Oldham coupling
Overview of Oldham Couplings:
The cross slider coupling is also called the slider coupling. It consists of two half couplings with grooves on the end faces and an intermediate disc with convex teeth on both sides, because the convex teeth can be in the groove Sliding, so it can compensate the relative displacement between the two axes during installation and operation.
Application of Cross Slide Coupling:
Cross slide couplings are widely used in general machinery, hydraulic machinery, engineering machinery, metallurgical machinery, mining machinery, chemical machinery and other occasions.
Design of Oldham Coupling:
In the structural design and series design of the Oldham coupling, the shaft hole range of the coupling of each specification is determined based on the size of the transmitted torque, the structure of the coupling and the strength of the hub (YamatoThe allowable speed range of the small shaft hole) and the long cross slider coupling of the shaft hole is determined by calculation according to the allowable linear speed and outer edge size of different materials of the coupling.
The performance of the Oldham coupling:
1. Oldham coupling with simple structure, high-torque rigidity, high-sensitivity coupling;
2. The middle of the main body is connected by a cross slide block, which is convenient for installation and maintenance-free;
3. Allow large radial and angular deviations; zero rotation clearance;
4. The cross slide coupling is made of aluminum alloy and stainless steel;
5. Cross slide coupling can resist oil pollution and electrical insulation;
6. Fixing method of positioning screw;
7. Allow large radial and axial deviations;
8. Absorb relatively high transmission torque;
9. Long life and performance;
10. Not suitable for high-speed transmission occasions.
Installation of Oldham Coupling:
The cross slide coupling is composed of two shaft sleeves and a central slide.The center slide is usually made of engineering plastics as a torque transmission element, and other materials such as metal materials can be selected under the circumstances.The central sliding block is connected with the shaft sleeves on both sides by 90° oppositely distributed clamping slots on both sides, so as to achieve the purpose of torque transmission.The center sliding block and the shaft sleeve are matched with a slight pressure, which enables the coupling to run with zero clearance during the operation of the equipment.As the use time increases, the slider may lose its recoilless function due to wear, but the center slider is not expensive and easy to replace, and it can still play its original performance after replacement.
