Description

Technical Field

[0001] This utility model belongs to the field of gearbox technology, and in particular relates to a gearbox cover that improves the sealing effect. Background Technology

[0002] With the development of society, people are using more and more machinery. Therefore, in order to achieve high-performance operation of machinery, gearboxes play an important role. Gearboxes mainly have functions such as acceleration and deceleration (commonly known as speed change gearboxes), changing transmission direction, changing torque, clutch function, and power distribution. They are one of the essential parts of modern mechanical products.

[0003] Typically, a separate cover is installed in a closed structure for gearboxes. Multiple screw holes are usually provided on the surface of the cover, and screws are used to connect the cover to the gearbox body, ensuring a secure connection and preventing loosening. However, this installation method is cumbersome when the gears inside the gearbox need maintenance. The process of disassembling and reinstalling the cover requires tightening multiple screws, which is time-consuming and extends equipment downtime, thus affecting production efficiency. Therefore, we propose a gearbox cover with improved sealing performance. Utility Model Content

[0004] The purpose of this invention is to provide a gearbox cover with improved sealing performance. By setting a locking assembly, this fixing method replaces the traditional screw fixing, allowing for quick installation and removal of the cover to facilitate inspection, maintenance, or replacement of parts inside the gearbox. This improves maintenance efficiency, reduces equipment downtime, and helps ensure the continuity and stability of production. It solves the problem that existing methods connect the cover to the gearbox body with multiple screws, which require a long time to unscrew and reinstall the cover, thus extending equipment downtime and affecting production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a gearbox cover for improving sealing effect, including a cover, a shaft hole is opened on the side wall of the cover, a sealing ring is provided at the shaft hole, and a box body is provided on the back of the cover.

[0007] The gearbox cover is equipped with locking assemblies on both sides. Each locking assembly includes a pressure plate fixedly connected to the side wall of the gearbox cover. A lead screw is threaded onto the inner wall of the pressure plate. A limit ring is fixedly connected to the side of the lead screw closest to the gearbox body. A locking plate is rotatably connected to the outer surface of the limit ring. A fixing buckle is provided on the side of the locking plate closest to the gearbox body. The side of the fixing buckle furthest from the locking plate is fixedly connected to the outer surface of the gearbox body. Both the limit ring and the fixing buckle have beveled surfaces. When the locking plate contacts the surface of the fixing buckle connected to the side wall of the gearbox body, since both contact surfaces are beveled, as the locking plate moves towards the fixing buckle, the gearbox body moves towards the gearbox cover via the fixing buckle, thus locking the gearbox cover to the gearbox body. This fixing method replaces the traditional screw fixing, allowing for quick installation and removal of the gearbox cover for inspection, maintenance, or replacement of parts inside the gearbox, thereby improving maintenance efficiency, reducing equipment downtime, and ensuring the continuity and stability of production.

[0008] Furthermore, a throttle is fixedly connected to the end of the lead screw away from the locking plate, and a limit rod is fixedly connected to the side of the locking plate away from the housing. By setting the limit rod, the locking plate can maintain a stable movement trajectory when moving, thereby ensuring that the locking plate is engaged with the fixing buckle.

[0009] Furthermore, the end of the limiting rod away from the locking plate passes through the side wall of the pressure plate and extends to the outside. The outer surface of the limiting rod is slidably connected to the inner wall of the pressure plate. A support frame is fixedly connected to the side of the cover near the gearbox body. By setting the support frame, the transmission parts of the gearbox can be made more robust and stable.

[0010] Furthermore, a pressure ring is fixedly connected to the side of the lid near the box body, and a sealing ring is provided on the side of the pressure ring near the box body. The sealing ring is made of rubber and can deform under pressure, thereby better fitting and filling the gap between the lid and the box body.

[0011] Furthermore, the outer surface of the sealing ring is fixedly connected to the inner wall of the housing, and the surface of the sealing ring that contacts the pressure ring is a wedge-shaped inclined surface. A sealing ring is provided between the pressure ring and the sealing ring, and the outer surface of the sealing ring is fixedly connected to the side of the pressure ring near the sealing ring. Since the inclined surface has a certain guiding property, it is easier to align the housing cover when it is installed on the housing. Moreover, the wedge-shaped inclined surface will generate a certain squeezing effect, so that the pressure ring and the sealing ring can fit more tightly, thereby effectively preventing the leakage of lubricating oil or other media.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model features a locking assembly. Specifically, as the lead screw rotates, the locking plate is pushed towards the gearbox via a limiting ring. When the locking plate contacts the surface of the fixing buckle connected to the side wall of the gearbox, since both contact surfaces are inclined, the gearbox moves towards the cover via the fixing buckle as the locking plate continues to press and move towards the fixing buckle, thus locking the cover to the gearbox. This fixing method replaces the traditional screw fixing, allowing for quick installation and removal of the cover to inspect, repair, or replace parts inside the gearbox, thereby improving maintenance efficiency, reducing equipment downtime, and ensuring the continuity and stability of production.

[0014] 2. This utility model incorporates a pressure ring, specifically a sealing ring between the pressure ring and the sealing ring. The sealing ring is made of rubber and deforms as the pressure ring and sealing ring are squeezed together, thus better fitting the gap between them and increasing the sealing effect between the lid and the box body. The surface where the pressure ring and the sealing ring meet is a wedge-shaped slope. Due to the guiding nature of the slope, it is easier to align the lid when it is installed on the box body. The wedge-shaped slope also generates a certain squeezing effect, allowing the pressure ring and the sealing ring to fit more tightly, thereby effectively preventing the leakage of lubricating oil or other media.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-5 As shown, this utility model is a gearbox cover for improving sealing effect, including a cover 1, a shaft hole 102 is provided on the side wall of the cover 1, a sealing ring is provided at the shaft hole 102, and a box body 101 is provided on the back of the cover 1.

