Problems solved by technology

[0002] In the connection of the left and right half-couplings, there are often requirements for coaxiality. At present, the measures for ensuring the coaxiality of the left and right half-couplings mainly include centering tenon and dynamic fit, etc. The repeated use of the centering tenon often causes wear , so as to lose the centering effect; dynamic fit, one is to increase the manufacturing cost of the left and right half couplings, and the second trial often produces impact during use

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] A coupling, including a left half coupling 1 and a right half coupling 2, characterized in that: the left half coupling 1 is provided with a boss 101, and the right half coupling 2 is provided with a The coupling boss 101 fits into the groove 201 .

[0016] further:

[0017] The above-mentioned coupling is characterized in that: the boss 101 of the left half coupling is a cone, and the groove 201 of the right half coupling is a tapered hole.

[0018] The frustum and cone hole have a guiding effect and are easy to process.

[0019] The above-mentioned coupling is characterized in that: the taper of the frustum and the taper hole is 12-18°.

[0020] The above-mentioned coupling is characterized in that: the taper of the frustum and the taper hole is 15°.

[0021] The above-mentioned coupling is characterized in that: the height of the frustum is 3-8mm.

Abstract

The invention relates to a coupling, which comprises a left half coupling and a right half coupling. The coupling is characterized in that: the left half coupling is provided with a boss, and the right half coupling is provided with a socket which is matched with the boss of the left half coupling. Since the boss and socket matching form is adopted by the coupling, the coupling is easy to center and assemble, the fitting surface is big, abrasions cannot be easily produced, moreover, the coupling is easy to manufacture, the cost is low, and the requirement of the coaxiality of the left half coupling and the right half coupling can be effectively ensured.

Description

technical field [0001] The invention relates to a shaft coupling, which belongs to the technical field of machinery. Background technique [0002] In the connection of the left and right half-couplings, there are often requirements for coaxiality. At present, the measures for ensuring the coaxiality of the left and right half-couplings mainly include centering tenon and dynamic fit, etc. Repeated use of the centering tenon will often cause wear , thus losing the centering effect; dynamic fit, one is to increase the manufacturing cost of the left and right half couplings, and the second trial often produces impact during use. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a shaft coupling, which adopts the form of cooperation between the boss and the groove, which is easy to assemble in the center, has a large matching surface, is not easy to wear, and at the same time is simple in manuf...
