Problems solved by technology

A common feature of these connection methods is that they not only transmit the rotary motion, but also bear the axial force generated during the motion. They cannot be used in special occasions where the transmission of axial force is not allowed.

Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention will be further described

[0025] A shaft coupling with a cage that does not generate axial force according to the present invention has a structure as shown in Figure 1, which consists of an inner shaft 1, a left end cover 2, a screw 3, a steel ball 4, a transmission sleeve 5, and a right end cover 6 and cage 7 etc. are formed. Six uniformly distributed arc grooves with a diameter of ΦA are machined on the ΦC cylindrical surface of the inner shaft 1. The axis center of the arc groove ΦA is located on the cylindrical surface with a diameter of ΦB, and ΦB is greater than ΦC, so that the ΦB of the inner shaft 1 A cage 7 of graded steel balls is installed between the outer cylindrical surface and the ΦD inner cylindrical surface of the drive sleeve 5 . In the ΦD hole of the transmission sleeve 5, ΦA circular arc grooves with the same size, quantity, radial and circumferential distribution as the inner ...

Abstract

The invention relates to the field of mechanical transmission, relates to a technology for transmitting power between two concentric shafts, and particularly discloses a coupler with a retainer and without generating axial force. The coupler is composed of an inner shaft, a left end cover, a screw, a steel ball, a transmission sleeve, a right end cover and the retainer; and in mechanical transmission, the coupler is used for transmitting circumferential movement and torque between the two concentric shafts, and due to the fact that the steel ball is used for transmitting the circumferential movement and the torque, the axial force generated in the using process is very small and can be ignored in general using occasions, so that the coupler can be called as a coupler which does not generate the axial force. The coupler is particularly suitable for special occasions where the axial force is not allowed to be transmitted when the circumferential movement and the torque are transmitted.

Description

Technical field: [0001] The invention relates to the field of mechanical transmission, the technology for power transmission between two concentric shafts, in particular to a shaft coupling with a cage that does not generate axial force. Background technique: [0002] In mechanical transmission, there are many methods for connecting and transmitting power between two concentric shafts, such as spline connection, key (mainly refers to flat key) connection, interference connection, pin connection, thread connection, cone connection, plum blossom elastic Coupling connection, sleeve coupling connection, flange coupling connection, elastic coupling connection, etc. A common feature of these connection methods is that they not only transmit the rotary motion, but also bear the axial force generated during the motion, and cannot be used in special occasions where the axial force is not allowed to be transmitted. To this end, a coupling with a cage that does not generate axial forc...
