The elastic sleeve has a large structure, simple and reasonable, convenient maintenance, symmetrical and interchangeable on both sides, long life, allowing large axial movement, and has buffering, shock absorption, and other properties.The elastic sleeve is generally an elastic pin coupling, a nylon rod pin coupling, the former is connected by several screws, and the nut end of the screw is equipped with an elastic washer.The latter uses nylon rods. The two half-sections are drilled as large as holes, and the nylon rods are inserted. The outside is covered with a baffle, a pin coupling, and a pin coupling. The half couplings are connected by N nylon rods.Can play a role in compensation.
The material of the elastic sleeve is generally nylon 6, which has the ability to compensate for the deviation of the two axes in a small amount. The elastic part is sheared when working, and the workability is poor. It is only suitable for the medium-speed transmission shaft system with very low requirements, and is not suitable for high workability requirements. For example, the drive shaft system of the lifting mechanism of hoisting machinery cannot be selected, and it is not suitable for low-speed load-bearing, strong impact and large vibration transmission shaft system. For working conditions with large radial and angular deviations, and The transmission shaft system with lower installation accuracy should not be used as it is an obsolete type.The pin in the elastic pin coupling shaft is in shearing and squeezing state when working, and its strength condition is to calculate the shear strength of the cross section of the elastic pin and the squeezing strength of the pin and the pin hole wall.The elastic sleeve is a pin made of a number of non-metallic elastic materials, which is placed in the flange hole of the two halves of the coupling, and the two halves of the coupling are connected by the pin. The coupling has a simple structure, easy to manufacture, and assembly It is more convenient to change the elastic element, without moving the two couplings.
