The sleeve coupling of the opposite wheel uses a common sleeve and uses rigid couplings such as keys, splines or taper pins to realize the connection of the two shafts. The sleeve coupling has simple structure, convenient manufacture, low cost, and small radial size, but it is inconvenient to assemble and disassemble, and the shaft needs to be moved axially. Short is suitable for low speed, light load, no impact load, work balance and connection of upper dimension shaft. The maximum working speed is generally not more than 250r/min. The sleeve coupling does not have axial, radial and angular compensation performance.
In the formula, Tc—calculated torque, Nmm; D—outer diameter of sleeve, mm; d—diameter of shaft, mm, when using spline connection, d takes the average diameter of spline; []——sleeve The allowable shear stress of the cylinder, N/mm2, for the No. 45 steel sleeve, []=35～40N/mm2 is desirable. Check the shear strength of the conical pin connection:
In the formula, d1——the diameter of the conical pin, mm; []——the allowable shear stress of the conical pin, N/mm2, []=0.25 is desirable, which means that the yield of the pin material is excellent.
