DL polygonal rubber couplingDL Polygonal Rubber Coupling is made of rubber material, made into a 6-angle (or octagonal) shape with a circular cross-section...The clamping shell coupling cannot be processed due to the long shaft hole, so make a lifting ring in the middle of the axial position to prevent axial movement, and secondly for the accuracy of the shaft hole.In practical applications, rigid couplings are often used instead of elastic pin couplings to connect the mixing shaft and the output shaft of the reducer, and the supporting points such as bottom bearings or intermediate bearings are eliminated.This use simplifies the application conditions of the single fulcrum bracket, but it is only suitable for occasions where the stirring is not strong, the power is small, and the bearing load is small.At this time, the coupling should use GT type rigid coupling to facilitate the slight adjustment of the axial size. In principle, the JQ type clamp coupling cannot be used. If the clamp coupling is used, the bearing structure of the fulcrum should be used. To make changes, use tightly tapered spherical roller bearings, or remove the lifting ring in the clamp coupling, so that the axial position of the stirring shaft has room for proper adjustment.The shaft does not need to move axially when assembling and disassembling, so it is very convenient to assemble and disassemble. The shortcomings of the clamping shell coupling are the low precision of the axis of the two shafts, the complicated structure and shape, and the low precision of manufacturing and balance. It is only applicable At low speeds and stable loads, the linear velocity of the outer edge is usually not greater than 5m/s. When the linear velocity exceeds 5m/s, balance verification is required.
The clamp shell coupling uses two clamp shells split along the axial direction, which are clamped by bolts to realize the connection of the two shafts. The torque is transmitted by the friction between the two halves of the coupling surface, and the flat key is used as an auxiliary connection.
Jacketed couplings are widely used in rolling mills, rubber, plastics, paper making, lifting, transportation, locomotives, electric power and other mechanical equipment.
