Abstract
The invention discloses an improved vertical type motor guide bearing guide sleeve fastening structure. The fastening structure comprises a guide bearing seat, wherein a guide sleeve is arranged inside the guide bearing seat and spot welded on the side face of the guide bearing seat, a guide pillar is arranged inside the guide sleeve, a lock nut used for locking the guide sleeve is arranged on the guide pillar, and a slotting set screw is arranged between the guide bearing seat and the guide sleeve. The fastening structure disclosed by the invention has a simple and reasonable structure, improves the quality and the service life of the product, and is applied to the field of motors.
Description
Technical field
The present invention relates to technical field of motors, refer more particularly to a kind of improved vertical machine guide bearing guide pin bushing fastening structure.
Background technique
The current most of vertical machine guide bearing guide pin bushing of bearing bush structure and guide shaft bearing of adopting adopts Spielpassung, guarantee the fixing of guide pin bushing at afterbody by full weld after packing into, guarantee like this motor transportation and in servicely can not cause because of the vibration of guide bearing and guide pillar that guide pin bushing becomes flexible.Different due to the difference of rotating speed and working time, when rotating speed is fast, during continuous service, can be because the high vibration of guide bearing and guide pillar causes that guide pin bushing and guide shaft bearing weld scolder crack, when serious, scolder can get loose, cause the motor guide pillar loosening, cause the damaged in collision of guide bearing.
Summary of the invention
The purpose of this invention is to provide a kind of simple and reasonablely, can improve the quality of products and the improved vertical machine guide bearing guide pin bushing fastening structure in working life
.
The present invention is achieved in that improved vertical machine guide bearing guide pin bushing fastening structure, comprise in guide shaft bearing, guide shaft bearing and be provided with guide pin bushing, guide pin bushing and guide shaft bearing side point weld together, be provided with guide pillar in guide pin bushing, be provided with the locking nut of locking guide pin bushing on guide pillar, it is characterized in that: between described guide shaft bearing and guide pin bushing, be provided with the fluting Cock screw.
The present invention is simple and reasonable, has improved quality of product and working life
.
The accompanying drawing explanation
Fig. 1 is scheme of installation of the present invention;
Fig. 2 is enlarged view of the present invention;
In figure 1, frame, 2, the guide shaft bearing, 3, rotor shaft, 4, guide bearing, 5, top cover, 6, locking nut, 7, the fluting Cock screw, 8, guide pin bushing, 9, guide pillar.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated:
With reference to accompanying drawing, improved vertical machine guide bearing guide pin bushing fastening structure, comprise in guide shaft bearing 2, guide shaft bearing 2 and be provided with guide pin bushing 8, guide pin bushing 8 welds together with guide shaft bearing 2 side point, be provided with guide pillar 9 in guide pin bushing 8, be provided with the locking nut 6 of locking guide pin bushing 8 on guide pillar 9, it is characterized in that: be provided with fluting Cock screw 7 between described guide shaft bearing 2 and guide pin bushing 8.During concrete enforcement, the guide pin bushing plug is installed to bearing support, after packing at afterbody spot welding 2 points, the tapped hole with a M6 of guide bearing base inner surface junction processing at guide pin bushing then, the fluting Cock screw by M6 is by guide pin bushing and the pinning of guide shaft bearing.Fast when motor speed, during long operational time, can not cause because of the vibration of guide bearing and guide pillar getting loose of guide pin bushing.