[0026] Locking assemblies 2 are provided on both sides of the lid 1. Each locking assembly 2 includes a pressure plate 201 fixedly connected to the side wall of the lid 1. A lead screw 202 is threadedly connected to the inner wall of the pressure plate 201. A limit ring 203 is fixedly connected to the side of the lead screw 202 closest to the box body 101. A locking plate 204 is rotatably connected to the outer surface of the limit ring 203. A fixing buckle 205 is provided on the side of the locking plate 204 closest to the box body 101. The side of the fixing buckle 205 furthest from the locking plate 204 is fixedly connected to the outer surface of the box body 101. Both the side of the limit ring 203 and the fixing buckle 205 that are close to each other are beveled. Specifically, by setting up the locking assembly 2, the locking mechanism works as the lead screw 202 rotates... The locking plate 204 is pushed towards the housing 101 by the limiting ring 203. When the locking plate 204 contacts the surface of the fixing buckle 205 connected to the side wall of the housing 101, since the contact surfaces of both are inclined, as the locking plate 204 moves towards the fixing buckle 205, the housing 101 moves towards the housing cover 1 through the fixing buckle 205, thereby locking the housing cover 1 and the housing 101. This fixing method replaces the traditional screw fixing, and the housing cover 1 can be quickly installed and removed to inspect, repair or replace parts inside the gearbox, thereby improving maintenance efficiency, reducing equipment downtime, and helping to ensure the continuity and stability of production.

[0027] A throttle 301 is fixedly connected to the end of the lead screw 202 away from the locking plate 204, and a limit rod 302 is fixedly connected to the side of the locking plate 204 away from the housing 101.

[0028] The end of the limiting rod 302 away from the locking plate 204 passes through the side wall of the pressure plate 201 and extends to the outside. The outer surface of the limiting rod 302 is slidably connected to the inner wall of the pressure plate 201. A support frame 303 is fixedly connected to the side of the box cover 1 near the box body 101.

[0029] A pressure ring 401 is fixedly connected to the side of the cover 1 near the box body 101, and a sealing ring 402 is provided on the side of the pressure ring 401 near the box body 101.

[0030] The outer surface of the sealing ring 402 is fixedly connected to the inner wall of the housing 101, and the surface where the sealing ring 402 and the pressure ring 401 meet is a wedge-shaped inclined surface.

[0031] A sealing ring 403 is provided between the pressure ring 401 and the sealing ring 402. The outer surface of the sealing ring 403 is fixedly connected to the side of the pressure ring 401 near the sealing ring 402. By setting the pressure ring 401, specifically the sealing ring 403 between the pressure ring 401 and the sealing ring 402, the sealing ring 403 is made of rubber. It can deform as the pressure ring 401 and the sealing ring 402 are squeezed against each other, thereby better fitting the gap between them and increasing the sealing effect between the cover 1 and the box body 101. The surface where the pressure ring 401 and the sealing ring 402 meet is a wedge-shaped slope. Since the slope has a certain guiding property, it is easier to align the cover 1 when it is installed on the box body 101. The wedge-shaped slope will generate a certain squeezing effect, so that the pressure ring 401 and the sealing ring 402 can fit more tightly, thereby effectively preventing the leakage of lubricating oil or other media.

[0032] A specific application of this embodiment is as follows: the gear is placed into the housing 101 and installed in place. Then, the output shaft connected to the gear is passed through the shaft hole 102 opened in the side wall of the housing cover 1. During the process of the housing cover 1 and the housing 101 coming close together, the pressure ring 401 provided on the back of the housing cover 1 moves with the housing cover 1 to the inner wall of the sealing ring 402 provided inside the housing 101. A sealing ring 403 is provided between the pressure ring 401 and the sealing ring 402. The sealing ring 403 is made of rubber and can be deformed by the pressure ring 401 and the sealing ring 402 being squeezed against each other, thereby better fitting the gap between the two, thereby increasing the sealing effect between the housing cover 1 and the housing 101. The surface where the pressure ring 401 and the sealing ring 402 meet is a wedge-shaped slope. Since the slope has a certain guiding property, it is easier to align the housing cover 1 when it is installed on the housing 101. The wedge-shaped slope will generate a certain squeezing effect, so that the pressure ring 401 and the sealing ring 402 can fit more tightly, thereby effectively preventing the leakage of lubricating oil or other media.

[0033] When the cover 1 is attached to the opening of the housing 101, the handles 301 on both sides are rotated. As the handles 301 rotate, the lead screw 202 rotates. As the lead screw 202 rotates, it pushes the locking plate 204 towards the housing 101 through the limiting ring 203. When the locking plate 204 contacts the surface of the fixing buckle 205 connected to the side wall of the housing 101, since both contact surfaces are inclined, as the locking plate 204 continues to press and move towards the fixing buckle 205, the housing 101 will move towards the cover 1 through the fixing buckle 205, thereby locking the cover 1 and the housing 101. This fixing method replaces the traditional screw fixing, allowing for quick installation and removal of the cover 1 to inspect, repair, or replace parts inside the gearbox, thereby improving maintenance efficiency, reducing equipment downtime, and helping to ensure the continuity and stability of production.
