Description

Technical Field

[0001] The utility model belongs to the technical field of speed reducers and relates to a speed reducer, in particular to a gear speed reducer. Background Art

[0002] Oil leakage often occurs between the housing and the end cover of the existing gear reducer, and if the screws connecting the two are too long, they will press against the housing and cause oil leakage.

[0003] Therefore, the applicant designs a gear reducer with enhanced sealing performance between the housing and the end cover to solve the above problems. Summary of the invention

[0004] The utility model aims to provide a gear reducer with improved sealing performance in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: A gear reducer, including a housing and an end cover connected to the housing, characterized in that a sealing gasket is provided between the housing and the end cover, the housing and the end cover are connected by a plurality of screws passing through the sealing gasket, a plurality of avoidance grooves are opened on the housing, and an oil plug is provided on the end face of the housing.

[0006] In the above-mentioned gear reducer, the housing includes a connecting portion connected to the end cover, and the oil plug is arranged on the end surface of the connecting portion.

[0007] In the above-mentioned gear reducer, the inner wall of the end cover has a connecting rib with a notch, and the sealing gasket has a sealing clip and a portion that is clipped with both ends of the connecting rib.

[0008] In the above-mentioned gear reducer, there are seven screws.

[0009] In the above-mentioned gear reducer, there are four avoidance grooves.

[0010] Compared with the prior art, the gear reducer has the advantages of improving the sealing between the housing and the end cover and preventing oil leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the figure, 1. box body; 2. end cover; 3. sealing gasket; 4. screws; 5. avoidance groove; 6. oil plug; 7. connecting part; 8. connecting rib; 9. sealing card and part. DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3 As shown, the gear reducer includes a housing 1 and an end cover 2 connected to the housing 1, a sealing gasket 3 is provided between the housing 1 and the end cover 2, the housing 1 and the end cover 2 are connected by a plurality of screws 4 passing through the sealing gasket 3, a plurality of avoidance grooves 5 are opened on the housing 1, and an oil plug 6 is provided on the end surface of the housing 1.

[0017] In further detail, the housing 1 includes a connecting portion 7 connected to the end cover 2, and the oil plug 6 is arranged on the end face of the connecting portion 7. The oil plug 6 of the existing gear reducer is arranged on the peripheral wall of the connecting portion 7, and its sealing performance is not high and side leakage occurs. Now it is arranged on the end face, which improves the reliability of sealing and leakage detection.

[0018] To be more specific, the inner wall of the end cover 2 has a connecting rib 8 with a notch, and the sealing gasket 3 has a sealing clamping portion 9 clamped with both ends of the connecting rib 8, thereby improving the reliability of the installation of the sealing gasket 3.

[0019] To be more specific, there are seven screws 4, and increasing the number of screws 4 enhances the sealing strength.

[0020] To elaborate further, there are four avoidance grooves 5 , and four avoidance grooves 5 are added to prevent the screws 4 from being too long and pressing against the box body 1 to cause oil leakage.

[0021] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0022] Although this article uses more terms such as box body 1, end cover 2, sealing gasket 3, screw 4, avoidance groove 5, oil plug 6, connecting part 7, connecting rib 8, sealing card and part 9, it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
