Abstract
A grinding wheel transmission mechanism of a vertical grinding machine with double end faces is characterized in that a projection of a spindle is inserted into a cross slot of a concave ring of a coupling joint from bottom to top, and a projection of the coupling joint is inserted into a cross slot on the other side of the concave ring of the coupling joint from top to bottom. The upper portion of the spindle is in threaded connection with a ring nut, a taper roller bearing is sleeved on the upper portion of the spindle, a deep-groove ball bearing and an angular contact bearing are overlapped and sleeved on the lower portion of the spindle, and a grinding wheel fixing disc is fixed at the bottom of the spindle through bolts. A projection ring is arranged in the middle of the inner wall of an outer tube so that an upper step and a lower step are formed to serve as bearing seats, the bearing seats surrounds the outside of the spindle, a plurality of screw holes are arranged on the periphery of the upper portion of the outer tube so that the outer tube can be fixed onto a motor flange plate by screws conveniently, and the motor flange plate is fixed on a framework. A grinding wheel is fixed on the grinding wheel fixing disc through glue or studs. When the projection of the coupling joint rotates, the spindle is driven to rotate with the grinding wheel together by the concave ring of the coupling joint. The bending moment of a transmission shaft can be avoided by means of the coupling joint type transmission, and accordingly balance performance and grinding precision of the grinding wheel are improved.
Description
Technical field
The present invention relates to metal cutting machinery field, relate to the emery wheel transmission mechanism of Double End vertical grinder specifically.
Background technology
Vertical grinder all adopts emery wheel as cutting tool; Because rotating speed is very fast, thus quite high to the dynamic balance accuracy requirement of emery wheel, otherwise vibration will appear in rotating speed slightly soon; It is not high that the insider is called " critical speed ", and its direct result is exactly that grinding accuracy is poor, grinding efficiency is low.
The emery wheel of prior art most employing belt transmission or the direct transmission of electric machine main shaft; Belt transmission then produces amount of deflection to grinding wheel spindle, and the overstriking diameter of axle of having to is to increase rigidity; If grinding wheel spindle directly is fixed on the electric machine main shaft, then both axialities are difficult to guarantee, need increase substantially the accuracy of manufacture and installation accuracy, and manufacturing cost is high.
The emery wheel power transmission shaft front end of prior art and the endoporus of emery wheel fixed disk often adopt circular cone to cooperate; Circular cone is cooperated work, its length of fit must be longer, causes the distance of transmission shaft bearing supporting-point and emery wheel center of gravity far away; Jib-length is big, and " critical speed " is not high.Keep technology necessary " critical speed ", also get the overstriking diameter of axle and strengthen bearing specification, cause manufacturing cost to improve precise decreasing.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, develop the emery wheel transmission mechanism of the Double End vertical grinder of a kind of critical speed height, low cost of manufacture,
The present invention is achieved through following technical proposals:
The emery wheel transmission mechanism of Double End vertical grinder comprises motor flange dish, the protruding circle of shaft coupling, the recessed circle of shaft coupling, nut ring, urceolus, main shaft, tapered roller bearing, deep groove ball bearing, angular contact bearing, emery wheel fixed disk, emery wheel;
Arc-shaped convex above the main shaft is inserted in the cross recess of the recessed circle of shaft coupling from the bottom up, and the shaft coupling convexity is inserted in the cross recess of the recessed circle opposite side of shaft coupling from top to bottom; Main shaft top and nut ring are threaded, and tapered roller bearing is being overlapped on main shaft top, and the outer ring of taper roll bearing is shelved on urceolus tops bar, and the inner ring upper surface of taper roll bearing heads on the nut ring; The deep groove ball bearing and the angular contact bearing of superimposed placement overlapped in the bottom of main shaft, and the upper surface, outer ring of deep groove ball bearing heads on getting out of a predicament or an embarrassing situation of urceolus; The upper end of angular contact bearing outer ring heads on the deep groove ball bearing lower surface, and the inner ring lower surface heads on the main shaft step; The main shaft bottom with bolt the emery wheel fixed disk;
Have a circle protruding in the middle of the outer tube inner wall, the twice step is wrapped in the main shaft outside as bearing block about forming, and is provided with several screws around the urceolus top, is convenient to be fixed on urceolus on the motor flange dish with screw, and motor is installed on the ring flange;
Emery wheel is fixed on the emery wheel fixed disk with glue or double-threaded screw.
Be provided with a macropore in the middle of the top of main shaft, hold possible the stretching into of power transmission shaft; Be provided with a circle aperture around the hole; Be provided with tapped through hole on the nut ring and be uniformly distributed with several apertures; Stretch into specific purpose tool in several apertures of nut ring and can rotate nut; The adjustment taper roll bearing tightness, adjust suitable after, on tapped through hole with screw clamping rings hook; Stretch into the elbow part of annulus hook in certain aperture on main shaft top, use preventing thread looseness.
Advantage of the present invention is: owing to adopted the shaft coupling type transmission, reduced the accuracy of manufacture and installation accuracy, the emery wheel power transmission shaft is not had moment of flexure.Because main shaft has adopted form of flanges to be connected with nethermost bearing with abrasive disc and has selected bigger angular contact bearing for use, realized that point of resultant force approaches to overlap with the emery wheel center of gravity, and three bearings that overlapping on the main shaft have been the equal of three point supportings to it; Bearing strength is better, has increased the main shaft rigidity, and the grinding wheel dynamic balance performance is good; Make it under same shaft length situation; Can subtract the diameter of axle carefully, reduce the bearing type selecting, and the emery wheel rotation is more steady.
