Abstract

The invention discloses a large coupling. The large coupling comprises an inner shaft; an inner shaft sleeve is arranged on the outer side of the inner shaft; a main body front end is arranged on the outer side of an outer shaft sleeve; a main body front cover and a back cover are respectively arranged on two sides of the main body front end; a front end c over is arranged on the outer side of the main body front cover; outer shells are fixedly arranged on the main body front end and on the outer sides of the main body front cover and the back cover through fixed pieces; the main body front end and the other end of the main body front cover are fixedly arranged on the inner shaft sleeve through fixed pieces; and the other end of the back cover is fixedly arranged on the inner shaft through a fixed piece. The large coupling has the following advantages: the capability of compensating deviation of two shafts is achieved; the vibration of a mechanical transmission system is reduced; the impact peak load is reduced; the buffer vibration reducing performance is achieved; the overload protecting effect is achieved; and high-torque transfer can be realized.

Description

technical field

[0001] The invention relates to the technical field of transmission couplings, in particular to a large shaft coupling. Background technique

[0002] When the shafts are to be connected to transmit power, they are generally connected by pulleys or gears, but if the two shafts are required to be in a straight line and rotate at a constant speed, they must be connected by a coupling. The large shaft coupling in the prior art has short service life, poor buffering and vibration absorption performance, no overload protection function, difficult installation and alignment, and easy damage to the bearing. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a motor that has the ability to compensate for the offset of two axes, reduces the vibration of the mechanical transmission system, reduces the impact peak load, has cushioning and shock absorption performance, has an overload protection function, and can...

Embodiment Construction

[0016] When implementing it:

[0017] Such as figure 1 As shown, a large shaft coupling includes an inner shaft 7, an inner shaft sleeve 10 is arranged outside the inner shaft 7, a front end 4 of the body is arranged outside the outer shaft sleeve, and a front cover 2 and a rear body are respectively arranged on both sides of the front end 4 of the body. Cover 6, the front end cover 1 is arranged on the outside of the front cover 2 of the body, the front end 4 of the body, the front cover 2 of the body and the rear cover 6 are fixed with a housing 5 through the fixing part 3; the front end 4 of the body and the front cover of the body The other ends of 2 are all fixedly arranged on the inner shaft sleeve 10 through the fixing piece 3 , and the other end of the rear cover 6 is fixedly arranged on the inner shaft 7 through the fixing piece 3 . By fixing the front end 4 of the main body on the inner shaft sleeve 10 through the fixing piece 3, the function of shock absorption can...
