In the figure: 1-1 parts of wheel body, 1-2 parts of end part, 1-3 parts of transmission gear, 1-4 parts of groove, 1-5 parts of circular clamping piece, 1-6 parts of chamfer, 1-7 parts of outer edge, 1-8 parts of chamfer area, 1-9 parts of boss, 1-10 parts of installation through hole, 1-11 parts of transmission shaft hole, 1 part of main belt pulley, 2 parts of secondary belt pulley, 3 parts of belt, 4 parts of main transmission shaft, 5 parts of motor, 6 parts of secondary transmission shaft, 7 parts of main body rotating animal.
Detailed Description
As shown in fig. 1 and 2, a novel belt pulley comprises a pulley body 1-1, bosses 1-9 and circular clamping pieces 1-5 which are integrally formed with the pulley body 1-1, wherein transmission teeth 1-3 for a belt are uniformly distributed on the end portion 1-2 of the pulley body 1-1, a groove 1-4 is formed between every two adjacent transmission teeth 1-3, and every two adjacent grooves 1-4 are parallel grooves; the grooves 1-4 are matched with the transmission teeth 1-3, so that the belt is more stable in transmission and better in traction force.
The two sides of the wheel body 1-1 are respectively provided with a round clamping piece 1-5, so that the belt can be prevented from sliding off.
The surface of the round card 1-5 back to the wheel body 1-1 is a plane.
One surface of the round card 1-5 facing the wheel body 1-1 is provided with a chamfer 1-6, and the chamfer 1-6 is arranged at a position close to the outer edge 1-7 of the wheel body 1-1; the chamfer angle 1-6 is an arc chamfer angle with the radius of 0.2 mm; the initial point of the chamfer 1-6 forms a radius with respect to the center of the circular card 1-5 equal to the radius of the wheel body 1-1.
The center of the circular card 1-5 is provided with a mounting through hole 1-10, and the circular card 1-5 is fixed on the boss 1-9 through the mounting through hole 1-10.
The round card 1-5 is jointed with the wheel body 1-1.
The center of the wheel body is provided with transmission shaft holes 1-11.
The outer ring formed by the edge of the circular card 1-5 and the chamfer 1-6 is the chamfer area 1-8, and the chamfer area 1-8 is an annular plane slightly inclined to the lower part at the moment, so that the contact surface of the belt and the chamfer area 1-8 is reduced in the rotating process, the friction force between the belt and the circular card 1-5 is reduced, the friction force between the belt and the edge of the belt pulley is reduced finally, and the problems of belt clamping and fur scraping belt pulleys are solved.
