Abstract
The invention discloses a self-lubricating grinding roll which comprises a gland nut, a cross-arm shaft seat, adjusting pads, a seal cartridge, an upper bearing gland, a grinding roll shaft, a roll covering lining, a grinding roll covering, an oil tank and an oil tank shield. The self-lubricating grinding roll is characterized in that the gland nut is arranged at one end of the grinding roll shaft and is connected with the cross-arm shaft seat, the bottom of the cross-arm shaft seat and the seal cartridge are mutually anchored through bolts, step surfaces of the cross-arm shaft seat and the grinding roll shaft are provided with the adjusting pads, one end of the upper bearing gland fits with the inner wall of the seal cartridge, the oil tank and a bearing pressing sleeve are mutually anchored through oil tank gland bolts, and an internal taper aperture of the grinding roll covering is smaller at top and larger at bottom and is fixed on the roll covering lining through the gland bolts. The self-lubricating grinding roll provided in the invention has the advantages of a simple structure, usage safety, a long service life and uniform wearing.
Description
Technical field
The invention belongs to the abrasive dust field of mechanical technique, specifically the self-lubricating grinding roller.
Background technology
The steel seal of the assembly of at present common Suspension roller grinding roller of wheat flour-milling on the grinding roller axle, is rotary body through bolt, forms labyrinth sealing with the bearing lower cover; All there is excesssive gap in labyrinth-type excluder when processing and assembling, dust is got in the bearing chamber, damages bearing; The steel seal can not accurately be located and caused and bearing lower cover frictional heat when the gap was too small, influenced equipment operation.The big up and small down shape of original grinding roller internal taper is fixed on the grinding roller axial cone degree position through extremity piece grinding roller clamp nut; Existing craft precision is difficult to reach requirement; In the grinding machine course of work, lower end grinding roller clamp nut is in the Frotteurism with material all the time, and it is loosening clamp nut to occur through regular meeting; Cause grinding roller fully not compress even to come off, make equipment not run well even security incident occurs; To add dress lubricating oil in order reducing to rub between the axle of rotation and the spare and accessory parts, to lubricate parts, but, can not make grinding roller realize whole lubricating, the uneven situation of parts wear occur because the drawback of original structure causes the lubricating oil flowability not strong.
Summary of the invention
The invention reside in and address the deficiencies of the prior art, provide a kind of simple in structure, safe in utilization, the life-span is long, wearing and tearing evenly, grinding roller that can self-lubricating.
Technical scheme of the present invention realizes in the following manner: the self-lubricating grinding roller comprises: clamp nut, cross-arm axle bed; The adjustment pad, sealing shroud, bearing upper press cover; The grinding roller axle; Roller leather sheet cover, grinding roller roller skin, (middle groove changes over yi word pattern, cross, impeller type, column type, pyramid type, gear type, fan type, umbellate form, dome-type, bowl type, square, diamond pattern, triangular form, ball-type, trumpet type etc. as required for oil sump and oil sump groove; If any this groove of specific (special) requirements also can, adopt plate armature.) the oil sump guard shield, it is characterized in that: the end that described clamp nut is arranged on the grinding roller axle is connected with the cross-arm axle bed; The bottom of described cross-arm axle bed interfixes through bolt and sealing shroud, on the step surface of described cross-arm axle bed and grinding roller axle the adjustment pad is installed; One end of described bearing upper press cover matches with the inwall of sealing shroud, and the upper end is also with oil sealing and grinding roller sealing in the described bearing upper press cover; The bottom of described bearing upper press cover is connected through bolt with roller leather sheet cover; Described oil sump fixes through oil sump clamp nut and Bearing housing; The outside of described oil sump adds the oil sump guard shield; Described grinding roller roller intracutaneous tapered hole is up-small and down-big formula and is anchored on the roller leather sheet through clamp nut and puts; The perforation oil circuit that is vertically arranged with diameter 20mm of described grinding roller axle is provided with the perforation oil circuit mouth that diameter is 8mm apart from its 1/3rd places, bottom.
The present invention has: simple in structure, safe in utilization, the life-span is long, the even advantage of wearing and tearing.
Description of drawings
Fig. 1 is a structural representation of the present invention
The specific embodiment
Below in conjunction with description of drawings the present invention is done further elaboration.
Fig. 1 is an optimal way of the present invention, and it has shown that the self-lubricating grinding roller comprises: clamp nut 1; Cross-arm axle bed 2, adjustment pad 3, sealing shroud 4; Bearing upper press cover 5, grinding roller axle 6, roller leather sheet cover 8; Grinding roller roller skin 9, oil sump 10 and oil sump guard shield 11 is characterized in that: the end that described clamp nut 1 is arranged on grinding roller axle 6 is connected with cross-arm axle bed 2; The bottom of described cross-arm axle bed 2 interfixes through bolt and sealing shroud 4, and adjustment pad 3 is installed on the step surface of described cross-arm axle bed 2 and grinding roller axle 6; One end of described bearing upper press cover 5 matches with the inwall of sealing shroud 4, and the upper end is with oil sealing 12 and 6 sealings of grinding roller axle in the described bearing upper press cover 5; The bottom of described bearing upper press cover 5 and roller leather sheet cover 8 is connected through bolt; Described oil sump 10 fixes through oil sump clamp nut 13 and Bearing housing 14; The outside of described oil sump 10 adds oil sump guard shield 11; Described grinding roller roller skin 9 internal taper holes are up-small and down-big formula and are anchored on the roller leather sheet cover 8 through clamp nut; The perforation oil circuit 15 that is vertically arranged with diameter 20mm of described grinding roller axle 6 is provided with the perforation oil circuit mouth 16 that diameter is 8mm apart from its 1/3rd places, bottom.
When equipment operation; The heat that is produced that rubs when internal bearings operation friction and grinding roller roller skin 9 and bull ring ground material makes oily temperature rise expanded by heating; The natural phenomena that colds and heat succeed each other makes lubricating oil throw to the lubricated position of whole needs to lubricating oil when rotated through connecting oil circuit 15 and the groove that connects oil circuit mouth 16 Automatic Cycle when alternately utilizing, oil sump 10 bottoms (groove this time be equivalent to an impeller), realizes self-lubricating.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equivalent variations and improvement of doing according to application range of the present invention are within the covering scope all of the present invention due to.
