Description

Technical Field

[0001] The utility model relates to the technical field of reducers for Raymond mills, and specifically relates to a transmission device for reducers for Raymond mills. Background Art

[0002] Raymond mill is widely used in the fine powder processing of more than 280 kinds of materials in non-flammable and explosive industries such as barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, thermal insulation materials, etc. with Mohs hardness not more than 9.3 and humidity below 6% in mining, chemical, construction and other industries. The finished particle size of R-type Raymond mill can be adjusted arbitrarily within the range of 80-325 mesh, and some materials can reach up to 600 mesh.

[0003] The reducer of a Raymond mill is an independent component consisting of a gear drive, a worm drive, or a gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0004] However, the existing reducer will generate heat and increase the temperature during operation. The lubricating oil on the reducer is easy to fail at high temperature, thereby reducing the service life of the reducer. The meshing and collision between the gears of the reducer during operation will also generate a lot of noise. Utility Model Content

[0007] Preferably, the screw and the protective cover are connected via a sealing bearing, the inner ring of the sealing bearing and the screw are interference fit, and the outer ring of the sealing bearing and the protective cover are fixedly connected.

[0008] Preferably, the air delivery pipe is a retractable hose.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can not only protect the reducer body through the setting of the protective cover to prevent the reducer body from being damaged by external collisions, but also reduce the noise generated by the reducer body during operation. The motor, screw, limit rod, hair dryer and fan arranged inside the protective cover can actively dissipate the heat of the reducer body to prevent the motor temperature of the reducer body from being too high and affecting its own service life.
