Abstract
The utility model discloses a kind of anchoring drilling machine guide roller, cap (2) is connected by screw the one end in roller bearing (3), the other end of roller bearing (3) is fastened on axle sleeve (5) by bearing (6) and nut (7), one end that axle sleeve (5) closes on cap (2) is provided with dust ring, the other end of axle sleeve (5) is provided with stifle (8), sealing ring and hole back-up ring (10), also comprises one is carried out injecting grease for lubricating grease nipple (11) to bearing (6).The utility model has rational in infrastructure, simple, easy to use, connects reliable, changes the features such as convenient.Seal lubrication designs, and can keep the advantage of smart scroll at operating environment under being full of the condition of earth, dust.Adjustable cap, roller size, can meet different guide clearance sizes, have very strong versatility.Only need in case of wear to change cap or roller bearing, economical and practical.Can be used as operating environment difference, axial-radial stressed little when use.
Description
Technical field
The utility model relates to a kind of guide roller, particularly relates to a kind of anchoring drilling machine guide roller.
Background technology
The unit head guiding of tradition drilling tool machinery adopts wear resistant nylon slide block, in use because operating environment is severe, and foreign material such as guide pass accumulation dust, aggregate chips etc., can not root out in time, nylon slide block is in motion process, and self wearing and tearing is very fast, simultaneously very fast to way rub.Under serious wear condition, guide rail and unit head gap are comparatively large, and in work progress, loom rocks severity, and machine adds extra dynamic loading, the wearing and tearing of aggravation mechanical fatigue.When changing guide rail, needing whole unit head to take apart, removing and installing difficulty.How to solve the quick abrasion occurred in above-mentioned engineering, change difficulty, after wearing and tearing, machinery rocks greatly, the difficult problems such as impact shock is large, has carried out replaceable roller design as unit head walking guiding, has achieved good effect in actual use.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of connect reliable, change that convenience, seal lubrication, rotation are flexible, highly versatile, economical and practical anchoring drilling machine guide roller.
In order to solve the problems of the technologies described above, the anchoring drilling machine guide roller that the utility model provides, cap is connected by screw the one end at roller bearing, the other end of described roller bearing is fastened on axle sleeve by bearing and nut, described axle sleeve is fixedly connected on above other structures by bolt, one end that described axle sleeve closes on described cap is provided with framework dustproof loop, the other end of described axle sleeve is provided with stifle, sealing ring and hole back-up ring, also comprises one is carried out injecting grease for lubricating grease nipple to described bearing.
Particularly, described screw is soket head cap screw.
Preferably, described sealing ring is O shape circle.
Preferably, described bearing is two.
Grease nipple is located on described stifle particularly.
Adopt the anchoring drilling machine guide roller of technique scheme, axle sleeve two ends define the clean lubrication environment of a sealing to bearing by framework dustproof loop, stifle, sealing ring, hole back-up ring, carry out injecting grease for lubricating by grease nipple.There is dismountable cap as Rolling wear part, also can disassemble cap, directly use roller bearing as rolling element.By different roller bearings and the distance between cap size adjustment structure body and guide rail, the scope of application is wide.Roller bearing is fastened on axle sleeve by two bearings and nut, ensures the axial not play of roller bearing.Two ends define the clean lubrication environment of a sealing to bearing by framework dustproof loop, stifle, sealing ring, hole back-up ring.Stifle passing hole back-up ring blocks, and installation, dismounting and change conveniently, also can not be exited under vibration condition and get loose.
The utility model is, axial-radial stressed little feature large based on anchoring drilling machine operating environment bisque, dirt, and a kind of guide roller of R & D design, the rig head for other types leads, and has the very wide scope of application.Be full of the condition of earth, dust in particular to operating environment, for rolling guide frame body, this structure design can keep smart scroll, airtight lubrication and do not destroy spigot surface
Replaceable roller also can be used in all moving guiding mechanisms of rolling pair contact, and the lubrication environment particularly sealed, can be used for above the severe Foundation Design machinery of operating environment.
In sum, the utility model be a kind of rational in infrastructure, simple, easy to use, connect reliable, change that convenience, seal lubrication, rotation are flexible, highly versatile, economical and practical anchoring drilling machine guide roller.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is soket head cap screw, and 2 is cap, and 3 is roller bearing, and 4 is framework dustproof loop, and 5 is axle sleeve, and 6 is bearing, and 7 is nut, and 8 is stifle, and 9 is O shape circle, and 10 is hole back-up ring, and 11 is grease nipple.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, cap 2 is connected by screw the one end at roller bearing 3, the other end of roller bearing 3 is fastened on axle sleeve 5 by two bearings 6 and nut 7, axle sleeve 5 is fixedly connected on above other structures by bolt, one end that axle sleeve 5 closes on cap 2 is provided with framework dustproof loop 4, the other end of axle sleeve 5 is provided with stifle 8, sealing ring and hole back-up ring 10, and sealing ring is O shape circle 9, also comprises one is carried out injecting grease for lubricating grease nipple 11 to bearing 6.Particularly, grease nipple 11 is located on stifle 8.
Preferably, screw adopts soket head cap screw 1.
See Fig. 1, axle sleeve 5 two ends define the clean lubrication environment of a sealing to bearing 6 by framework dustproof loop 4, stifle 8, O shape circle 9 and hole back-up ring 10, carry out injecting grease for lubricating by grease nipple 11.
There is dismountable cap 2 as Rolling wear part, also can disassemble cap 2, directly use roller bearing 3 as rolling element.By different roller bearings 3 and the distance between cap 2 size adjustment structure body and guide rail.
Roller bearing 3 is fastened on axle sleeve 5 by two bearings 6 and nut 7, ensures the axial not play of roller bearing 3.
Stifle 8 passing hole back-up ring 10 blocks, and installation, dismounting and change are conveniently.
