Detailed Description
The principle of the utility model is that the ball bearing 3 is additionally arranged between the motor 4 and the belt pulley 6 to increase the supporting point, shorten the moment and reduce the axial force; furthermore, the ball bearing is fixed through the customized metal plate, the other end of the metal plate is fixed on a machine together with the motor through the same hole position, and additional holes are not needed.
The utility model discloses a: a support 1, a cover plate 2 and a ball bearing 3.
The present invention will be further explained with reference to the drawings and examples.
Example 1: as shown in fig. 2, 3, 4, 5 and 6, a shaft hole is opened in the middle of the support 1, a ball bearing 3 is embedded on the shaft hole edge, the ball bearing 3 is pressed on the shaft hole through a cover plate 2, and a supporting and fixing structure is protruded on the inner side edge of the support 1.
In the foregoing, the support 1 is sleeved on the driving shaft 10 of the motor 4 through the shaft hole, and meanwhile, the support 1 is fixed on the mounting structure of the motor 4 through the convex supporting and fixing structure.
In the foregoing, the edge of the cover plate 2 is fixed to the holder 1 by pressing the ball bearing 3 with a screw.
In the foregoing, the supporting and fixing structure protruding from the bottom of the support 1 is provided with the notch 9, and the opening width of the notch 9 is larger than the thickness of the tensioning elastic sheet 5.
In the foregoing, the support 1 is a slotted plate structure, and the bottom of the support 1 extends to two outer sides and is provided with fixing holes at the edges.
In the foregoing, the corner of the support 1 has two to four protruded support legs, and the support legs are provided with screw holes.
In the foregoing, the ball bearing 3 is pressed inside or outside the shaft hole by the cover plate 2.
The embodiment of the utility model provides an in, design sheet metal structure's support 1 increases the ball bearing 3 of establishing on drive shaft 10 with supporting the cover, utilizes the fixed sheet metal component of the installation hole site of current fixed runner motor 1, and 1 bottom one end of support is opened and is lacked groove 9 in order to avoid tensioning shell fragment 5 moreover.
