Abstract
The invention 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, between described frame cover plate and bearing cover and eccentric shaft, card is embedded with spacer ring respectively, leaves space, described frame cover plate end face has the annular groove that cross section is circular arc between described frame cover plate and the adjacent face of bearing cover。The present invention is used in combination adjustment by three groups of adjusting bolts, bearing cover, frame cover plate, it is ensured that dynamic pallet end face and stander end are in the face of neat, and Workpiece Machining Accuracy requires to reduce, and improve production efficiency, axially adjustable convenience, and efficiency of assembling improves。
Description
Technical field:
The present invention relates to compressor apparatus field, particularly to a kind of bearing of compressor mechanism for axial adjusting。
Background technology:
Bearing of compressor group and each parts axial dimension in the course of processing have the appearance of tolerance range, in assembling process, dynamic pallet end face can not reach parallel matching requirements with frame end face, having the requirement of tolerance range can not meet batch production by strictly controlling bearing group and each parts axial dimension in the course of processing, the low efficiency of assembling of yield rate is low。Even if adopting eccentric shaft to add adjustment pad, the efficiency of assembling in assembling is low, and repeated disassembled and assembled will also result in bearing group oils and fats and pollutes。
Summary of the invention:
The invention provides a kind of bearing of compressor mechanism for axial adjusting, solve requirement on machining accuracy in prior art high, the problem that efficiency of assembling is low。
The technology solution of the present invention 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, between described frame cover plate and bearing cover and eccentric shaft, card is embedded with spacer ring respectively, 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 keep balance in frame, thus improving assembly precision。
Further, described adjustment cap outer end is nested with dust cap。Play effect that is dust-proof and that prevent bearing group oils and fats 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 the length L of the eccentric segment of close dynamic pallet end face less than on eccentric shaft, and the thickness of described frame cover plate is the length D of the eccentric segment of close frame end face less than 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, the space left between frame cover plate and bearing cover can be passed through, the elastic deformation amount having with the annular groove having on frame cover plate, carrying out axially adjustable, the requirement on machining accuracy for eccentric shaft and bearing group reduces。
The beneficial effects of the present invention is: arrange three groups of adjusting bolts, bearing cover, frame cover plate are used in combination, by dismantling adjustment cap, utilize the space left between frame cover plate and bearing cover and the elastic deformation amount that the annular groove having on frame cover plate has, and adjusting bolt and pad, carry out axially adjustable, ensureing 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 adjustable convenience, efficiency of assembling improves。

Detailed description of the invention:
In conjunction with 1 ~ 3 pair, accompanying drawing one bearing of compressor mechanism for axial adjusting of the present invention, it is described further。
A kind of bearing of compressor mechanism for axial adjusting of the present invention, it includes frame 1, dynamic pallet 2, eccentric shaft 3, bearing group 4, adjusting bolt 5, pad 7 and adjustment cap 6, dynamic pallet 2 is sleeved in frame 1 by three groups of eccentric shafts 3 and bearing group 4, eccentric shaft 3 is bolted in frame 1 by adjusting bolt 5 and pad 7, frame 1 is bolted and fixed with adjustment cap 6 with corresponding section, adjusting bolt 5 position by bolt, eccentric shaft 3 there is bearing cover 8 near the eccentric segment upper sleeve of dynamic pallet 2 end face, near the eccentric segment upper sleeve organic frame cover plate 9 of frame 1 end face on eccentric shaft 3, between frame cover plate 9 and bearing cover 8 and eccentric shaft 3, card is embedded with spacer ring 10 respectively, space is left between the adjacent face of frame cover plate 9 and bearing cover 8, frame cover plate 9 end face has the annular groove 11 that cross section is circular arc。
Three groups of eccentric shafts 3 and bearing group 4 are evenly arranged in frame 1。
Adjustment cap 6 outer end is nested with dust cap 12。
Bearing group 4 bearing all adopts angular contact ball bearing。
Bearing cover 8 is secured by bolts on dynamic pallet 2 inner face。
The thickness of bearing cover 8 is the length L of the eccentric segment of close dynamic pallet 2 end face less than on eccentric shaft 3, and the thickness of frame cover plate 9 is the length D of the eccentric segment of close frame 1 end face less than on eccentric shaft 3。
