Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a waterproof speed reducer. Background Technology

[0002] In modern industrial production, speed reducers are a key power transmission device widely used in various fields, from machining and automated production lines in manufacturing to wind power generation and water conservancy projects in the energy industry, and ship propulsion systems in the transportation sector. Speed ​​reducers play an indispensable role, undertaking the important task of reducing speed and increasing torque to meet the power output requirements of different working scenarios.

[0003] However, when the speed reducer is in a harsh environment such as humid, wet, or underwater, its waterproof performance faces a severe challenge. Taking outdoor machinery as an example, it is subjected to rain for a long time, and water can easily seep into the inside through the connection parts of the speed reducer housing. In industries such as aquaculture and sewage treatment, the speed reducer is in direct contact with water and faces a continuous risk of water ingress. Once water enters the inside of the speed reducer, it will cause a series of serious problems. Therefore, we propose a waterproof speed reducer. Utility Model Content

Detailed Implementation

[0018] 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 protection scope of the present utility model.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a waterproof speed reducer, including a protective shell 1, with fixed ring blocks 3 fixedly installed on both sides of the protective shell 1, a sealing gasket 4 sleeved on the outer surface of each fixed ring block 3, the sealing gasket 4 having a convex longitudinal section, a pressing member 5 on the outer surface of the sealing gasket 4, the pressing member 5 having a concave longitudinal section, a pressing ring plate 6 fixedly installed on the inner side of the pressing member 5, a sealing cap 2 fixedly installed on the side of each pressing ring plate 6, a fixing structure between the two sealing caps 2, a speed reducer assembly 10 inside the protective shell 1, the two ends of the speed reducer assembly 10 extending to the outside of the two sealing caps 2 respectively, and a port sealing assembly 9 on the side of each of the two sealing caps 2.

[0020] In an optional embodiment, two rubber pads 8 are provided between the protective shell 1 and the sealing gasket 4, with the two rubber pads 8 located on both sides of the fixing ring block 3 respectively.

[0021] It should be noted that the rubber gasket 8, through its own flexibility, improves the sealing effect and sealing performance of the sealing gasket 4, the clamping component 5, and the sealing cap 2 on the protective shell 1.

[0022] In an optional embodiment: two absorbent strips 7 are provided between the sealing gasket 4 and the clamping member 5, the two absorbent strips 7 are located on both sides of the clamping ring plate 6, and the absorbent strips 7 are made of highly absorbent resin composite material.

[0023] It should be noted that when a slight leak occurs in the sealed structure, the absorbent strip 7 quickly absorbs the moisture to prevent moisture from entering the internal core components.

[0024] In an optional embodiment: the fixing structure includes a plurality of screws 12, which are slidably mounted on the side ends of the two sealing caps 2. The plurality of screws 12 all pass through the side ends of the two sealing caps 2. Both ends of the screws 12 are threadedly connected to fixing nuts 14. A gasket 13 is provided between the fixing nuts 14 and the sealing caps 2.

[0025] It should be noted that after passing the screw 12 between the two sealing caps 2 and then putting the washer 13 on the screw 12, the fixing nuts 14 on both sides can be rotated to connect the sealing caps 2 on both sides with the protective shell 1.

[0026] In an optional embodiment: the port sealing assembly 9 includes a sealing cover 91, which is sleeved on the outer surface of the output end of the reducer assembly 10. The sealing cover 91 has two positioning grooves 92 inside, and each positioning groove 92 is provided with a positioning block 94. The side end of the positioning block 94 is provided with a fixing bolt 93, which is threadedly installed on the side end of the sealing cover 91. A sealing plate 95 is fixedly installed between the two positioning blocks 94. An extension ring 96 is fixedly installed on the inner side end of the sealing plate 95. The sealing cover 91 is connected to the sealing cover 2 through the installation structure.

[0027] It should be noted that when the connecting block 2 97 is inserted into the positioning groove 92, a certain cavity is formed between the sealing plate 95 and the sealing cover 91, which can store sealing oil. The sealing oil flows and is transferred between the cavity and the extension ring 96, which can provide lubrication for the output shaft.

[0028] In an optional embodiment: the mounting structure includes a connecting block 11, which is fixedly installed on the side of the sealing cover 2. Connecting blocks 2 97 are fixedly installed on the outer surfaces of both the connecting block 11 and the sealing cover 91. A through hole is provided on the side of the connecting block 2 97. The two connecting blocks 2 97 are connected by bolts and nuts.

[0029] It should be noted that by passing bolts and nuts through the through holes on the connecting block 2 97, the sealing cover 91 and the connecting block 1 11 can be connected together to protect the output end of the reducer assembly 10.

[0030] In practical use, the working principle of this utility model is as follows:

[0031] In use, the copper drum places the sealing gasket 4 on the outer surface of the fixing ring 3, forming the first sealing structure. Then, the clamping member 5 is placed on the outer surface of the sealing gasket 4, and the clamping ring plate 6 installed inside the clamping member 5 presses against the upper end of the sealing gasket 4, forming the second sealing structure. Simultaneously, both ends of the clamping ring plate 6 are equipped with absorbent strips 7, which quickly absorb moisture when a small amount of leakage occurs in the sealing structure, preventing moisture from entering the internal core components. The rubber gasket 8, through its own flexibility, improves the pressing effect and sealing performance of the sealing gasket 4, clamping member 5, and sealing cover 2 on the protective shell 1. Multiple seals can improve the waterproof effect of the reducer. Then, by passing the screw 12 between the two sealing covers 2, and then putting the gasket 13 on the screw 12, the fixing nuts 14 on both sides are rotated, thereby connecting the sealing covers 2 on both sides with the protective shell 1. By passing the bolt and nut through the through hole on the connecting block 2 97, the sealing cover 91 and the connecting block 1 11 can be connected together to protect the output end of the reducer assembly 10. By inserting the connecting block 2 97 into the positioning groove 92, a certain cavity is formed between the sealing plate 95 and the sealing cover 91, which can store sealing oil. The sealing oil flows and is transferred between the cavity and the extension ring 96, which can provide lubrication for the output shaft.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
