Problems solved by technology

At present, the spacer for planetary cycloid reducer with this structure has the following defects: (1) poor wear resistance, high temperature resistance, poor use effect, high noise and short service life
The current spacer ring for planetary cycloid reducer is composed of an annular spacer ring body, and the end faces of both sides of the spacer ring body in contact with the cycloid wheel are large-area plane contacts, that is, the spacer ring body is a solid structure, This structure makes the end faces on both sides of the spacer ring fully contact with the cycloid wheel, there is no lubricating oil between the two, and it is in a dry grinding state. The temperature between the spacer ring and the cycloid wheel rises, and the end faces on both sides of the spacer ring are easily The wear resistance of the spacer ring is poor, it is not resistant to high temperature, the use effect is poor, the noise is large, and the service life is short; in addition, the material of the spacer ring body is made of cast iron, which also makes the heat transfer of the spacer ring fast, the temperature rises, and the wear resistance is poor. Poor effect, loud noise, short service life; (2) high cost, polluting lubricating oil
The existing spacer ring body is a solid structure, which leads to a large amount of material usage, which not only wastes materials, but also greatly increases the cost; in addition, the existing spacer ring body is made of cast iron, which is expensive, which also leads to the cost of the spacer ring. High; in addition, cast iron materials are easy to grind out iron ions, and will also pollute the lubricating oil in the transmission device. Dirty lubricating oil will not only lead to increased oil impurities and affect the lubrication effect and service life of the transmission parts in the transmission device, but also make the lubricating oil generally It needs to be replaced once in less than half a year, and sometimes it needs to be replaced in two or three months, which also leads to high cost
[0003] People have been exploring and researching spacers for planetary cycloid reducers that can make up for the above defects to meet the urgent needs of the market, but they have not been able to solve this technical problem.

Abstract

The invention relates to a cycloidal planetary gear speed reducer, and particularly relates to a spacing ring for a cycloidal planetary gear speed reducer. The spacing ring is composed of an annular spacing ring body (1); annular grooves (1-1) are arranged on left and right end faces of the spacing ring body (1), and an oil inlet opening (1-2) is arranged on the spacing ring body (1). The spacing ring has the following advantages: (1) by adopting the spacing ring, the two end surfaces of the spacing ring body are in small-area plane contact with a cycloidal gear, lubricating oil enters the annular groove through the oil inlet opening to cool and lubricate the spacing ring and the cycloidal gear; two end surfaces of the spacing ring are unlikely to wear; furthermore, the spacing ring is heat-resistant, good in using effect and noise reducing effect, low in noise, and long in service life; and in addition, as the spacing ring body is made of nylon, the spacing ring has a small thermal expansion coefficient and can play the action of resisting wear and inhibiting temperature rising. Besides, the spacing ring for the cycloidal planetary gear speed reducer is environmental-friendly, pollution-free, clean, energy-saving, low in cost and high in intensity.
