Embodiment 1

[0019] Such as figure 1 As shown, a ball cage type universal joint assembly process includes the following process steps:

[0020] (1) Install the outer cage 1: the length of the outer cage 1 is 156mm, first apply a small amount of cage oil on the raceways of the inner and outer cages, and then coat the wear-resistant inner shell 7 of the outer cage 1 with The chamfered side and the chamfered side of the ball cage are installed in the same direction, and the two are vertically loaded into the outer race 6, and six steel balls 8 are respectively installed on the ball cage at intervals, so that the ball cage, wear-resistant The inner shell 7 and the steel ball 8 are pushed into the outer race 6, the diameter of the steel ball 8 is 14.4 mm, so that the chamfered side of the wear-resistant inner shell 7 and the chamfered side of the ball cage face the outer seat The big end of ring 6, after installation, fill the ball cage with oil;

[0021] (2) Install the inner ball cage 2: th...

Embodiment 2

[0025] Example 2: The rest is the same as in Example 1, except that in the step (1), the length of the outer cage 1 is 159mm, and the diameter of the steel ball 8 is 14.8mm; in the step (2), the inner cage 2 The length is 156mm; in the step (3), the length of the outer cage dust jacket 3 is 161mm; the working temperature of the cage oil used in the step (1) is 70°C.

Embodiment 3

[0026] Example 3: The rest is the same as in Example 1, except that in the step (1), the length of the outer cage 1 is 165mm, and the diameter of the steel ball 8 is 15.6mm; in the step (2), the inner cage 2 The length is 162mm; in the step (3), the length of the outer cage dust jacket 3 is 167mm; the working temperature of the cage oil used in the step (1) is 100°C.

[0027] From the above examples, it can be known that this kind of ball cage universal joint assembly process enhances the wear resistance of the ball cage universal joint, makes the connection of each part more stable and reliable, and is not easy to break during use, and extends the life of the ball cage. The service life of the type universal joint.

Abstract

The invention discloses an assembly technology for a ball-cage universal joint. The technology relates to the technical field of ball-cage universal joints and comprises four technological courses including installation of an outer ball cage, installation of an inner ball cage, installation of an outer ball cage dust-proof sleeve and installation of a half shaft. According to the technological method, lithium base grease is adopted; and superior-level molybdenum disulfide is contained, so that wear resistance of the ball-cage universal joint is strengthened. During assembly of the universal joint, a clamping ring is used; the ball-cage dust-proof sleeve and an outer base ring are fixed by a large clamping hoop, so that connection among different parts becomes more stable, and fracture does not take place easily during use; the whole ball cage is divided into two parts through setting of a wear-resistant inner shell body, so that the universal joint has higher wear resistance when friction happens between the universal joint and other components during use, and the service life is prolonged; and the dust-proof sleeve of the outer ball cage is made of a mixture which comprises chloroprene rubber adhesive, nitrile-butadiene rubber, silica gel and plastic, so that the service life of the dust-proof sleeve of the outer ball cage can be increased.

Description

technical field [0001] The invention relates to the technical field of ball cage type universal joints, in particular to an assembly process of ball cage type universal joints. Background technique [0002] The ball cage universal joint is a part of the auto parts, mainly used for the indispensable transmission parts in the speed control system of the car, and plays an important role in the operation of the speed control system of the car. The current mechanical design of the ball cage type universal joint is unreasonable. The unreasonable design of the ball cage type universal joint for automobiles will also make the universal joint unreasonable. Time movement breaks. The application number is 201520213052.7, which discloses a fixed ball cage universal joint, including a drive shaft, an outer cover, an inner raceway and an outer raceway. The inner raceway is set in the outer raceway and fixed on the outer raceway through the outer cover. It passes through the outer cover ...
