[0002] Gear reducers are generally used for low-speed and high-torque transmission equipment. Ordinary reducers for electric motors will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of large and small gears is the transmission ratio. With the continuous development of the reducer industry, more and more companies are using gear reducers.

The utility model drives the screw rod to rotate in the threaded barrel on both sides of the shell by rotating the two swivels, and the screw rod will rotate in the bearings on both sides of the rubber plate. When the screw rod rotates, it can drive the support plate and the pressure head to contact the rubber plate, thereby fixing the rubber plate in the contact gap of the gear reducer.

[0027] A preferred embodiment of a light and thin gear reducer provided by the utility model is as follows Figures 1 to 5 As shown: a thin and light gear reducer, including a mounting base 1, the top of the mounting base 1 is fixedly connected to a reducer body 2, the side of the reducer body 2 is provided with a protective shell 3 that fits with the mounting base 1, the top of the mounting base 1 is fixedly connected to a sealing plate 4 that fits with the reducer body 2, heat dissipation holes 5 are provided on both sides of the protective shell 3, the sides of two groups of heat dissipation holes 5 are fixedly connected to shielding plates 6 that are fixedly connected to the protective shell 3, and one side of the two groups of shielding plates 6 is fitted with a dust filter plate 7.

[0028] In this embodiment, both sides of the sealing plate 4 are in close fit with the protective shell 3, and there is no gap between the sealing plate 4 and the reducer body 2 and the protective shell 3. By setting the sealing plate 4, the sealing plate 4 and the protective shell 3 are in close fit, so when the protective shell 3 covers the reducer body 2, it can cooperate with the sealing plate 4 to prevent the reducer body 2 from being exposed to the outside.

[0029] In this embodiment, the shielding plate 6 is tilted downward, and the shielding plate 6 tightly wraps around the heat dissipation hole 5. The shielding plate 6 is tilted, so as to prevent dust from entering the protective shell 3 through the heat dissipation hole 5.

[0030] In this embodiment, the dust filter plate 7 is magnetically connected to the baffle plate 6. The dust filter plate 7 is detachable. The dust filter plate 7 is magnetically connected to the baffle plate 6. Therefore, the dust filter plate 7 can be disassembled at any time to clean the dust on its surface to prevent dust from blocking the heat dissipation holes 5 from dissipating heat.

[0031] Example 2

[0032] Based on Example 1, a preferred embodiment of a thin and light gear reducer provided by the present invention is as follows: Figures 1 to 5 As shown: a control plate 8 is slidably connected inside the protective shell 3, connecting rods 9 are fixedly connected on both sides of the control plate 8, and the surfaces of the two groups of connecting rods 9 are slidably connected with limit plates 10 fixedly connected to the protective shell 3, and a nut 11 threadedly connected to the connecting rod 9 is provided on one side of the limit plate 10, and the tails of the two groups of control plates 8 are fixedly connected with mounting plates 12, and the tails of the two groups of mounting plates 12 are fixedly connected with dampers 13, and the tails of the two groups of dampers 13 are fixedly connected with rubber plates 14 that fit the reducer body 2, and the top of the mounting seat 1 is rotatably connected with forward and reverse screws 15, and the surfaces of the forward and reverse screws 15 are threadedly connected with two groups of plug plates 16 that are slidably connected to the mounting seat 1 and embedded in the protective shell 3.

[0033] In this embodiment, the control board 8 forms a fixed structure inside the limit plate 10 through the nut 11, and the position of the rubber plate 14 can be adjusted through the control board 8. It only needs to pull the control board 8 to slide inside the protective shell 3, and finally tighten the nut 11 to prevent the rubber plate 14 from moving.

[0034] In this embodiment, the damper 13 is arranged horizontally and equidistantly on one side of the mounting plate 12, and the damper 13 and the rubber plate 14 are perpendicular to each other. Through the rubber plate 14 and the damper 13, when the reducer body 2 is working, the amplitude of the left and right shaking of the reducer body 2 can be reduced, thereby improving the stability of the device.

[0035] In this embodiment, the plug plate 16 fits tightly against the inner wall of the protective shell 3, and the protective shell 3 forms a fixed structure through the plug plate 16. The forward and reverse screws 15 are rotated to control the two groups of plug plates 16 to slide away from each other along the top of the mounting base 1. When the two groups of plug plates 16 slide out of the interior of the protective shell 3, the protective shell 3 can be removed to inspect the reducer body 2.

[0036] The working principle and use process of the utility model are as follows: first, by setting a sealing plate 4, the sealing plate 4 is tightly fitted with the protective shell 3, so when the protective shell 3 covers the reducer body 2, it can cooperate with the sealing plate 4 to prevent the reducer body 2 from being exposed to the outside. When the equipment is working, the heat dissipated by the reducer body 2 can be dissipated through the heat dissipation holes 5, and the shielding plate 6 is inclined, so that dust can be prevented from entering the protective shell 3 from the heat dissipation holes 5. The dust filter plate 7 and the shielding plate 6 are magnetically connected, so the dust filter plate 7 can be disassembled at any time to clean the dust on its surface to prevent dust from blocking the heat dissipation of the heat dissipation holes 5.

[0037] By means of the rubber plate 14 and the damper 13, when the reducer body 2 is working, the amplitude of the left and right shaking of the reducer body 2 can be reduced, and the stability of the device can be improved. The position of the rubber plate 14 can be adjusted by the control panel 8. It is only necessary to pull the control panel 8 to slide inside the protective shell 3, and finally, the nut 11 can be turned to prevent the rubber plate 14 from moving. When it is necessary to quickly disassemble the shell to inspect the reducer body 3, the forward and reverse screws 15 are rotated to control the two sets of plug plates 16 to slide away from each other along the top of the mounting seat 1. When the two sets of plug plates 16 slide out of the protective shell 3, the protective shell 3 can be removed to inspect the reducer body 2.
