Abstract
The utility model discloses a kind of bearing of compressor mechanism for axial adjusting, it includes frame, dynamic pallet, eccentric shaft, bearing group, adjusting bolt, pad and adjustment cap, described eccentric shaft there is bearing cover near the eccentric segment upper sleeve of dynamic pallet end face, near the eccentric segment upper sleeve organic frame cover plate of frame end face on described eccentric shaft, described frame cover plate and between bearing cover and eccentric shaft respectively inlay card have spacer ring, space is left between described frame cover plate and the adjacent face of bearing cover, described frame cover plate end face has the annular groove that cross section is circular arc.The utility model is regulated by three groups of adjusting bolts, bearing cover, frame cover plate conbined usage, and ensure that dynamic pallet end face and stander end are in the face of neat, Workpiece Machining Accuracy requires to reduce, and improves production efficiency, axially easy to adjust, and efficiency of assembling improves.
Description
technical field:
The utility model relates to compressor apparatus field, particularly a kind of bearing of compressor mechanism for axial adjusting.
background technology:
Bearing of compressor group and each parts axial dimension in process have the appearance of tolerance range, in assembling process, dynamic pallet end face can not reach parallel matching requirements with frame end face, by strictly controlling bearing group and each parts axial dimension in process has the requirement of tolerance range not meet batch production, the low efficiency of assembling of yield rate is low.Even if adopt eccentric shaft to add adjustment pad, the efficiency of assembling in assembling is low, and repeated disassembled and assembled also can cause bearing group grease contamination.
utility model content:
The utility model provides a kind of bearing of compressor mechanism for axial adjusting, solves requirement on machining accuracy in prior art high, the problem that efficiency of assembling is low.
Technology solution of the present utility model is as follows: a kind of bearing of compressor mechanism for axial adjusting, it includes frame, dynamic pallet, eccentric shaft, bearing group, adjusting bolt, pad and adjustment cap, described dynamic pallet is sleeved in frame by three groups of eccentric shafts and bearing group, described eccentric shaft is bolted in frame by adjusting bolt and pad, described frame is bolted and fixed with adjustment cap with corresponding section, adjusting bolt position by bolt, described eccentric shaft there is bearing cover near the eccentric segment upper sleeve of dynamic pallet end face, near the eccentric segment upper sleeve organic frame cover plate of frame end face on described eccentric shaft, described frame cover plate and between bearing cover and eccentric shaft respectively inlay card have spacer ring, space is left between described frame cover plate and the adjacent face of bearing cover, described frame cover plate end face has the annular groove that cross section is circular arc.
Further, described three groups of eccentric shafts and bearing group are evenly arranged in frame.Three groups of eccentric shafts and bearing group are evenly arranged and make pallet in frame, keep balance, thus improve assembly precision.
Further, described adjustment cap outer end is nested with dust cap.Play a part dust-proof and prevent bearing group grease from leaking, convenient disassembly.
Further, described bearing group bearing all adopts angular contact ball bearing.
Further, described bearing cover is secured by bolts on dynamic pallet inner face.
Further, the thickness of described bearing cover is less than the length L near the eccentric segment of dynamic pallet end face on eccentric shaft, and the thickness of described frame cover plate is less than the length D near the eccentric segment of frame end face on eccentric shaft.Space is left between frame cover plate and the adjacent face of bearing cover, when dynamic pallet outer face exceeds frame outer face, by the space left between frame cover plate and bearing cover, with the elastic deformation amount that the annular groove that frame cover plate has has, carry out axial adjustment, the requirement on machining accuracy for eccentric shaft and bearing group reduces.
The beneficial effects of the utility model are: arrange three groups of adjusting bolts, bearing cover, frame cover plate conbined usage, by dismounting adjustment cap, utilize the space left between frame cover plate and bearing cover, and the elastic deformation amount that the annular groove that frame cover plate has has, and adjusting bolt and pad, carry out axial adjustment, ensure that dynamic pallet end face and stander end are in the face of neat, Workpiece Machining Accuracy requires to reduce, and improves production efficiency, axially easy to adjust, efficiency of assembling improves.
