Series cycloidal gear reducer

Abstract

The invention relates to a serial connection type cycloid gear speed reducer, a tubular speed reducer for short. The advantages of cycloid gear engagement pairs are brought into full play. A high-speed shaft rotates by a circle, a low-speed shaft rotates by one tooth, and the speed ratio is low so that a machine body can be small. The three engagement pairs low in speed ratio are connected in series, the overall speed ratio is calculated according to the power three, and the good effect that the speed ratio is large while the size is small is achieved. A machine shell (K) is composed of a middle base (1), a left cover (2) and a right cover (3) which are connected through screws (4) to form the rigid shell. A first-level transmission assembly (J1), a second-level transmission assembly (J2) and a third-level transmission assembly (J3) are included. The tooth profile parameters of three levels of engagement pairs of the serial connection type cycloid gear speed reducer are completely the same, the three levels of engagement pairs are the same in radial size and center distance A, only the axial size is increased according to the stress conditions, and all components are installed in the tubular machine shell (K). The transmission ratio is large, the size is small, the weight is low, noise is avoided, and heating is not likely to happen. Meanwhile, efficiency is very high, ad work is reliable. The serial connection type cycloid gear speed reducer is suitable for being used under the special conditions that installing spaces for robots, mechanical arms and the like are narrow.

Description

technical field [0001] The invention relates to a tandem cycloidal gear reducer, which belongs to the tandem cycloidal gear reducer which can be referred to as a tubular reducer according to its shape characteristics in the field of mechanical transmission. technical background [0002] In the prior art, for reduction machinery under special conditions, involute gear reducers or cycloidal pinwheel reducers are generally used. However, these reducers inevitably have the following disadvantages: [0003] 1. Heat generation: increase the temperature of the lubricant, reduce the life of the bearing, and reduce the deceleration efficiency. [0004] 2. Noise: It affects the quiet environment of the operator and increases fatigue. [0005] 3. Larger volume: occupying the overall space of the machine. [0006] 4. Heavy weight: more metal materials are consumed. Contents of the invention [0007] In order to solve the above-mentioned problems, the present invention aims at the ...
