Problems solved by technology

When the existing gears mesh with each other, due to problems such as manufacturing process or use wear, there is a gap between the teeth of the gears meshing with each other. In the actual transmission process, the defect of poor transmission stability may occur, and further There may be a collision between the teeth and the teeth, which will aggravate the wear of the teeth and generate noise
When the gear is used in an environment that needs to detect the rotation angle, the existence of the rotation gap affects the detection accuracy of the rotation angle

Abstract

The invention relates to the field of gear design, in particular to a gear assembly capable of eliminating transmission gaps. The gear assembly comprises a gear shaft, a first helical gear, a second helical gear, a spring and an adjusting mechanism. The gear shaft is sleeved with the first helical gear, and the first helical gear is in interference fit with the gear shaft. The gear shaft is sleeved with the second helical gear in a clearance fit mode. The spring and the adjusting mechanism are installed on the gear shaft. The spring is arranged between the second helical gear and the adjusting mechanism, one end of the spring is made to abut against the right end face of the second helical gear, and the other end of the spring is made to abut against the adjusting mechanism. According to the technical scheme, when the gears are meshed, the transmission gaps between gear teeth can be eliminated, in this way, transmission precision and stability are improved, meanwhile, the abrasion speed of the gear teeth is decreased, the service life of the gears is prolonged, and noise is lowered.

Description

technical field [0001] The invention relates to the field of gear design, in particular to a gear assembly capable of eliminating transmission gaps. Background technique [0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. Gears are toothed mechanical parts that can mesh with each other, and the application of gears in transmission has appeared very early. At the end of the 19th century, the principle of generative gear cutting method and special machine tools and cutting tools using this principle appeared one after another. With the development of production, the stability of gear operation was paid more attention. [0003] Existing gears usually include gear teeth, tooth grooves, and end faces. When the existing gears mesh with each other, due to problems such as manufacturing process or use wear, there is a gap between the teeth of the gears meshing with each other. In the actual transmission process, th...
