Description
Technical Field
The utility model relates to a mechanical transmission technical field especially relates to a flexible connection device for coupling joint.
Background
The coupler is a mechanical part which is mainly used for connecting two rotating shafts in mechanical transmission so as to transmit torque or a rotating angle; and can also be used for equipment protection of safety devices.
The coupling consists of two halves which are respectively connected with the driving shaft and the driven shaft. The power machine is connected with the working machine by a coupler, which is the most common connecting part for mechanical product shafting transmission. The development of the coupler products at home and abroad in the later stage of the 20 th century is fast, and how to select the coupler meeting the machine requirements from various couplers with various varieties and different performances in the product design always is a puzzling problem for most designers. In the high-speed heavy-load power transmission, some couplings also have the functions of buffering and damping and improving the dynamic performance of a shaft system.
The shaft coupling mainly falls into two major categories, flexible and rigid. The flexible coupling refers to a coupling in which a part of the coupling is flexible and deformable, and when the two rotating shafts are connected, a certain amount of misalignment of the two rotating shafts is allowed to occur, namely the coupling is deformable under dynamic conditions. When the coupler is used, the requirement on centering precision can be reduced, the test is convenient, and a good damping function is realized under the condition that the rotating speed is unstable. However, it has a disadvantage that it is low in strength, short in life, small in bearing capacity, not high temperature and low temperature, and only suitable for low temperature occasions, because it is made of rubber, nylon, etc.
A resilient pin coupling is the most commonly used one of the flexible couplings. The coupling is characterized in that a plurality of pins made of nonmetal elastic materials are placed in flange holes of two half couplings, and torque is transmitted through the pins to realize the coupling of the two half couplings.
The elastic pin type coupler has simple structure, easy manufacture, convenient assembly, disassembly and replacement of the elastic element and no need of moving the two couplers. The axial, radial and angular axis offset compensation device has the advantages of good axial, radial and angular axis offset compensation performance, good vibration reduction performance, simple structure, stable and reliable work, no noise, no need of lubrication, convenient maintenance, simple assembly and disassembly, good manufacturability, low cost, capability of being derived into various structural situations, good universality, wide application range and convenient popularization.
Usually, the material of elastic element pin generally chooses the nylon stick for use, has two axis of micro-compensation skew ability, and the elastic component during operation receives the shearing, and the operational reliability is extremely poor, only is applicable to the medium speed transmission shafting that requires very low, and one of the most outstanding advantage of elastic pin formula shaft coupling is that only once centering installation need, when changing elastic element, need not remove half-coupling, and reducible supplementary man-hour improves production efficiency, is particularly useful for the axis centering installation difficulty, when requiring to reduce as far as possible supplementary, provides production efficiency.
However, the nylon pin has the significant disadvantages that the nylon pin is hard and brittle, is easy to break or fracture, seriously influences the normal operation of production, increases the maintenance workload, and is a headache for practitioners.
