Abstract
The utility model belongs to the technical field of mechanical engineering and mainly relates to a high-speed shaft coupling with polyurethane dowel pins. The shaft coupling mainly comprises two half couplings (2 and 5), wherein the half coupling (2) is connected with a main shaft, and the half coupling (5) is connected with a main motor; twelve dowel pin holes (7) are uniformly distributed in the corresponding positions on the circumferences of the half couplings (2 and 5); the half coupling (2 and 5) are connected with each other through the dowel pins (3) penetrating in the dowel pin holes (7); and strengthening ribs (4) are arranged respectively in the dowel pins (3) made of polyurethane material. By adopting the dowel pins made of polyurethane material as elastic coupling pieces, the utility model has the characteristics of high rotational speed, simple structure, portability and low cost.
Description
Technical field
The utility model belongs to mechanical engineering technical field, relates generally to a kind of polyurethane pin high speed coupling.
Background technique
The high speed coupling is as the term suggests be exactly that machine tool chief axis runs up, and the part that is used to connect between main motor and the main shaft is applied in the high-speed bearing testing machine; The high-speed bearing testing machine is by industrial control computer monitoring and control, and simulation test bearing actual load spectrum and rotating speed are composed operating mode, and the various performances of bearing are carried out certification test.In design process, because structure needs, select for use rotating speed can reach 26000 rev/mins coupling, present domestic high speed coupling all is to adopt external import known to the process investigation, each price that rotating speed is 20000 rev/mins is not less than 1500 yuan, and Heavy Weight, the cost height, performance parameter can not satisfy our requirement, the high-speed bearing testing machine is for satisfying the bearing performance test in addition, high-speed main spindle must have higher rotating accuracy, and the circular runout that requires main shaft usually is less than 1 or 2 μ m, and axial float is less than 1 μ m.In addition, main shaft also will have enough quiet, dynamic stiffness, to bear certain load and to keep high rotating accuracy.Because the nonlinearity after main motor and main shaft are direct-connected can cause vibration, therefore select the connection material between the high speed coupling extremely important equally.
Summary of the invention
The purpose of this utility model is to propose a kind of polyurethane pin high speed coupling, makes it have rotating speed height, simple for structure, light, characteristics that cost is low.
For finishing foregoing invention purpose the technical solution adopted in the utility model be:
A kind of polyurethane pin high speed coupling, described high speed coupling mainly comprises two half-couplings, and one of them half-coupling is connected with main shaft, and another half-coupling connects main motor; On the corresponding position of described two half-couplings, have 12 column pin holes that are uniformly distributed along the circumference respectively; Described two half-couplings connect by the pin that penetrates in the column pin hole, and stiffening rib is set respectively in the pin that polyurethane material is made.
A kind of polyurethane pin high speed coupling that the utility model proposes, two half-coupling attachment post pins adopt polyurethane material, adopt polyurethane to make elastomer and can in the hardness range of broad, have higher elasticity and intensity, excellent abrasive, oil resistance, fatigue resistance and anti-vibration resistance, under same rigidity, wider than other elastomer bearing capacity height, impact resistance height, resilience scope, be suitable for the high frequency deflection and use; , low noise light with other material weight/power ratio, wear-resistant, processing charges are low, corrosion-resistant, not embrittlement, have elastic memory, high-mechanic, can under 150 ℃ high temperature, work, have the title of " abrasive rubber "; Can utilize self good plasticity to compensate the relative skew of diaxon in the installation; Make the high speed coupling have rotating speed height, simple for structure, light, characteristics that cost is low.
