Method for eliminating three-ring speed reducer gear engagement impact

Abstract

The invention discloses a method for eliminating the gear engagement impact of a three-ring gear reducer. The method comprises the steps of drawing a mechanism principle graph of the engagement course of an inner toothed ring plate and an outer toothed ring plate according to the dimensions and position relation of the three-ring gear reducer; finding out the engagement region of the inner toothed ring plate and the outer toothed ring plate on the mechanism principle graph; determining the dead centre position of the engagement of the inner toothed ring plate and the outer toothed ring plate; calculating the corresponding angle of the engagement of the inner toothed ring plate; and repairing inner teeth of the corresponding angle of the engagement region of the inner toothed ring plate. The method has the advantages that the impact of the three-ring gear reducer generated by engaging force is eliminated or reduced; dead centre impact of mechanism is effectively reduced through the repair of the engagement region of the dead centre position of the inner toothed ring plate; the operation is stable; the impact vibration is reduced; the transmission speed ratio of the mechanism is not affected; the service life of a bearing is prolonged by 40 percent; and the service lives of sealing parts in the gear reducer are also prolonged. The three-ring gear reducer has less noise, thereby reducing noise pollution and improving working environment.

Description

technical field [0001] The invention relates to a method for eliminating the gear meshing impact of a three-ring reducer. Background technique [0002] figure 1 It is the top view of the whole section of the three-ring reducer; figure 2 yes figure 1 One of the internal gear ring plate transmission schematic diagram. [0003] Such as figure 1 As shown, the structure of the three-ring reducer includes: a box body 7; two parallel first high-speed shafts 2 and a second high-speed shaft 6 each with three eccentric shaft diameters are arranged in the box body; assembled on the first high-speed shaft 2 and the second high-speed shaft 6 three inner ring plates 1a, 1b, 1c with inner tooth planetary gears at the three eccentric shaft diameter positions; External gear 5. The phase differences of the three eccentric shaft diameters on the first high-speed shaft 2 and the second high-speed shaft 6 are all 120°; Shaft 2 and 2nd high speed shaft 6. The outer gear wheel 5 is fixedl...

Problems solved by technology

At the positions of 0° and 180°, both the inner gear ring plate and the outer gear are affected by the meshing force. At the moment of crossing the dead point, due to the influence of the meshing force, the three-ring mechanism itself will produce a large instantaneous impact, and the dead point position The meshing gear teeth will bear the impact of the mechanism, and the impact force will cause the three-ring mechanism to generate great vibration during operation, causing vibration to the arm bearing and other bearing bearings, which directly affects the service life of the bearing; the mechanism's The meshing impact also greatly increases the noise generated during the operation of the mechanism, causing environmental pollution
