Description
Technical field
The present invention relates to press machine accessory technical field, especially a kind of leak-proof arrangement of wet clutch flywheel rear portion.
Background technique
Mechanical press is widely used in the industries such as automobile, household electrical appliances, shipbuilding, five metals, elevator, electric cabinet, instrument.The existing most air operated friction clutch/break that adopts is as the important component part of main transmission, and wet clutch/break is compared dry clutch and had more good environmental protection, and noise is low, durability advantages of higher and being widely used.But for a long time, wet clutch/break both domestic and external exists a major defect, after namely using a period of time, its flywheel and off-load place there will be leakage of oil, have a strong impact on using effect.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of wet clutch leak-proof arrangement rational in infrastructure, thus effectively can reach the effect of oil-leakage-prevention.
The technical solution adopted in the present invention is as follows:
A kind of wet clutch leak-proof arrangement, comprise tooth axle, described tooth axle is provided with unloading sleeve by clutch shaft bearing, one end of described unloading sleeve is provided with step, the First terrace of described unloading sleeve is provided with rotary oil seal by lining, the second step face of described unloading sleeve is provided with flywheel by the second bearing, flywheel closely cooperates with the outer ring of rotary oil seal simultaneously, described flywheel is provided with compensating groove, described compensating groove is between rotary oil seal and the second bearing, be positioned at compensating groove and grease baffle is installed, second bearing one end is close to by described grease baffle, the other end of described second bearing is also provided with bearing cover, described bearing cover is fixed on flywheel by fastening piece, described flywheel has the pod apertures be obliquely installed, one end of described pod apertures is communicated with compensating groove, the other end of described pod apertures and the inner space of flywheel, the second step face of described unloading sleeve is also provided with brake disc.
Further improvement as technique scheme:
Described flywheel circumferentially have two pod apertures, the angle between described pod apertures and horizontal plane is 45 °;
Described rotary oil seal is integral type structure, and one end of described rotary oil seal has U-shaped groove;
The First terrace of described unloading sleeve and lining adopt interference fit.
Beneficial effect of the present invention is as follows:
Compact structure of the present invention, rationally, operation is with easy for installation, by the unique design to flywheel, according to the principle of centrifugal force, adopt compensating groove and pod apertures structure, guide the fluid of wet clutch inside be introduced into compensating groove by leakage (rotary oil seal place) and by compensating groove in some pod apertures, under centrifugal action, flow back to flywheel inner chamber, thus guarantee fluid can not because of rotary oil seal is unreliable or wearing and tearing, aging after and lost efficacy and caused fluid spill and leakage.Guarantee can not leak into outside flywheel, using through reality proves, the method is reliable, practical, and it is lower to increase cost.
