The different those widened sections of at least two radial direction radiuses are equipped with to through hole；The belt pulley also includes the positioning for being used to position belt
Block and clamping piece, the positioning block gap and are evenly mounted on the left and right cell wall of belt grooves, the left and right side of locating piece
The inner side of left and right cell wall is connected in respectively, and lug boss is equipped with the left and right side of locating piece, and the lug boss is arranged in
Guide through hole can simultaneously be slided in guide through hole；The clamping piece is inserted in the corresponding those widened sections of left and right cell wall respectively, and convex
It is resisted against on the inside of the portion of rising on clamping piece.
Further, the outer face of the locating piece is in circular arc.
Further, the guide through hole is rectangular, and four are equipped with the length direction of each guide through hole and is widened
Portion；The clamping piece is made up of Access Division and Handheld Division, and the width of Handheld Division is more than Access Division and externally protrudes out in left and right cell wall, institute
Access Division is stated to be connected in those widened sections.
Further, one layer of frosted layer is formed on the inwall of the belt grooves.Increase and the frictional force of belt side.
Further, the belt pulley also includes a bearing, and the bearing includes setting on inner ring, outer ring and ball, inner ring
There is interior raceway, outer ring is provided with outer raceway, and the radial section of the interior raceway and outer raceway is triangular in shape, the ball difference
It is tangent with inside and outside raceway.It is tangent between ball and inside and outside raceway so that contact area diminishes, reduce friction during rolling
Power, the not only more conducively rolling of ball, and the heat produced by friction is decreased, so as to lift service life.
From above-mentioned to description of the present utility model, compared to the prior art, the utility model has the following advantages that：It is logical
Locating piece, can be positioned on different radial direction radiuses by the those widened sections crossed in guide through hole and the cooperation of clamping piece, and belt
Locating piece lateral surface is socketed in, therefore, just can be realized to pulley outer diameter by the way that clamping piece is positioned in different those widened sections
Adjustment so that there are belt pulley of the present utility model a variety of external diameters to go to coordinate the belt of different length, and then expand
The application of belt pulley.
