Problems solved by technology

The success rate of assembling the rollers by smearing grease is low, and the rollers may fall off if the operator is not careful when assembling the outer ring. If too much grease is applied, the grease cannot be quickly removed, and the clutch shaft may be blocked. The lubricating oil through hole on the surface affects the rotation flexibility of the roller and the cage, which greatly reduces the stability and reliability of the product.

Embodiment Construction

[0020] As shown in the figure, the assembly method of the roller overrunning clutch includes the following steps:

[0021] 1. Assemble the cage to the clutch shaft, and then install the assembly tool of the roller overrunning clutch from the small end of the clutch shaft;

[0022] 2. Install all the rollers in the semicircle of the assembly tool, and use the assembly tool as a guide to assemble the rollers, so that each roller can stay stably in the space formed by the semicircle, the cage and the groove of the clutch shaft;

[0023] 3. Install the outer ring;

[0024] 4. Withdraw the assembly tool from the small end of the clutch shaft to complete the assembly of the roller overrunning clutch.

[0025] The assembly tool of the roller type overrunning clutch includes a fork 1 and a handle 2. The fork 1 is cylindrical in shape, and the bottom of the cylinder is provided with a threaded hole for assembling the handle 2. The cylindrical The depth of the shift fork 1 is greater ...

Abstract

The invention relates to an assembling method of a roller type overrun clutch. The assembling method comprises the following steps: putting a roller in a semi-arc on a special tool by designing the special tool; guiding the roller to a mounting position through a tool; and then mounting an outer ferrule to finish assembly. In the assembling process, under the action of the semi-arc, the roller will not fall, so that the roller is mounted conveniently and rapidly; meanwhile, during mounting, lubricating oil is not used, so that the blocking phenomenon is avoided, the rotating flexibility of theroller and a retaining rack is guaranteed, and therefore, the using stability and reliability of a product are further guaranteed.

Description

technical field [0001] The invention relates to an assembly method of a roller type overrunning clutch, which can realize fast and simple assembly in the roller type overrunning clutch. Background technique [0002] The typical structure of the roller overrunning clutch is as follows: figure 1 and figure 2 As shown, it includes the clutch shaft 11, roller 12, and outer ring 13. In order to ensure that the rollers 2 enter and exit synchronously, a cage 14 is used to control the angular position of the rollers 12 on the clutch shaft 11 to be evenly distributed. At present, it is used for roller assembly of overrunning clutch, mainly by applying grease on the outer surface of the roller to make the roller stick to the clutch shaft, and then inserting it into the outer ring to realize the assembly of the clutch roller. The success rate of assembling the rollers by smearing grease is low, and the rollers may fall off if the operator is not careful when assembling the outer rin...
