with the transition hole, and the vertical height of the opening, at the end of the oil storage pool, of the oil guide channel is higher than the vertical height of the bottom of the transition hole. According to the speed reducer shelland the speed reducer, the lubricating oil is collected by arranging the oil storage pool on the inner wall of the speed reducer shell, and the lubricating oil collected by the oil storage pool is guided to the transition hole through the oil guide channel, so that the lubricating and heat dissipation requirements of the oil seal at high rotating speed are met.

Description

technical field [0001] The embodiments of the present invention relate to the field of reducers, and more specifically, to a reducer housing and a reducer. Background technique [0002] The reducer is an independent component composed of a gear transmission enclosed in a rigid shell, and is often used as a reduction transmission device between the prime mover and the working machine; it matches the speed and transmission between the prime mover and the working machine or the actuator The role of torque is widely used in modern machinery. [0003] The motor transmits speed and torque to the reducer through the input shaft, and the input shaft of the reducer is supported by the bearing in the bearing seat of the reducer housing. In order to achieve efficient torque transmission, it is necessary to lubricate the key components in the reducer, including oil seals, bearings, gears, splines, etc. In the existing reducer, it mainly relies on the shaft and gear cooperating to rota...

Problems solved by technology

[0005] The embodiment of the present invention aims at the problem that the lubricating oil hardly reaches the lip of the oil seal when the input shaft rotates at a high speed for the above-mentioned reducer, which leads to the problem that the heat generated by the friction of the oil seal cannot be dissipated in time, and provides a reducer housing and a reducer
