The existing casing of the servo planetary reducer includes an outer casing composed of a box body and a cover body.The box and cover are generally connected by bolts and nuts.If there is a deviation in the position of the corresponding mounting holes on the box body and the cover body, it will be very troublesome to install; at the same time, the box body is also easy to shake relative to the cover plate, and there is a radial deviation, which affects the performance of the servo planetary reducer.In addition, a lot of noise will be generated during operation, causing serious noise pollution.The servo planetary reducer often needs to be refueled during use.However, there is no refueling device on the current servo planetary reducer, and refueling is particularly troublesome.
Aiming at the deficiencies of the above technologies, a servo planetary reducer housing with simple and compact structure, fast and convenient installation, and noise reduction function is provided, which can effectively overcome the serious noise pollution of the prior art and the inconvenience of refueling during operation.
A reducer shell with noise reduction function comprises a shell, the side of the shell is connected with a fuel tank, and a sleeve is arranged inside the fuel tank, the sleeve is fixed to the bottom of the fuel tank, and the top is fixed to the fuel tank.The sleeve is open, the sleeve has a through hole, and the sleeve has a vertical rod that matches the sleeve. The bottom of the vertical rod is fixed with a floating ball. The top of the vertical rod protrudes from the fuel tank and is fixed with the cross bar. A limiting plate is arranged on the opposite side, the oil inlet and outlet are arranged on the side of the fuel tank, the valve is arranged on the oil outlet, the noise reduction box is arranged on the surface of the shell, and the noise reduction plate is relatively arranged in the noise reduction box.Noise reduction blocks are arranged on the gaps of the noise reduction boards, noise reduction holes are arranged between the noise reduction blocks in the noise reduction boards, and a vacuum layer is arranged between the noise reduction boards.
Compared with the prior art, the present invention provides a servo planetary reducer casing with simple and compact structure, fast and convenient installation, and noise reduction function.By using the noise reduction block on the sound insulation board, the noise generated during the operation of the reducer is continuously reflected between the noise reduction block and the sound insulation board.The vacuum layer prevents the transmission of noise.The setting of the sound insulation hole can effectively reduce the noise intensity and reduce the noise pollution; the oil tank is used to store oil.When it is necessary to send oil to the reducer, the oil can be taken from the oil outlet, which is very convenient; under the action of the floating ball, the cross bar can display the height of the oil level in the oil tank.When the cross bar touches the limit plate, it means that the oil in the tank is used up.It is necessary to replenish the oil in the fuel tank from the oil inlet in time, so that the fuel tank has the function of displaying the oil level.
