The toothed coupling is composed of internal gear ring with the same number of teeth and flange half coupling with outer teeth. The outer teeth are divided into two types: straight teeth and drum teeth. The so-called drum teeth are made into spherical surfaces, and the center of the spherical gear is on the axis of the gear. The side clearance of the gear is larger than that of the general gear. The drum gear coupling can allow larger angular displacement (relative to the straight tooth coupling), which can improve the contact conditions of the teeth, increase the ability of transmitting the torque, and prolong the service life. The contact state along the tooth width when angular displacement occurs.
When tooth couplings work, the two axes produce relative angular displacement. The internal and external teeth face periodically and axially slide relative to each other, which will inevitably form tooth wear and power consumption. Therefore, the gear coupling must work well and sealed. The toothed coupling has small radial size and large load capacity. It is usually used for shafting transmission under low speed and heavy load conditions. The high precision and dynamic balancing gear coupling can be used for high-speed transmission, such as the shaft transmission of a gas turbine. Drum gear couplings are widely used in drum gear couplings at the same time, because the angular compensation of drum gear couplings is greater than that of straight teeth couplings. The straight toothed coupling is a product that is eliminated.
The elastic column pin coupling has been listed as the national standard GB5014-85, and is suitable for all kinds of mechanical transmission shaft with two coaxial lines. The working temperature is -20 ~ +80 C, and the transfer nominal torque is 40 ~ 20000N.m.
The elastic column pin coupling has the advantages of simple structure, reasonable structure, convenient maintenance, double symmetry and interchangeability, long service life, large axial movement, and has the functions of cushioning, shock absorption and abrasion resistance.
Axial hole type is cylindrical (Y), conical (Z) and short cylindrical (J). The shaft hole and keyway are machined according to the national standard GB3852-83, shaft and keyway form and size. The semi coupling is made of precision casting, cast iron HT20-40, cast steel ZG35 II, shaft hole and keyway are drawn, and the pin is made of MC nylon B.
The elastic column pin coupling is a pin pin made of some non-metallic elastic materials, and is placed on the flange of the two shaft coupling. Kong Zhong realizes the connection between two halves by the pin pin. The coupling is simple in structure and easy to manufacture. It is more convenient to assemble and disassemble and replace elastic elements, and does not need to move the two half coupling. The elastic element (column pin) material is generally nylon, which has micro compensation for the two axis offset capability. The elastic parts are sheared at work, and the working reliability is very poor. It is only suitable for low speed medium speed drive shafts, and is not suitable for working conditions with high reliability.
The elastic sleeve pin coupling is installed in the flange hole of two shaft coupling by using a pin pin with elastic sleeve (rubber material) at one end to realize the connection of two half coupling. The elastic sleeve pin coupling used to be the most widely used coupling in our country. As early as the late 1950s, it has been formulated as the standard of mechanical part, JB08 - 60 elastic column pin coupling, and it is the first standard coupling in China.
The elastic sleeve pin coupling structure is relatively simple, easy to manufacture, no lubrication, no need to be bonded with metal, easy to replace elastic sleeve, no need to move half coupling, it has certain compensation for two axis relative offset and damping and cushioning performance. The work of elastic sleeve is subjected to compression deformation. Because the thickness of the elastic sleeve is thin, the volume is small, and the elastic deformation is limited, the elastic sleeve pin coupling can compensate for the displacement and elasticity of the axis, but the axial displacement allowance is less and the elasticity is weaker. The elastic sleeve pin coupling is generated by the locking force of the pin pin group and is generated by the friction torque on the contact surface, and the rubber elastic sleeve is compressed to transmit the torque. It is suitable for transmission of medium and small power shafts with good rigidity, high precision, little impact load and low vibration damping requirements.
1. the plum blossom elastic couplings are mainly meshed by two convex teeth and are subjected to radial extrusion to transmit torque. When the two axis has relative offset, the elastic elements have corresponding elastic deformation and play an automatic compensation role.
The 2. plum blossom elastic couplings are mainly used for starting frequent, positive reversals, medium high speed, medium torque and high reliability requirements, such as metallurgy, mining, petroleum, chemical engineering, lifting, transportation, light industry, textile, water pumps, fans, etc. The working environment temperature is from -35 to +80 C, the nominal torque is 25 to 12500Nm, and the allowable speed is 1500 to 15300r/min. 3. compared with other couplings, the plum blossom elastic couplings have the following characteristics:
(1) the work is stable and reliable, and has good damping, cushioning and electrical insulation properties.
(2) simple structure, small radial size, light weight and low rotational inertia. It is suitable for medium and high speed applications.
(3) it has large axial, radial and angular compensation capability.
(4) high strength polyurethane elastomer has good wear resistance and oil resistance, high carrying capacity, long service life, safety and reliability.
