Problems solved by technology

The radial force generated by the rotating parts is borne by the rotating shaft bearing of the rotating connector itself, and the rotating shaft bearing of the rotating connector is generally narrow due to its size limitation and cannot bear a large radial force. Therefore, in the prior art When this kind of rotary connector is in use, the shaft bearings often appear to rotate unsmoothly due to the radial load, which affects the normal signal transmission. reduce

Embodiment Construction

[0014] Examples of swivel connectors are figure 2 As shown: the rotary connector in this embodiment is an electric rotary connector, including a support frame 9 and an adapter 1, and the support frame 9 is equipped with a rotating shaft 8 whose rotation axis extends in the front and rear direction through the rotating shaft bearing 7, and the support frame 9 The front end has a bearing installation sleeve 4, the rear end of the adapter 1 extends between the bearing installation sleeve 4 and the rotating shaft 8, the rear end of the adapter 1 is connected to the rotating shaft 8 through a key and a keyway structure 12, and the adapter 1 in the radial direction 1 is not in contact with the rotating shaft 8. The adapter 1 is rotatably assembled on the support frame through the adapter bearing 3. In this embodiment, the adapter bearing 3 is a double bearing structure located between the bearing mounting sleeve 4 and the rear end of the adapter. The inner wall of the bearing inst...

Abstract

The invention relates to a rotary connector. The rotary connector comprises a supporting frame and an adapter, a rotating shaft with the rotating axis extending in the front and back direction is rotationally assembled on the supporting frame through a rotating shaft bearing, the adapter is rotationally assembled on the supporting frame through an adapter bearing, and the adapter is connected with a rotating shaft in a standstill locking manner. The adapter is in rotary fit with the supporting frame through the adapter bearing, the adapter bearing singly bears the radial load or bears the radial load together with the rotating shaft bearing, the adapter is in standstill locking fit with the rotating shaft to transfer torque, and the matching relationship between the rotating shaft and the supporting frame does not need to be changed; and the appropriate adapter bearing is selected according to needs, and is not like the manner in the prior art that the radial load is only borne by the rotating shaft bearing, and the radial bearing capacity of the rotary connector is improved.

Description

technical field [0001] The invention relates to a rotary connector for signal transmission. Background technique [0002] The two parts that rotate relatively need to use the rotary connector during signal transmission, and the fixed part is connected with the supporting frame of the rotary connector, and the rotating part is connected with the rotating shaft of the rotary connector. For large-scale production, it is impossible to make a variety of rotary connector shafts. However, in actual use, the shapes of the rotating parts are different. Therefore, it is necessary to add an adapter between the rotating shaft and the rotating part to realize the connection between the rotating shaft and the rotating part. connect. The matching relationship between the adapter joint and the rotating shaft in the prior art is as follows: figure 1 As shown: the rotary connector includes a support frame 2 and a rotating shaft 5 whose rotation axis is rotatably assembled on the supporting ...
