The method and the specific steps of the belt wheel for ordinary lathe
First, looking is what type, it is type O or type A, type B and C, belt trough degree is 38 and 36 degrees, mill cutter, width, depth, and A few channel slot car according to the model. The section size of A type A triangle is: the top width is 13mm, the thickness is 8mm. The section size of type B triangle is: the top width Degree 17MM, the thickness is 10.5 MM. The section size of C type triangle is: the top width is 22MM, the thickness is 13.5 MM. The section size of the D type triangle is: the top width is 21.5 MM, the thickness is 19MM. The section size of E type triangle is: the top width 38MM, the thickness is 25.5 MM. Dimensions (width * height) : O (10 * 6), A (12.5 * 9), B (16.5 * 11), C (22 * 14), D (21.5 * 19), E (38 * 25.5)
Standard regulations of the state of v-belt type O, A, B, C, D, E, F seven kinds of models, there are three kinds of corresponding pulley wheel groove Angle 34 °, 36 °, 38 °, at the same time, rules for each triangle model corresponding to each small minimum diameter of pulley groove Angle, large pulley provisions have been made. The grooves of the pulley are divided into 32 degrees 34 degrees 36 degrees 38 degrees.
You can cut the bottom of the trough by cutting the slot knife (the width is smaller than the bottom), and then remove the excess metal with a sample knife by calculating the steps on both sides.
