Description

Technical Field

[0001] The utility model belongs to the field of high-speed conductive slip ring electrical connectors, and particularly relates to an anti-loosening coupling mechanism driven by a high-speed conductive slip ring electrical connector. Background Art

[0002] A high-speed conductive slip ring electrical connector is a signal transmission device for measuring physical parameters such as stress, temperature, vibration, and torque of a rotating part and monitoring its state. At present, high-speed slip ring electrical connectors are mainly used in the development and equipment testing of aerospace engines, aviation engines, high-speed transmission equipment, etc., and mainly transmit signals including power current, voltage, temperature, stress, pressure, digital signals, etc. During the test, the change in the resistance of the strain gauge caused by the deformation of the test part is very small, which requires minimizing or eliminating the contact resistance of the high-speed conductive slip ring electrical connector and making it stable. Since the test signal is carried out at a high rotational speed, that is, the coaxiality between the high-speed conductive slip ring electrical connector and the driving main shaft during installation is required to be very high. Poor installation of the high-speed conductive slip ring electrical connector will result in inaccurate test signals or directly damage the high-speed conductive slip ring electrical connector, etc. Therefore, the installation requirements are very high and the operation is inconvenient. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an anti-loosening coupling mechanism driven by a high-speed conductive slip ring electrical connector, which brings guarantee for the use of the high-speed conductive slip ring electrical connector and is flexible in use, and can meet the functions of different working conditions.

[0004] The above technical purpose of the utility model is achieved by the following technical solutions: an anti-loosening coupling mechanism driven by a high-speed conductive slip ring electrical connector, including a driving main shaft, one end of the driving main shaft is provided with an anti-loosening component, a hexagonal coupling is arranged between the driving main shaft and the anti-loosening component, both ends of the hexagonal coupling penetrate into the driving main shaft and the anti-loosening component respectively, the anti-loosening component includes a screw sleeve, a clamping sleeve is fixedly installed inside the screw sleeve, a hexagonal shaft sleeve is fixedly installed inside the clamping sleeve, and a spiral elastic retaining ring is arranged at one end inside the screw sleeve.

[0005] Adopting the above technical solution: When using this anti-loosening component, first, the high-speed wire slip ring electrical connector and the bushing are fastened through threaded connection. The rotating main shaft fits with the hexagonal shape at one end of the hexagonal coupling, realizing the coaxial drive rod between the rotating main shaft and the hexagonal coupling, where the rotating main shaft is connected to an external rotating structure. The hexagonal shape at the other end of the hexagonal coupling fits with the hexagonal bushing, so that the rotation of the hexagonal coupling will synchronously drive the hexagonal bushing and the bushing to rotate, thereby realizing the drive of the high-speed wire slip ring electrical connector. The material of the hexagonal coupling is selected as engineering plastic, which can ensure a certain strength of the hexagonal coupling and cannot transmit the interference signal of the rotating main shaft to the high-speed conductive slip ring electrical connector through the hexagonal coupling, resulting in interference to the signal test by the interference source, making the test signal unstable or even inaccurate, providing guarantee for the use of the high-speed conductive slip ring electrical connector. And this anti-loosening component has the advantages of simple installation operation and low debugging requirements. During use, according to the requirements of customers, without replacing the rotating main shaft, anti-loosening components of different sizes can be used to meet the needs of customers using different models of high-speed conductive slip ring electrical connectors. Also, without replacing the anti-loosening component, the operating conditions of customers can be achieved by changing the hexagonal coupling. Without changing the ferrule, pin rod, and spiral circlip, only by changing the thread size of the bushing, the hexagonal size of the hexagonal bushing and the hexagonal coupling can meet the different operating conditions of customers or replace different models of high-speed conductive slip ring electrical connectors. During the screwing of the thread between the bushing and the high-speed conductive slip ring electrical connector, a certain pre-tightening force is applied to the angular contact ball bearing in the high-speed conductive slip ring electrical connector, and then self-locking is completed by the ferrule. And the hexagonal coupling makes the rotating main shaft and the high-speed conductive slip ring electrical connector form an elastic connection, compensating for the coaxiality between the two, making the installation of the electrical connector simple and reducing the debugging requirements.

[0006] The present utility model is further arranged such that the material of the hexagonal coupling is engineering plastic, and both ends of the hexagonal coupling are hexagonal designs.

[0007] Adopting the above technical solution: The material of the hexagonal coupling is selected as engineering plastic, which needs to ensure a certain strength of the hexagonal coupling and cannot transmit the interference signal of the rotating main shaft to the high-speed conductive slip ring electrical connector through the hexagonal coupling, resulting in interference to the signal test by the interference source, making the test signal unstable or even inaccurate.

[0008] The present utility model is further arranged such that one end of the anti-loosening component is provided with a high-speed wire slip ring electrical connector penetrating into the interior of the bushing.

[0009] Adopting the above technical solution: Through the penetration of the high-speed wire slip ring electrical connector, the high-speed wire slip ring electrical connector and the bushing are connected and installed.

[0010] The present utility model is further arranged such that the high-speed wire slip ring electrical connector and the bushing are threadedly connected to each other.

[0011] With the above technical solution: The fastening between the high-speed wire slip ring electrical connector and the bushing is achieved through threaded connection.

[0012] The present utility model is further configured such that one end of the hexagonal coupling shaft is provided with a pin bar located inside the ferrule.

[0013] With the above technical solution: The pin bar is used in cooperation with the anti-loosening component.

[0014] The present utility model is further configured such that the hexagonal bushing is sleeved on the surface of the hexagonal coupling shaft, and the inner diameter of the hexagonal bushing fits the hexagonal shape at one end of the hexagonal coupling shaft.

[0015] With the above technical solution: The hexagonal shape of the hexagonal bushing and the hexagonal shape at one end of the hexagonal coupling shaft facilitate the coaxial rotation of the hexagonal coupling shaft driving the hexagonal bushing.

[0016] The present utility model is further configured such that the spiral elastic retaining ring is sleeved on the surface of the hexagonal coupling shaft and is mutually clamped with the bushing.

[0017] With the above technical solution: The spiral elastic retaining ring is used in cooperation with the hexagonal coupling shaft.

[0018] In summary, the present utility model has the following beneficial effects:

[0019] 1. For the anti-loosening component of the present utility model, through the engineering plastic material of the hexagonal coupling shaft, it can ensure a certain strength of the hexagonal coupling shaft, and at the same time, it will not transmit the interference signal of the driving main shaft to the high-speed conductive slip ring electrical connector through the hexagonal coupling shaft, thereby causing the signal test to be interfered by the interference source, making the test signal unstable or even inaccurate, providing a guarantee for the use of the high-speed conductive slip ring electrical connector.
