Abstract
An adjustable rigid coupling for a large vertical circulating pump comprises an attachment bolt, a flange shaft sleeve and a coupling sleeve. A spindle end of a motor is rigidly connected with one end of the flange shaft sleeve through the attachment bolt, and an outer ring of the other end of the flange shaft sleeve is in trapezoid threaded coupling with an inner ring of the coupling sleeve; a pump spindle penetrates through the coupling sleeve and the flange shaft sleeve and is coupled with the flange shaft sleeve through a key, and a snap ring is coupled with the coupling sleeve; and the snap ring is arranged into a semi-open type and is arranged in a groove which is formed between the coupling sleeve and the pump spindle. The adjustable rigid coupling is simple in structure and separately transfers axial load and torque load, so that the safety reliability is high, the threads bearing the axial load adopt trapezoid threads, the axial bearing capacity is high, the structure reliability is improved, and the rotation axial clearance of a pump can be adjusted. The pump shaft is coupled with the coupling sleeve through the snap ring, when heavy load is generated during the equipment operation, the snap ring is used as a buffer unit to bear the breaking load, and other devices on a coupling structure can be protected.
Description
Technical field: the present invention relates to a kind of large-scale vertical recycle pump adjustable rigid coupling.
Background technique: the medium-and-large-sized verticle circulatory pump of the industry mainly adopts the coupler structure of rigidity at present, under installation, adjustment and repair, the operation of traditional rigid coupling structure when adjusting the rotor axial position is very inconvenient, bear simultaneously moment of torsion and thrust load, it is very high that structural strength requires, so this structure is in long-term using process, and the modulability of structure and reliability are all relatively poor, increase the cost of equipment, reduced working life.
Summary of the invention: purpose of the present invention will provide a kind of large-scale vertical recycle pump adjustable rigid coupling exactly, and it can solve existing large-scale vertical recycle pump and adopt the existing above problem of rigid coupling structure.The object of the present invention is achieved like this, a kind of large-scale vertical recycle pump adjustable rigid coupling, comprise attachment bolt, flange shaft sleeve, joint sleeve, it is characterized in that: an end of electric machine main shaft end and flange shaft sleeve is rigidly connected by attachment bolt, adopts trapezoidal thread to connect between the other end outer ring of flange shaft sleeve and the inner ring of joint sleeve; Pump shaft passes joint sleeve, flange shaft sleeve, and is connected with flange shaft sleeve by key, and snap ring connects with joint sleeve; Described snap ring is set to semi-open type, is arranged in the groove that arranges between joint sleeve and the pump shaft.The present invention is simple in structure, has realized the separate transmission of thrust load with torque load, has improved reliability of structure.The screw thread place of bearing thrust load adopts trapezoidal thread, and not only axial carrying capacity is strong, and safety reliability is high, and can adjust the axial clearance that pump turns by trapezoidal thread.Connect by snap ring between pump shaft and the joint sleeve, snap ring adopts the semi-open type structure, and when strong load appearred in the equipment operation, this snap ring bore breaking load as buffer unit, and can protect other devices on the coupler structure, and load distributes rationally, is easy to adjust.
Description of drawings:
Fig. 1 is structural representation of the present invention;
1. electric machine main shaft end, 2. attachment bolt, 3. flange shaft sleeve, 4. key, 5. joint sleeve, 6. snap ring, 7. pump shaft.
Embodiment: the invention will be further described below in conjunction with accompanying drawing;
A kind of large-scale vertical recycle pump adjustable rigid coupling, comprise attachment bolt 2, flange shaft sleeve 3, joint sleeve 5, it is characterized in that: electric machine main shaft end 1 is rigidly connected by attachment bolt 2 with an end of flange shaft sleeve 3, and the employing trapezoidal thread connects between the other end outer ring of flange shaft sleeve 3 and the inner ring of joint sleeve 5; Pump shaft 7 passes joint sleeve 5, flange shaft sleeve 3, and is connected with flange shaft sleeve 3 by key 4, and snap ring 6 connects with joint sleeve 5; Described snap ring 6 is set to semi-open type, is arranged in the groove that arranges between joint sleeve 5 and the pump shaft 7.During implementation, as shown in Figure 1, overall structure of the present invention is vertical installation, and electric machine main shaft end 1 is rigidly connected by attachment bolt 2 with an end of flange shaft sleeve 3, and the employing trapezoidal thread connects between the other end outer ring of flange shaft sleeve 3 and the inner ring of joint sleeve 5; Pump shaft 7 passes joint sleeve 5, flange shaft sleeve 3, and is connected with flange shaft sleeve 3 by key 4, and snap ring 6 connects with joint sleeve 5; Described snap ring 6 is set to semi-open type, to be easily installed in the groove that arranges on joint sleeve 5 and the pump shaft 7.The present invention all is delivered on the electric machine main shaft end 1 on top the thrust load on pump shaft 7 rotor parts such as grade by snap ring 6, joint sleeve 5 and flange shaft sleeve 3, pass through simultaneously key 4 transmitting torques between flange shaft sleeve 3 and the pump shaft 7, the upper-end surface of pump shaft 7 is left larger adjusting play in the axial direction, axially adjusts with convenient.Realize the separate transmission of thrust load with torque load, improved reliability of structure.The screw thread place of bearing thrust load adopts trapezoidal thread, and the axial carrying capacity of this worm structure is strong, and safety reliability is high, and can adjust the axial clearance that pump turns by trapezoidal thread.Connect by snap ring 6 between pump shaft 7 and the joint sleeve 5, snap ring adopts the semi-open type structure, and when strong load appearred in the equipment operation, this snap ring bore breaking load as buffer unit, can protect other devices on the coupler structure simultaneously.
