Embodiment 1

[0034] Embodiment 1: A structural design method of a high-strength cage for a cage-type constant velocity universal joint, which is carried out according to the following design method:

[0035] ①. Increase the width of the cage, that is, increase the dimensions A1 and A2:

[0036] Increase the size of A1, and A2 can ensure that the inner star wheel can be installed, that is, A1≠A2, and the dimensions of A1 and A2 are designed as follows:

[0037] A1=0.6~0.68*d

[0038] A2=0.5~0.55*d;

[0039] ②. Increase the width B of the window beam, and design four small and two large window holes, that is, reduce the dimensions L1 and L2:

[0040] L1 is enough to ensure that the inner star wheel can be installed, and L2 is enough to ensure that the steel balls have a rolling gap in the fairway. The dimensions of L1 and L2 are designed as follows:

[0041] L1=1.39~1.41*d

[0042] L2=1.26~1.27*d;

[0043] Around the L1 window hole, try to design a large round corner transition, the exp...

Abstract

The invention relates to a structural design method of a high-strength retainer, and particularly relates to a structural design method of a high-strength retainer for a ball cage type constant velocity universal joint. The design method comprises the following steps of increasing the width of a retainer, and namely increasing the sizes A1 and A2; increasing the width B of a window hole beam, designing four small window holes and two large window holes, and namely reducing the sizes L1 and L2; designing the diameter of the inner spherical surface of the retainer; and recommending interference fit between the retainer window holes and steel balls. The strength of the retainer is further improved, and the use safety performance is improved.

Description

technical field [0001] The invention relates to a structural design method of a high-strength cage, in particular to a structural design method of a high-strength cage for a ball cage type constant velocity universal joint. Background technique [0002] If the fixed-end spherical cage of ATV, UTV, etc. is designed according to the conventional design of the passenger car cage, it will often fail due to insufficient cage strength under severe working conditions. [0003] Chinese patent CN201720955700.5 discloses a beach wheel hub bearing. ATV bearings need to work in the presence of water, sand, stones, etc. External mud, sand, water, etc. can easily enter the interior of the bearing, resulting in bearing wear, short life, and high cost of use. The utility model is a beach wheel hub bearing, which includes an outer ring, an inner ring, steel balls and a cage. One end of the cage is provided with a conical protrusion, which is opposite to the rectangular protrusion of the inn...
