Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
As shown in Figure 1, Figure 2, Fig. 3, a kind of planetary reducer reducing output shaft axial float, including procapsid 110, output shaft
100, procapsid 110 integrally formed with circle end face 120, is offered close to 100 direction of output shaft on the inner wall of circle end face 120
Internal screw thread 240,100 surface of output shaft are socketed with the locking retaining ring 130 fixed with circle end face 120, the circumference of lock sleeve circle 130
Surface offers external screw thread 220, and the internal screw thread 240 that the external screw thread 220 of locking retaining ring 130 is tightened against circle end face 120 completes row
The compacting in star speed reducer gap between each part when assembling, the hollow space locked between retaining ring 130 and output shaft 100 are equipped with
The processing method of oil sealing 140, procapsid inner wall of the present invention can disposably become second nature, and meet the requirement of output shaft rigidity while also expiring
The foot requirement of concentricity.
In addition, the axle center of locking retaining ring 130 is identical with the axle center of output shaft 100, the height and locking gear of circle end face 120
