Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a shock-absorbing and highly responsive coupling. Background Technique

[0002] A coupling is used to connect a driving shaft and a driven shaft. Generally, one end is connected to a speed reducer, and the other end is used to connect a working element to transmit the power torque to drive the entire mechanism; the constituent materials include aluminum alloy, stainless steel, brass, etc.; it is widely used in equipment such as automobiles, industrial machinery, ships, and generators; common rigid couplings have characteristics such as light weight, ultra-low inertia, and high sensitivity, and the design is simple, making its manufacturing and installation processes relatively easy. However, in fields with high requirements for the transmission system, such as precision machinery, automation equipment, robots, etc., in these applications, rigid couplings cannot ensure that the equipment cannot absorb shocks and vibrations under high-speed, high-precision, and heavy-load conditions, affecting the stability of equipment operation; a rigid coupling is composed of rigid force-transmitting parts, and there is no relative movement between the connecting parts, so it does not have the ability to compensate for the relative offset of the two axes. This means that it has high requirements for the alignment of the two shafts. If there is skew or displacement between the two shafts, the rigid coupling cannot be effectively adjusted or compensated, which may lead to premature damage to the shaft, bearings, or the coupling itself; because the parts in the rigid coupling are all rigid and lack elastic elements, it does not have the ability to buffer and absorb vibrations. In the transmission system, if there are shocks or vibrations, these forces will be directly transmitted to the shaft, which may deteriorate the working conditions of the shaft, bearings, and parts on the shaft, and even cause additional stress, accelerating the wear and damage of the parts; in order to ensure the normal operation and extend the service life of the rigid coupling, it is necessary to strictly control the alignment accuracy of the two shafts. If the alignment accuracy of the two shafts is insufficient during installation, it will reduce the service life, transmission accuracy, and transmission efficiency of the coupling, and may cause vibrations and noises.

[0003] In view of the above-mentioned potential safety hazards, a shock-absorbing and highly responsive coupling is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shock-absorbing and highly responsive coupling to solve the problems in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a shock-absorbing and highly responsive coupling, including a first connecting shaft sleeve, a rubber connecting block, and a second connecting shaft sleeve;

[0007] Counterbore threaded holes are provided on the outer walls of one side of the first connecting shaft sleeve and the second connecting shaft sleeve, and a pair of perpendicular cutting grooves are also provided;

[0008] Both ends of the first connecting bushing and the second connecting bushing are provided with several protruding and mating supporting feet;

[0009] The rubber connecting block is provided with mounting grooves that cooperate with the supporting feet;

[0010] The first connecting bushing and the second connecting bushing tightly connect the rubber connecting block through the cooperation of the supporting feet and the mounting grooves, and are clamped by clamping screws.

[0011] Preferably, in one scheme, the inner diameter of the first connecting bushing is smaller than the inner diameter of the second connecting bushing.

[0012] Preferably, in one scheme, the number of the supporting feet is at least 3.

[0013] Preferably, in one scheme, the supporting feet are provided with connecting card slots.

[0015] Due to the application of the above technical solution, the beneficial effects of the present application compared with the prior art are as follows:

[0016] A shock-absorbing and high-response coupling of the present application, through the combined design of the first connecting bushing, the rubber connecting block and the second connecting bushing, the nearly integrated structure enables the shock-absorbing and high-response coupling of the present application to have an extremely fast response speed when transmitting power, and can quickly adapt to changes in the equipment speed and load.

At the same time, it also provides the function of electrical insulation, enhances the safety performance of the equipment, and can also be better applied to the electrical field.
