Oil seal press-fitting device for driving gear of speed reducer

Abstract

The invention provides an oil seal press-fitting device for a driving gear of a speed reducer. The oil seal press-fitting device comprises a press-fitting unit and a tightening unit, wherein the press-fitting unit comprises a bottom plate; two upright posts are fixedly connected onto the bottom plate; the upper ends of the upright posts are connected by a beam; a press-fitting power source is arranged on the beam; an oil seal pressure head is fixedly connected below the press-fitting power source; the tightening unit comprises a sleeve and two supporting arms, wherein the lower ends of the supporting arms are fixedly connected onto the bottom plate; a U-shaped slot tightening limiting block with an upward opening is arranged on each of the two upper ends of the supporting arms; limiting rods are transversely arranged at the outer periphery of the sleeve; the limiting rods are arranged in the U-shaped slots; a rotary shaft is sleeved in the sleeve; and a shaft hole which is matched with a drive gearing shaft is formed in the lower end surface of the rotary shaft. The oil seal press-fitting device for the driving gear of the speed reducer can be used for carrying out sealing sleeve radial jumping detection and oil seal sealing ring press-fitting on the same station, so that the quality of the driving gear is ensured, the transporting process is reduced, the labor intensity of a worker is reduced and the production efficiency is improved. Moreover, the oil seal press-fitting device has the advantages of being accurate in positioning, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to an oil seal press-fitting device, in particular to a device for press-fitting an oil seal sealing ring of a drive gear of a reducer. Background technique [0002] In the rear main reducer assembly, an oil seal ring is installed on the driving gear to seal the driving gear. The lubricating oil of the internal gears will not flow out to the outside world, and the sundries from the outside world will not enter the reducer and affect its internal environment. However, in the prior art, the press-fitting of the oil seal ring has the problem of cumbersome operations, as follows: [0003] 1. Due to the limitations of the layout and process of the existing assembly line, the main teeth need to be disassembled and assembled repeatedly. This process may easily cause the main teeth to be damaged or bumped during the disassembly process, which seriously affects the product quality and causes the failure of the assembly performance; [00...

Problems solved by technology

However, in the prior art, the press-fitting of the oil seal ring has the problem of cumbersome operations, as follows:

[0003] 1. Due to the limitations of the layout and process of the existing assembly line, the main teeth need to be disassembled and assembled repeatedly. This process will easily cause the main teeth to be damaged or bumped during the disassembly process, which will seriously affect the product quality and cause the failure of the assembly performance;

[0004] 2. This assembly method needs to move the disassembled reducer housing to the next station. The operation is cumbersome and the labor intensity is high.
