Problems solved by technology

However, after the input shaft penetrates the star sleeve, the circlip at the shaft end opens to form a self-lock, and the input shaft and the star sleeve are connected as one, so the ball cage universal joint cannot be opened for normal half shaft repair, and only the assembly can be replaced. Parts, not only cause waste of materials, but also increase maintenance costs

Embodiment Construction

[0021] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.

[0022] Refer to attached figure 1 with figure 2 , The opening method of the self-locking half-axis ball cage universal joint, first determine the position of the outer raceway step 12. According to the groove on the end surface of the outer raceway 11 of the spherical cover 3, find the centerline A-C of the outer raceway, measure the length A-B (68mm) of the outer raceway with a measuring tool, and draw the upper end line B1- The length of B2 (40mm), measure the length B-C (15mm) of the lower platform on the centerline A-C of the outer raceway, connect B1 and C, B2 and C, draw the position of the lower platform 12 of the outer raceway, and use the slotted hole cutting tool along the The marked step line B1-C-B2 op...

Abstract

The invention discloses an opening method of a self locking half shaft rzeppa universal joint. The method includes the steps that a position of an outer roller path lower stand is determined and the outer contour line of the outer roller path lower stand is drawn; a slotted hole cutting opening tool is used for cutting slotted holes along the drawn outer contour line of the outer roller path lower stand, and the outer contour line of the outer roller path lower stand includes a lower stand line and a lower stand upper end line; the cut slotted holes are opened and through inside and outside; a special snap spring opening tool is used for dismantling a snap spring through the opened slotted holes. By means of the opening method of the self locking half shaft rzeppa universal joint, repairing and recycling of an assembly can be achieved, materials are saved to the maximum degree, and maintenance costs can be lowered.

Description

technical field [0001] The invention relates to a half-shaft ball cage universal joint, in particular to a method for opening a self-locking half-shaft ball cage universal joint. Background technique [0002] The half-axis spherical cage universal joint is a constant velocity universal joint. There are many types of constant velocity universal joints, among which the most widely used are "cage type constant velocity universal joints" and "tripod type constant velocity universal joints". This is mainly for the cage type constant velocity universal joint, which is mainly composed of bell housing, cage, steel ball, star sleeve, companion shaft (input shaft) and other main parts. The steel balls of this kind of ball cage are fixedly placed in the six windows of a cage between the star-shaped sleeve and the bell-shaped shell, and the steel balls are exactly half of the positions in the star-shaped sleeve and the bell-shaped shell. This is used to determine the angle of action w...
