The schematic perspective view of the transmission device (16) of Fig. 3 the utility model device;

Fig. 4 be A in Fig. 1 to view, represented the layout of nozzle assembly;

Referring to Fig. 1-4, wherein the name of piece number is called:

1 body of heater; 2 heater elements; 3 bearings; 4 raceways; 5 frames; The I jacking mechanism; Jacking mechanism I comprises: 6 cylinders, 7 driving levers, 8 columns, 9 connecting rods and 10 push rods; The II jacking mechanism; Jacking mechanism II comprises: 11 cylinders, 12 driving levers, 13 columns, 14 connecting rods and 15 push rods; 16 tourelles; 17 grease removal stations; 18 electro heat stations; 19 bearing support; 20 driven vollers; 21 drive rolls; 22 driven sprockets; 23 chains; 24 drive sprockets; 25 transmission systems; 26 back flap nozzle groups; Flap nozzle group before 27; 28 side static jet groups, 29 preceding static jet groups; 30 blower fans;

1-4 describes the utility model in conjunction with the accompanying drawings; Electric heater unit is a low temperature electric furnace, and body of heater 1 is an oblong, is fixed on the support 5, and body of heater two ends have the import and the outlet that can supply bearing 3 to pass through; Raceway 4 passes burner hearth central authorities, and its two side exceeds, and makes of the channel-section steel that has the gradient.Bearing 3 can be on raceway 4 rolls forward automatically, and the import of the entrance point of raceway and exit end and body of heater and outlet are mated, and its terminal rail face is provided with opening, is stuck, locatees, heats and by jack-up for bearing; Blower fan 30 is equipped with on top in body of heater (1), with temperature in the balance stove; The purpose of heating bearing makes grease softening, increase flowing power, be convenient to remove grease, according to ambient temperature, season, grease classification and period of service length, heating-up temperature can change in 80-200 ℃, preferred heating-up temperature is in 100-180 ℃ of scope, temperature is by the attemperating unit automatic guidance in the stove, can be simultaneously on the raceway 4 in the body of heater with bearing (the external diameter φ 180-340 millimeter of 3 different sizes, wide 65-110 millimeter) heat, bearing time of heat in stove just determines according to above-mentioned heating-up temperature.

Bearing jacking mechanism I is housed below the end openings place of raceway 4, it is made of cylinder 6, driving lever 7, column 8, connecting rod 9 and push rod 10, cylinder 6 and column 8 are fixed on the bottom of frame 5, and push rod 10 is supported by driving lever 7 and connecting rod 9, and it is hinged to be B point and C point.Connecting rod 9 other ends are articulated in the D point in column, and the piston rod of the other end of driving lever and cylinder 6 is articulated in the A point, and the fulcrum of driving lever is and column 8 pivotally attached O points.When bearing 3 is heated, during the work of grease removal station, piston rises, and driving lever 7 rotates around fulcrum O, and A point lifts, and B point descends, and drives push rod decline, and (spacing) blocked by the opening of the end of raceway 4 in the lower end of bearing 3, and bearing stops rolling; When bearing is ejected the machine except that intact grease, after the room appears in the grease removal station, corresponding bearing 3 on the heating station raceway 4 is heated to predetermined temperature, piston by the jacking mechanism I of time relay control is pulled back, driving lever 7 rotates around fulcrum O, the A point descends, the B point rises, the drive push rod rises, the lower end of bearing is pushed up to being higher than the raceway track upper surface, because the push rod upper surface has certain slope along the bearing element direction, after bearing rolled on the tourelle 16 of grease removal station 17 automatically forward, push rod descended.Next bearing rolls forward automatically again and enters opening part, continues heating.

The body latter half is a grease removal station 17, and the grease that is softened on the heating rear bearing is eliminated at this place.At this station, be provided with bearing element mechanism 16, nozzle system III, jacking mechanism II.Transmission system rotates by chain-driving drive drive roll 21, and bearing 3 is being gone up slow rotation by the two rollers that rotate (two rollers are installed at grade for drive roll 21, driven voller 20), is distributed in bearing 3 nozzle on every side softening grease is blown down.

Nozzle system III is made up of preceding static jet group 29, side static jet group 28, preceding flap nozzle group 27 and back flap nozzle group 26, they be distributed in bearing element mechanism 16 around, eject the gas that 0.2-0.5MPA is with pressure from different angles to bearing, force grease to split away off from bearing body.Preceding static jet group 29 is made up of 3 nozzles, mainly finishes the intersection point jet band pressed gas common to the retainer gap of different size bearing 3, to remove bearing in-to-in grease; Side static jet group 28.Forms by left and right each nozzle, mainly finishes bearing top circle face and driving and driven

roller

21,20 surperficial contact wires are jetted, with removing bearing and two roller surfaces with grease; Before flap nozzle group 27 and back flap nozzle 26 form by two nozzles respectively, preceding flap nozzle 27 is done oscillating type and is pumped under the eccentric drive in front on 21 of the drive rolls.Back flap nozzle group 26 is done straight reciprocating motion up and down through four-bar linkage under the back eccentric drive on the initiative roll shaft.Forward and backward flap nozzle group is mainly finished the winding-up band pressed gas to forward and backward two side (standing) faces of bearing body 3 and retainer inner ring face and surface of beads repetition, to remove its lip-deep grease, because bearing body 3 rolling at a slow speed and the reciprocal winding-up of forward and backward two flap nozzle groups on rolling mechanism, not only overcome static jet blow less than the dead angle, and enlarged the winding-up face of bearing body.Can finish winding-up comprehensive to bearing integral, that repeat, make the grease on the bearing body, cleaner from the inside to surface, be eliminated completely.

The structure of jacking mechanism II is identical with jacking mechanism I.When the bearing body grease be eliminated finish after, push rod 15 rises, and with bearing 3 jack-up, makes bearing roll out grease removal station 17 automatically, leaves body and enters subsequent handling.

The process of removing bearing grease is described below:

Dirty bearing 3 is sent into the inlet of body of heater 1, roll into the top of raceway 4, because raceway 4 has the gradient, bearing is under the effect of weight, the end that is rolled into raceway 4 forward is stuck, do not rolling, electrical heating elements 2 heats up and heats bearing body, when bearing body is heated to preset time, bearing 3 is by push rod 10 jack-up of jacking mechanism I, bearing 3 roll into tourelle 16 in the grease removal station 17 two rollers (drive roll 21 and driven voller 20) between, transmission system 25 drives drive sprockets 24, chain 23, sprocket wheel 22, driving drive roll 21 rotates, rotate thereby drive bearing 3, through being arranged on the fixing of nozzle system III around the bearing 3, the flap nozzle group is jetted under the effect of the band pressure air that, makes to heat the grease that is softened and split away off, push rod 15 by the jacking mechanism II of time relay control rises, will be except that the bearing jack-up of intact grease, bearing rolls out grease removal station 17, leaves body and enters subsequent handling.

This device technique process is simple, can use separately, also can with the follow-up supporting use of operation (cleaning, rust cleaning etc.).
