Abstract

The invention discloses a high-efficiency rzeppa constant velocity universal joint. The high-efficiency rzeppa constant velocity universal joint mainly comprises a bell-shaped shell, a star-shaped sleeve, a retainer, steel balls, an inner side, an opening side, ball ways A and ball ways B. The multiple ball ways extending in the axial direction are formed in the inner spherical surface of the bell-shaped shell, and the opening side and the inner side which are separated in the axial direction are arranged. The multiple ball ways paired with the ball ways of the bell-shaped shell are formed inthe outer spherical surface of the star-shaped sleeve. The multiple steel balls are clamped between the ball ways of the bell-shaped shell and the ball ways of the star-shaped sleeve and transmit torque. The steel balls are retained through the retainer. The retainer is provided with an outer spherical surface and an inner spherical surface which are matched with the inner spherical surface of thebell-shaped shell and the outer spherical surface of the star-shaped sleeve. According to the high-efficiency rzeppa constant velocity universal joint, the ball ways A and the ball ways B are arranged, so that the ball ways B do not generate offset distance, and therefore the axial force generated by the whole to the steel balls is reduced, the spherical surface friction abrasion of the retainer,the bell-shaped shell and the star-shaped sleeve is reduced, heating is reduced, and the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of constant velocity universal joints, in particular to a high-efficiency cage-type constant velocity universal joint. Background technique [0002] The existing fixed end ball cage type constant velocity universal joint mainly has the following structure: a bell-shaped shell 1, the inner spherical surface of which is formed with a plurality of ballways extending in the axial direction, and has an opening side 6 separated in the axial direction and the inner side 5; star-shaped sleeve 2, which forms a plurality of ballways paired with the ballway of the bell-shaped shell 1 on the outer spherical surface; a plurality of steel balls 4, which are sandwiched between the ballway of the bell-shaped shell 1 and the star-shaped sleeve 2 The cage 3, which holds the steel ball 4, has an outer spherical surface and an inner spherical surface that cooperate with the inner spherical surface of the bell shell 1 and the outer spheri...
