Abstract

The utility model relates to a flat grinder bistrique bearing, including installing respectively in emery wheel axle fore -and -after left side bearing and right bearing, install respectively in the left bearing housing of the left bearing outside and tip and left bearing cap, install respectively in the right bearing housing of the right bearing outside and tip and right bearing cap, sealed bistrique casing around the bearing housing outside about in, left bearing and right bearing are two sets of back -to -back mounted's mating entad thrust ball bearing, and the emery wheel is installed to the left end of emery wheel axle. The beneficial effects of the utility model are that: two the same back -to -back pattern of single -row angular contact bearing dresses are whole as the supporting together, can bear great radial, the axial connected load that radial load gives first place to. But bearing group pretension has better supporting rigidity and running accuracy during the installation, the bearing adopts the grease lubrication, and it is few to consume emollient, is convenient for seal easy to maintain.

Description

Surface grinding machine bistrique bearing
Technical field
The utility model relates to a kind of surface grinding machine bistrique bearing.
Background technology
Surface grinding machine with horizontal spindle and rectangular table, this type of the more outmoded lathe bought especially, adds T operation for corase grind many.Because depth of cut during corase grind work pieces process is larger, the bistrique part of this kind equipment is 3 (or 5) bearing arrangements, and after using a period of time, because adjustment screw loosens, bearing and shaft clearance strengthen, and need irregularly to carry out gap adjustment.Long-time use rear axle and bearing bush abrasion seriously, need scraping bearing and again change.This adjustment, scraping and replacing must be undertaken by special technical staff, and time-consuming, effort, adjustment difficulty is large.Not only increase machine upkeep cost, and have a strong impact on manufacturing schedule, become a major issue urgently to be resolved hurrily in production.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of surface grinding machine bistrique bearing.
The utility model solves the technical scheme that its technical problem adopts: a kind of surface grinding machine bistrique bearing, comprise be installed on left bearing before and after grinding wheel spindle and right bearing respectively, be installed on outside left bearing respectively and the left bearing cover of end and left bearing lid, be installed on outside right bearing respectively and end right bearing cover and right bearing lid, seal around the bistrique housing outside Y-axis bearing sleeve, left bearing and right bearing are the angular contact ball bearing of the pairing of the back-to-back installation of two covers, and the left end of grinding wheel spindle is provided with emery wheel.
Further, left bearing and right bearing are 7009DB pairing bearing.
The beneficial effects of the utility model are: two identical back-to-back patterns of single-row angular contact bearing are fitted together as supporting integral, and can bear radial load is main larger radial direction, axial connected load.During installation, bearing group can pretension, has good support stiffness and running accuracy; Bearing adopts grease lubrication, consumes lubricant few, is convenient to sealing, is easy to safeguard.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. left bearing lid, 2. left bearing cover, 3. bistrique housing, 5. left bearing, 6. grinding wheel spindle, 7. right bearing, 8. right bearing cover, 9. right bearing lid, 10. emery wheel.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of surface grinding machine bistrique bearing as shown in Figure 1, comprise be installed on left bearing 5 before and after grinding wheel spindle 6 and right bearing 7 respectively, be installed on outside left bearing 5 respectively and the left bearing cover 2 of end and left bearing lid 1, be installed on outside right bearing 7 respectively and end right bearing cover 8 and right bearing lid 9, seal around the bistrique housing 3 outside Y-axis bearing sleeve 2,8, left bearing 5 and right bearing 7 are the angular contact ball bearing of the pairing of the back-to-back installation of two covers, and the left end of grinding wheel spindle 6 is provided with emery wheel 10.
Left bearing 5 and right bearing 7 are 7009DB pairing bearing.Grinding spindle bearing changes into and adopts high-precision pairing angular contact ball bearing, respectively fill a set of before and after main shaft, back-to-back installation, bearing is contained in left and right bearing holder (housing, cover) respectively, left and right bearing holder (housing, cover) is installed in body shell, and bearing lubrication only need be coated with lubricating grease when assembling or overhaul.
The advantage of this structure: 1. itself structure and operation principle ensure that its friction of motion factor is lower, and friction is less, has good mechanical efficiency, can keep lower power consumption, and starting performance is good in plant equipment operation process.2. end-play is smaller, and centripetal angular contact bearing can eliminate play with pre-tension method, and running accuracy is high; Have good precision and rotating speed, in equipment runs the friction that is subject to little, wear and tear low, therefore service life is longer.3. structure is simpler, and bearing exists loosening and wearing and tearing hardly, and the replacement cycle is long, even if change also more convenient, makes lathe be easier to maintenance process simulation.4. two identical back-to-back patterns of single-row angular contact bearing are fitted together as supporting integral, and can bear radial load is main larger radial direction, axial connected load.During installation, bearing group can pretension, has good support stiffness and running accuracy.5. bearing adopts grease lubrication, consumes lubricant few, is convenient to sealing, is easy to safeguard.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
