Description

Technical Field

[0001] The utility model relates to the field of helical gear reducers, in particular to a helical gear reducer with a protection function. Background Technique

[0002] The helical gear reducer is a novel speed reduction transmission device, adopting the most optimized and advanced design concept of the modular combination system, with the properties of small volume, light weight, large transmitted torque, smooth starting, and fine grading of transmission ratio. It can be arbitrarily connected and selected for a variety of installation positions according to user requirements.

[0003] In the prior art, when protecting the helical gear reducer, a protective shell is generally directly installed to avoid surface wear of the helical gear reducer. However, in a high-temperature working environment, heat will be generated when the helical gear reducer operates. If the heat cannot be dissipated, there is a risk of high-temperature explosion of the helical gear reducer, and dust is also likely to enter the helical gear reducer, resulting in damage to the internal accumulation of dust in the helical gear reducer. For this reason, we propose a helical gear reducer with a protection function to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a helical gear reducer with a protection function to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A helical gear reducer with a protection function includes a protection frame. The inner bottom wall of the protection frame is fixedly connected with a fixed frame. The upper surface of the fixed frame is installed with a reducer body through bolts. The front surface of the protection frame is fixedly connected with a fixed sleeve. A bearing is fixedly embedded in the inner wall of the fixed sleeve. Air inlet frames are fixedly communicated with both the left and right sides of the protection frame. Filter plates are placed on one side surface of the two air inlet frames close to each other. First mounting frames are fixedly connected to the inner walls of the two air inlet frames. Two first driving motors are fixedly connected to the outer surfaces of the two first mounting frames. An air inlet fan is fixedly connected to the output end of each first driving motor. An exhaust air frame is fixedly communicated with the back surface of the protection frame. A second mounting frame is fixedly connected to the inner wall of the exhaust air frame. A second driving motor is fixedly connected to the outer surface of the second mounting frame. A heat dissipation fan is fixedly connected to the output end of the second driving motor.

[0007] In a further embodiment, a plurality of sliding grooves are opened on the inner walls of the two air inlet frames. Two sliding blocks are fixedly connected to the outer surfaces of the two filter plates. Each sliding groove is adapted to the sliding block.

[0008] In a further embodiment, a protective cover is mounted on the upper surface of the protective frame by bolts, and handles are fixedly connected to the upper surfaces of the protective cover and the two filter plates.

[0009] In a further embodiment, a connecting plate is fixedly connected to the front surface of the fixed sleeve, and a plurality of connecting holes are formed in the front surface of the connecting plate.

[0010] In a further embodiment, protective nets are fixedly connected to the outer surfaces of the two air inlet frames and the outer surface of the air outlet frame, and a control panel is fixedly connected to the left side surface of the protective frame.

[0011] In a further embodiment, two mounting legs are fixedly connected to the bottom surface of the protective frame, and a plurality of mounting holes are formed in the bottom surfaces of the two mounting legs.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] A helical gear reducer with a protection function of the present utility model can effectively protect the helical gear reducer by installing the helical gear reducer in the protective frame to prevent it from being rubbed by the outside world. And during the use process, through the air inlet frame and the air outlet frame formed on the outer surface of the protective frame, with the cooperation of the driving motor, the inlet fan and the heat dissipation fan, the heat in the protective frame can be quickly discharged. And by installing filter plates inside the two air inlet frames, the dust in the air can be effectively filtered, thereby preventing the dust from entering the device. Therefore, the problem that the heat of the existing device cannot be discharged due to the protective cover during operation is solved by this device. BRIEF DESCRIPTION OF THE DRAWINGS
