After establishing the roller assembly about the cylinder, the hollow end of the shaft strength conditions, should be combined with the heating medium under pressure cylinder, stress synthesis.
The strength conditions of the cylinder body and hollow end shaft in the drum assembly should be established after stress synthesis, combined with the pressure of the heating medium in the barrel.
The strength conditions of cylinder and hollow end shaft in the cylinder assembly shall be established after stress synthesis in combination with the pressure of the heating medium in the cylinder.<br>
