The fixed base 2 has a ring of bolt holes. You can use bolts to fix the pulley 4 on the fixed base 2. Then slide the pins 5 at the top and bottom of the U-shaped measuring frame 3 to make them contact the pulley 4. Then read the scale indicated by the pointer 6. The outer diameter of the pulley 4 is the dimension mark value of the vertical side outer wall of the U-shaped measuring frame 3 minus the scale value read.

[0012] In a further implementation, refer to Figure 2 A toothed groove width measuring component is provided on the inner wall of the vertical side of the C-shaped measuring frame 3. The toothed groove width measuring component is located above the fixed base 2. The toothed groove width measuring component includes a sliding groove 8, a sliding column 9, a fixed cross bar 10, and a movable cross bar 11. Multiple sliding grooves 8 are provided. The sliding grooves 8 are horizontally and evenly spaced on the inner wall of the vertical side of the C-shaped measuring frame 3. One end of the sliding column 9 is inserted into one of the sliding grooves 8, and the other end of the sliding column 9 is away from the sliding groove 8. The fixed cross bar 10 and the movable cross bar 11 are both located at the lower end of the sliding column 9. The fixed cross bar 10 is fixedly connected to the sliding column 9, and the movable cross bar 11 is fixedly connected to the sliding column 9 and slidably connected.

[0013] In a further implementation, refer to Figure 2 A tooth groove angle measuring component is provided on the inner wall of the vertical side of the U-shaped measuring frame 3. The tooth groove angle measuring component is located below the fixed base 2. The tooth groove angle measuring component includes a sliding groove 8, a sliding column 9, a fixed triangle plate 12, and a movable triangle plate 13. There are multiple sliding grooves 8, which are horizontally and evenly spaced on the inner wall of the vertical side of the U-shaped measuring frame 3. One end of the sliding column 9 is inserted into one of the sliding grooves 8, and the other end of the sliding column 9 is away from the sliding groove 8. The fixed triangle plate 12 and the movable triangle plate 13 are both located on the upper end of the sliding column 9. The fixed triangle plate 12 is fixedly connected to the sliding column 9, and the movable triangle plate 13 is fixedly connected to the sliding column 9 and slidably connected. The sliding column 9 can slide in the sliding groove 8, and the fixed triangle plate 12 and the movable triangle plate 13 are inserted into the tooth groove of the pulley 4.

[0014] Specifically, the sliding column 9 is detachably installed in the sliding groove 8. There is only one sliding column 9. The appropriate sliding groove 8 is selected according to the size of the pulley 4. The fixed cross bar 10, movable cross bar 11, fixed triangle plate 12 and movable triangle plate 13 on the sliding column 9 are standard parts with the same tooth groove shape as the pulley 4 of each size. Sliding columns 9 of each specification are manufactured in advance. The diameter of the fixed cross bar 10 and the movable cross bar 11 is the same as the width at the pitch circle of the tooth groove of the pulley 4. The shape of the fixed triangle plate 12 and the movable triangle plate 13 is the same as the tooth groove shape of the pulley 4.

[0015] When using this utility model, first fix the bracket 1 vertically on any horizontal surface to ensure that the bracket 1 will not tilt. Then install the pulley 4 on the fixed base 2. The fixed base 2 has a ring of bolt holes. The pulley 4 can be fixed on the fixed base 2 with bolts. Then slide the pins 5 at the top and bottom of the C-shaped measuring frame 3 to make them contact the pulley 4. Then read the scale indicated by the pointer 6. The outer diameter of the pulley 4 is the dimension mark value of the vertical side outer wall of the C-shaped measuring frame 3 minus the read scale value. Then, insert the sliding pin 9 in the tooth groove width measuring assembly into the appropriate sliding groove 8 so that the sliding pin 9 can pass through the tooth groove at the top of the pulley 4 when it moves. Adjust the distance between the fixed cross bar 10 and the movable cross bar 11 according to the standard tooth groove of the pulley 4. The distance between the fixed cross bar 10 and the movable cross bar 11 is the width of the tooth groove at the pitch circle. Then push the sliding pin 9. If the sliding pin 9 can pass through the tooth groove at the top of the pulley 4 smoothly, the tooth groove width of the pulley 4 is qualified. If it is blocked and cannot pass through, the pulley 4 is unqualified and needs to be repaired or replaced. Then, the sliding pin 9 in the tooth groove angle measuring assembly is inserted into the appropriate sliding groove 8 so that the sliding pin 9 can pass through the tooth groove at the top of the pulley 4 when it moves. According to the distance between the fixed triangle plate 12 and the movable triangle plate 13 of the standard tooth groove of the pulley 4, the fixed triangle plate 12 and the movable triangle plate 13 are made to form a shape that can mesh with the adjacent tooth grooves and the tooth phases between the tooth grooves on the pulley 4. Then, the sliding pin 9 is pushed. If the sliding pin 9 can pass through the tooth groove at the top of the pulley 4 smoothly, the tooth groove angle of the pulley 4 is qualified. If it is blocked and cannot pass through, the pulley 4 is unqualified and needs to be repaired or replaced. This utility model is equipped with a pin, a tooth groove width measuring component, and a tooth groove angle measuring component, which can simultaneously measure the outer diameter, tooth groove width, and tooth groove angle of the pulley, helping after-sales maintenance personnel to quickly determine the damage of the pulley.
