A non-contact sealing structure of a reducer

Abstract

The invention provides a non-contact type sealing structure for a speed reducer and belongs to the technical field of sealing of the speed reducer. The non-contact type sealing structure for the speed reducer comprises an oil returning transparent cover, an oil slinger and a box body; a bearing sleeves a rotary shaft arranged at an opening of the box body, and a separation spring and the oil returning transparent cover sleeve the rotary shaft in sequence along a direction from an inner part to an outer part of the box body; the oil slinger is arranged in the oil returning transparent cover; the oil slinger also sleeves the rotary shaft; a gap of 0.5mm is formed between an inner wall of the oil returning transparent cover and an outer ring of the oil slinger, so that the whole oil returning transparent cover can be axially assembled on the opening of the box body; the non-contact type sealing structure is convenient to machine, a problem that splitting machining and assembling work are complicated is solved and leakage can also be effectively reduced; the oil returning transparent cover is provided with an oil returning groove and an oil collection groove, and the oil returning groove and the oil collection groove are connected with an oil returning hole in the box body, so that overflowed lubricating oil can be rapidly collected and recycled back to the box body; and the oil returning transparent cover can be smaller than the size of a splitting design and is convenient and applicable.

Description

technical field [0001] The invention relates to the technical field of reducer sealing, in particular to a non-contact sealing structure of a reducer. Background technique [0002] With the deepening of the concept of machine generation, the frequency of use of machinery and equipment in all walks of life is increasing. As the main component of machinery and equipment, the development of reducer has become the focus of people's attention. [0003] At present, although the frequency of use of the reducer is high, due to the lack of the mechanical seal structure commonly used in the reducer, the existing reducer still has the following problems: 1. The processing requirements are high and the processing technology is complicated; 2. The parts are large in size, 3. Poor sealing, slow oil return process, easy to cause accumulation and leakage of lubricating oil. Contents of the invention [0004] In view of the above-mentioned problems existing in the prior art, it is now int...
