Problems solved by technology

[0002] The harmonic reducer is a high-precision reducer, which is mostly used in high-precision instruments. The accuracy of the harmonic reducer will directly affect the accuracy of the instrument. During the operation of the harmonic reducer, the rigid wheel and the flexible The teeth of the wheel will inevitably produce friction and wear, and the current harmonic reducer does not have a good lubrication effect. The most direct impact of friction and wear on the teeth of the rigid wheel and the flexible wheel is to increase the backlash of the rigid wheel and the flexible wheel. Reduce the precision of the reducer and cause the reducer to vibrate during operation, so that the harmonic reducer cannot meet the high precision requirements
Although the commonly used grease lubrication can reduce friction and wear to a certain extent, the lubrication effect is not good and there is still much room for improvement.

Abstract

The invention discloses a forced oil lubrication harmonic reducer and a method thereof. The forced oil lubrication harmonic reducer structurally comprises a harmonic reducer body, a threaded pipe joint, an oil conveying hose, an oil tank and an oil pump, the harmonic reducer body comprises a rigid wheel, a soft wheel and a wave generator, the outer ring of the rigid wheel is provided with two symmetrical threaded holes for being connected with the oil conveying hose, lubricating oil in the oil tank enters a sealing cavity formed by the rigid wheel and the soft wheel and the overall cavity is filled with the lubricating oil during running of the oil pump, continuous lubrication between inner teeth of the rigid wheel and outer teeth of the soft wheel is realized, frictional wear of the innerteeth of the rigid wheel and the outer teeth of the soft wheel can be reduced, temperature rise of the harmonic reducer is reduced, and the service life of the harmonic reducer is prolonged.

Description

technical field [0001] The invention relates to the field of harmonic reducers, in particular to a forced oil lubricated harmonic reducer and a method thereof. Background technique [0002] The harmonic reducer is a high-precision reducer, which is mostly used in high-precision instruments.
