Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, the embodiment of the utility model provides a pair of sprocket feed for grinding machine, including speed reducer 1, motor 2, speed reducer sprocket 3, main shaft sprocket 4, chain 5, support 6, reducer shaft 7 and main shaft 8, motor 2 is connected with speed reducer 1, there is reducer shaft 7 on the 1 upside of speed reducer, reducer shaft 7 passes through key fixed connection with speed reducer sprocket 3, main shaft sprocket 4 passes through chain 5 with speed reducer sprocket 3 and is connected, main shaft 8 passes through key fixed connection with main shaft sprocket 4, 1 fixed mounting of speed reducer is in support 6 top.

Referring to fig. 1-2, reducer 1 is driven with main shaft 8 by reducer sprocket 3, main shaft sprocket 4, and chain 5.

Adopt above-mentioned scheme: through setting up speed reducer 1 and main shaft 8's transmission mode into speed reducer sprocket 3, main shaft sprocket 4, 5 cooperations of chain use transmissions, reduced the radial runout in the processing and skid, increased life.

The utility model discloses a theory of operation:

when processing,

motor

2 and 1 fixed connection of speed reducer, speed reducer shaft 7 passes through key fixedly connected with speed reducer sprocket 3, and main shaft sprocket 4 passes through chain 5 and is connected with speed reducer sprocket 3, and main shaft 8 and 4 fixed connection of main shaft sprocket, motor work drive speed reducer sprocket 3 rotate to drive the motion of main shaft sprocket, and then drive the rotatory work of mill through the main shaft.

In summary, the following steps: the chain wheel transmission device solves the problems of radial run-out and slipping in processing by matching the speed reducer 1, the motor 2, the speed reducer chain wheel 3, the main shaft chain wheel 4, the chain 5, the support 6, the speed reducer shaft 7 and the main shaft 8.
