Detailed Description
Specific embodiments are given below in conjunction with fig. 1 and 2.
The utility model discloses an embodiment is to get the main shaft that driving motor drive diameter is phi 17mm and is the rotary motion that the rotational speed is 1000r/min, drives and carries out the linear velocity that a set of external diameter of location installation on main shaft is phi 42mm for phi 42 mm's round roller brush by the screw and erase the operation with 4.4m/s, and the dust cover is fixed and is prevented dust and convey the channel-section steel track of lower part on the main shaft. The auxiliary motor reducer drives a friction wheel with the diameter phi of 67mm to drive a pair of wheels with the diameter phi of 30mm to move on a No. 5 channel steel rail at the speed of 0.5m/s along the horizontal direction. The main shaft is connected with a main motor shaft through a sleeve, and a tapered roller bearing with the model number of 30203 is installed on the main shaft. The dust cover is installed on the main shaft through a pair of deep groove ball bearings with the model number of 7004AC and is fixedly connected with the cross beam through the double-side baffle plates. The main motor is connected and fixed with the cross beam through the motor base.
The same principle is adopted, the rotating speed of the motor is within the range of 750r/min-1000 r/min, the diameter of the group of round rollers is within the range of phi 40 mm-phi 52mm, and other embodiments of the utility model can be formed.
