Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a tooling for replacing the oil seal of a speed reducer. Background Technology

[0002] A speed reducer, also known as a geared motor, is a relatively precise mechanical transmission device. Its main function is to convert the high speed of a power source such as a motor to a suitable low speed by changing the transmission ratio, while simultaneously increasing the output torque to meet the power requirements of various mechanical equipment. The oil seal is a crucial component of the speed reducer; it's a device used to seal the gap between the speed reducer's rotating shaft and the housing. Its main function is to prevent lubricating oil leakage and to prevent external dust, moisture, and other impurities from entering the speed reducer.

[0003] In existing technology, a skeleton oil seal with elastic components is generally inserted into the housing of the reducer, and then a snap ring is inserted into the housing to restrict the position of the skeleton oil seal. This often requires technicians to replace the skeleton oil seal by gradually disassembling the reducer from the bottom. However, this method is not only time-consuming and labor-intensive, but also requires a lot of human resources and increases production costs. Utility Model Content

[0026] like Figures 1 to 3 The image shows a preferred embodiment of a tooling for replacing a gearbox oil seal. The gearbox includes a housing and a skeleton oil seal disposed within the inner cavity of the housing. The tooling includes: a clamping plate 100, with a first threaded hole in the middle and a notch 110 at both ends; two fasteners, each extending into a notch 110, the clamping plate 100 being detachably connected to the housing via the two fasteners; a first screw 200, connected to the clamping plate 100 via the first threaded hole, one end of the first screw 200 having a second threaded hole; and a pressure plate 300, connected to one end of the first screw 200, the pressure plate 300 being positioned opposite the skeleton oil seal. Furthermore, taking the reducer placed on a horizontal surface as an example, the cooperation of the clamping plate 100, the first screw 200 and the pressure plate 300 causes the skeleton oil seal to be pressed downward in the housing to separate from the snap ring, so that the snap ring is no longer tightly pressed by the skeleton oil seal. At this time, the snap ring can be disassembled first, and then the skeleton oil seal can be removed.

[0027] The upper end of the housing has several evenly distributed mating holes, and each fastener extends into one of the mating holes. The interior of the skeleton oil seal has an elastic component, which allows the top of the skeleton oil seal to move downward in the vertical direction when pressed. The inner wall of the housing has a groove that communicates with the inner cavity. A retaining spring is installed in the groove. The retaining spring has a ring structure and abuts against the upper end of the skeleton oil seal. The retaining spring is used to limit the upward displacement of the skeleton oil seal in the vertical direction.

[0028] Furthermore, as a preferred embodiment, the outer contour of the pressure plate 300 is smaller than the inner contour of the retaining ring.

[0029] Furthermore, as a preferred embodiment, it also includes: a bolt 400, a mounting hole on the pressure plate 300, the pressure plate 300 being detachably connected to the first screw 200 via the bolt 400, and one end of the bolt 400 passing through the mounting hole and threadedly connected to the second threaded hole.

[0030] Furthermore, as a preferred embodiment, the radial outer contour of the bolt head is larger than the inner contour of the mounting hole. This structure further facilitates the bolt 400 in securing the pressure plate 300 to the first screw 200.

[0031] Furthermore, as a preferred embodiment, the notch 110 is arranged in a U-shaped structure.

[0032] Furthermore, as a preferred embodiment, the radial outer contour of the fastener head is larger than the radial inner contour of the notch. Furthermore, this structure facilitates the fastener in securing the clamp 100 to the housing.

[0033] Furthermore, as a preferred embodiment, the fastener is preferably a fastening screw.

[0034] Furthermore, as a preferred embodiment, a protrusion 210 is provided at the other end of the first screw 200, and an external tool drives the rotation of the first screw 200 through the protrusion 210.

[0035] Furthermore, as a preferred embodiment, it also includes: two pull rods 500, both of which are detachably connected to the skeleton oil seal.

[0036] Furthermore, in a preferred embodiment, each pull rod 500 includes a connecting portion 510 and a second screw 520, one end of the second screw 520 being detachably connected to the skeleton oil seal, and the other end of the second screw 520 being connected to the connecting portion 510. Further, the skeleton oil seal has several threaded through holes, and each second screw 520 extends into one of the threaded through holes.

[0037] Furthermore, as a preferred embodiment, the connecting portion 510 is arranged in a circular structure. Furthermore, the circular structure makes it easier for the operator to turn the lever 500.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model.

[0039] Based on the above, this utility model also has the following embodiments:

[0040] In a further embodiment of this utility model, the first screw 200 and the second screw 520 are preferably made of steel.

[0041] In a further embodiment of this utility model, the pressure plate 300 is preferably made of iron.

[0042] In a further embodiment of this utility model, the connection between the connecting part 510 and the second screw 520 is preferably welded.

[0043] The specific operating steps of the tooling for replacing the oil seal of a speed reducer according to this utility model are as follows:

[0044] First, the operator places the reducer on a horizontal surface and connects the clamping plate 100, the first screw 200, the pressure plate 300, and the bolts 400. Then, the clamping plate 100 is fixedly mounted on the housing. The operator passes the fasteners through the notch 110 and screws them into the mating holes on the housing, thus fixing the clamping plate 100 to the housing. Next, the operator turns the first screw 200, causing it to move downwards and pull the pressure plate 300 downwards. At this point, the pressure plate 300 presses against the upper end of the oil seal skeleton, causing the oil seal skeleton to move downwards under pressure and gradually move away from the retaining ring. Then, the operator uses an external tool to remove the retaining ring from the inner cavity. Next, the operator removes the fasteners and removes the pressure plate 300 from the inner cavity of the housing. Subsequently, the operator screws the pull rod 500 into the threaded through hole on the oil seal skeleton and removes the oil seal skeleton from the inner cavity as a whole by applying force to the pull rod 500. Finally, the operator replaces the oil seal skeleton.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
