Background technology
At present, many employing copper cover sealings between amplitude modulation case tentering axle and amplitude modulation casing, between overlapping by tentering axle and copper, slide control is significantly small size, and existing tentering axle surface smoothness, by the restriction of lathe precision, does not reach and the standard of amplitude modulation casing precision-fit, poorly sealed, leakage of oil is serious, causes oil product to waste, and long-term oil spill infiltrates Equipment Foundations and also can equipment foundation be damaged, the firm property of equipment is deteriorated, aggravation structure deteriorate; Simultaneously owing to tentering axle and amplitude modulation casing belong between metal the reciprocating friction between hard, serious wear, along with the extension of duration of service, tentering axle and amplitude modulation casing tolerance clearance become big gradually, leakage of oil aggravates, and forms vicious cycle, it is necessary to often shuts down and changes tentering axle and copper cover, add material cost and maintenance mans' labour intensity, affect output; Oil spill makes device context environment become severe, also creates disaster hidden-trouble. How making and sealing between tentering axle and amplitude modulation casing can be made to reach equipment operating requirement, moreover it is possible to prevent the generation causing oil leakage phenomenon because it is poorly sealed, the amplitude modulation case reducing material maintenance cost and maintenance labour intensity is the problem needing to solve.
Practical novel content
Technical problem to be solved in the utility model is: provide a kind of amplitude modulation case. Use this amplitude modulation case that sealing between tentering axle and amplitude modulation casing can not only be made to reach equipment operating requirement, and the generation causing oil leakage phenomenon because it is poorly sealed can also be prevented, reduce material maintenance cost and maintenance labour intensity.
The technical scheme that the utility model solves the problems of the technologies described above is: a kind of amplitude modulation case, comprise amplitude modulation casing, tentering axle, it is characterized in that: also comprise amplitude modulation casing and tentering shaft sealing device, described amplitude modulation casing and tentering shaft sealing device comprise with amplitude modulation casing with the use of ring flange, guiding band, sealing-ring, O, lattice orchid circle, dustband, the side plate of described amplitude modulation casing side is provided with circular through hole, described ring flange has the part stretching on this side plate the circular through hole arranged and stretching out circular through hole and the part abutting in side plate around circular through hole, this ring flange stretches into described circular through hole and stretches out the external diameter of circular throughhole portions consistent with the diameter of this circle through hole, the part use at least 5 that described ring flange abuts in side plate around circular through hole is bolted on this side plate, described ring flange stretches into this circle through hole and stretches out the internal diameter of circular throughhole portions consistent with the diameter of tentering axle, and this ring flange stretches into circular through hole and stretches out and be disposed with lead band, sealing-ring, O, Ge Lanquan, dustband on the internal surface of circular throughhole portions from inside to outside, described tentering axle sleeve be connected to be disposed with from inside to outside guiding band, sealing-ring, O, Ge Lanquan, dustband this ring flange stretch into circular through hole and stretch out on the internal surface of circle throughhole portions,
Described tentering axle surface is provided with chromium coating;
Described ring flange stretches into circular through hole and stretches out the circular outside surface of throughhole portions and the internal surface of this circle through hole is shrink-fit.
The beneficial effects of the utility model are: be provided with amplitude modulation casing and tentering shaft sealing device due to the utility model, the ring flange of amplitude modulation casing and tentering shaft sealing device stretches into circular through hole and stretches out and be disposed with guiding band on the internal surface of circular throughhole portions from inside to outside, sealing-ring, O, lattice orchid circle, dustband, by the guiding band of setting on ring flange internal surface between tentering axle and amplitude modulation casing, sealing-ring, O, lattice orchid circle, the sealing of dustband, overcome the Leakage due to poorly sealed appearance between existing amplitude modulation case tentering axle and amplitude modulation casing, improve device context Working environment, eliminate the disaster hidden-trouble caused because of leakage of oil, simultaneously tentering axle greatly slightly regulate process also tentering axle can not be caused abrasion, add the work-ing life of tentering axle, decrease fault power time, it is to increase product production, decrease maintenance cost, reduce maintenance work working strength.
Again owing to being provided with chromium coating on the surface at tentering axle, it is to increase tentering axle surface smoothness, achieve the sealing effect of better amplitude modulation casing and tentering axle.
