Abstract
The invention relates to a coupling for a motor, which is composed of a bearing cover, a bearing, an oil blocking ring, a shaft sleeve, an upper bearing support, a check ring, a crossed shock absorbing sleeve, a shaft-coupling component, a shock absorbing component and a lower bearing support. The lower bearing support is connected with a connecting plate, the shaft-coupling component is connected with a lower shaft, the shock absorbing component is arranged on the outer side of the shaft-coupling component, and the crossed shock absorbing sleeve is sleeved on the upper portion of the shaft-coupling component and connected with an upper shaft. The check ring, the shaft sleeve, the oil blocking ring and the bearing are arranged in the upper bearing support and sequentially sleeved on the outer side of the upper shaft from bottom to top, and the bearing is embedded in the bearing cover. Compared with the prior art, the coupling for the motor is high in load-bearing strength, and the upper shaft and the lower shaft are not concentric so that the shafts are driven to perform centrifugation in a linkage mode.
Description
Technical field
The present invention relates to a kind of shaft coupling parts, especially relate to a kind of coupling for electric motor.
Background technique
The motor of centrifuge of the prior art all is that electric machine main shaft directly drives the centrifuge rotor rotation; Be not to be connected with the stainless steel main shaft of top through the motor of coupling with the below; Thereby below motor and top rotating shaft are turned round under the situation of decentraction; Therefore also do not have buffer system in addition, be not suitable for jumbo level and from the heavier angie type rotor of weight, using scope is limited.
Summary of the invention
The object of the invention is exactly to provide a kind of bearing capacity to increase, go up the lower shaft decentraction for the defective that overcomes above-mentioned existing technology existence to carry out the centrifugal coupling for electric motor of linkage moving axis.
The object of the invention can be realized through following technological scheme:
A kind of coupling for electric motor, this coupling are set in the axle and the outside of lower shaft, are fixed on through connecting plate on the big set square triangle of machine; It is characterized in that; Coupling is made up of bearing cap, bearing, oil deflector, axle sleeve, upper bearing bracket, back-up ring, cross shock absorbing sleeve, shaft coupling parts, vibration damper and step, and described step is connected with connecting plate, and described shaft coupling parts are connected with lower shaft; Described vibration damper is located at the outside of shaft coupling parts; Described cross shock absorbing sleeve is located at the shaft coupling upper parts of components, and this cross shock absorbing sleeve is connected with last axle, and described back-up ring, axle sleeve, oil deflector and bearing are located in the upper bearing bracket; Be set in the outside of axle from bottom to top successively, bearing is embedded in bearing cap.
The upper end of described lower shaft is connected with the shaft coupling parts through the internal screw thread line.
Described lower end of going up axle is milled with spline and is connected with the cross shock absorbing sleeve.
Compared with prior art; The present invention is connected with the stainless steel main shaft of top through the motor of shaft coupling parts with the below; The stainless steel main shaft of top directly connects centrifuge rotor, carries out centrifugation, and below motor and top rotating shaft are turned round under the situation of decentraction; Middle cross shock absorbing sleeve has played the effect of good buffering, is applicable to jumbo level and from the heavier angie type rotor of weight.
