Problems solved by technology
[0002] The existing ball cage synchronous universal couplings are mostly fixed on the outer rings at both ends of the ball cage coupling when in use, and cannot be fixed in the middle of the ball cage coupling, and auxiliary support cannot be added; at the same time, if the ball cage The coupling is long, the working speed exceeds its own limit speed, and cannot run at high speed; on the other hand, the existing ball cage synchronous universal coupling has only two joints and can only compensate for one angle

The invention discloses a synchronous universal coupling with three middle-supporting type ball cage joints, which is used for the field of special engineering vehicles and other engineering. The synchronous universal coupling consists of the three ball cage joints. In the synchronous universal coupling, a middle supporting device with a bearing is arranged on the excircle of a middle shaft head, the rotating direction and the jumping angles of a vehicle can be compensated simultaneously, two different angle compensations can be met by two different stretching amounts, the limiting rotating speed of the coupling is improved, and the diversity of the fixed modes of the ball cage coupling is realized, so that the ball cage coupling has a wider application range and field; and simultaneously, due to the function of using one set of ball cage coupling to replace two sets of ball cage couplings (4 joints), more installation space is saved, and the cost for manufacture, installation and maintenance is reduced.
Description
technical field [0001] The invention relates to a shaft coupling of a mechanical coupling device, in particular to a synchronous universal shaft coupling with intermediate support type three spherical cage joints used on special engineering vehicles. Background technique [0002] The existing ball cage synchronous universal couplings are mostly fixed on the outer rings at both ends of the ball cage coupling when in use, and cannot be fixed in the middle of the ball cage coupling, and auxiliary support cannot be added; at the same time, if the ball cage The coupling is long, and its operating speed exceeds its own limit speed, so it cannot run at high speed; on the other hand, the existing ball cage synchronous universal coupling has only two joints and can only compensate for one angle. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a three-spherical cage with intermediate support...
