Come very naturally in the assembly of the installation is also very simple. In the installation if the use of artificial pressure with not only the labor intensity is too large and the size of each other is not easy to ensure the shaft, bearing and shaft sleeve, so the design of a special press be imperative. Graduation project this time is a tube axial compressive loading machine. This paper introduces the theoretical calculation to design sleeve pressing machine structure, working principle and main parts of the strength check and the advantages of the sleeve, pressing machine is efficient, economical, and high safety, stable operation. The overall plan . the relative position of two axle sleeve on the plane, the motor reducer to provide power through belt drives the screw rod to rotate, and drives t
