Description
Technical field
The present invention relates to a kind of coupling, especially a kind of drum-type gear coupling.This drum-type gear coupling is particularly suitable for the power transmission between the traction electric machine and gear-box in the rail vehicle motor car bogie.
Background technique
In the motor car bogie that uses in rail vehicle, the power of its traction electric machine output is to be delivered to gear-box by a drum-shaped tooth type shaft coupling, and driving wheel is rotated again.The main feature of drum-shaped tooth type shaft coupling is to bear bigger load, and should have by a relatively large margin axially, radially, the compensation ability of angular displacement deviation.Therefore, between the end cap of this coupling and the internal tooth axle sleeve bigger interval to be arranged, usually drum-shaped tooth type shaft coupling adopts packing, keeps circle, baffle ring, rubber seal to wait the axial displacement that limits the internal tooth axle sleeve, and prevent that the lubricating grease in the coupling cavity from leaking, but the angular displacement deviation of its permission is little, working life is short, maintaining work is heavy, the user cost height, owing to can't prevent the intrusion of outside dust and water etc. reliably, may cause the lubricating grease inefficacy and inside and outside gear wear is quickened, coupling was lost efficacy.Application number be 97195363.5 adopt bellows as its assembly process complexity of Sealing in first to file " cog-wheel coupling ", in case occur damaging, change very difficulty.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the defective that sealing property of sealing component is bad, fragile and assembling is complicated, replacing is difficult of the drum-type gear coupling existence under the present prior art, the spy provides a kind of efficient sealed performance that has, the drum-type gear coupling that assembling simultaneously is simple, change convenient, reliability and durability Sealing.
The technical solution adopted in the present invention is: a kind of drum-type gear coupling, include the external tooth axle sleeve and the internal tooth axle sleeve of gear matched, and the end cap that is used to encapsulate, in the cavity that forms by external tooth axle sleeve, internal tooth axle sleeve and end cap, be provided with the flexible hollow tubulose Sealing that is used for end cover and internal tooth axle sleeve, described flexible hollow tubulose Sealing axial elasticity tensioner is between the inwall of internal tooth axle sleeve and end cap, and the two ends of hollow tubular Sealing cooperate with the inwall notch of internal tooth axle sleeve and end cap respectively.Both can further improve sealability by the notch cooperation, prevent the leakage of lubricating oil, and can also effectively limit the axial displacement of external toothing in coupling simultaneously, and make that the assembling of hollow tubular Sealing is very convenient.
The metal end plate that described hollow tubular Sealing is connected by hollow plastic pipe, built-in metal spring and metal spring two ends is moulded one and constitutes, to improve the reliability of Sealing.
Described hollow plastic pipe adopts teflon or nitrile butadiene rubber or contains fluorine rubber or resistance oil silicone rubber is made.
The metal end plate welding that described metal spring is connected with its two ends improves the reliability that connects, thereby improves the reliability of whole Sealing.
Described internal tooth axle sleeve has the guidance cavity of being convenient to suit hollow tubular Sealing, and it is good that the shape of guidance cavity is made cone shape.The existence of guidance cavity will make that the assembling of hollow tubular Sealing is more convenient, and Sealing is a pair of promptly accurate with the corresponding notch of internal tooth axle sleeve.Hollow tubular Sealing after packing into is put under the tight mating reaction of the tensioner effect of spring and two ends engagement groove within it, and two end face is restricted can't do rotation, offset movement in coupling.
The two ends of described hollow tubular Sealing have tongue, and the corresponding positions of internal tooth axle sleeve and end cap inwall is equipped with corresponding groove, and the concave, convex groove cooperates.This scheme can be more conducive to the assembling of hollow tubular Sealing.
The two ends of described hollow tubular Sealing all have the baffle ring that is posted by internal tooth axle sleeve and end cap respectively, hoop is with flexible dirt-proof boot on described internal tooth axle sleeve, dirt-proof boot has the shade ring, and the ring of shade ring is affixed on the baffle ring that is posted by the end cap inwall of hollow tubular Sealing along elastic top.The existence of dirt-proof boot can further effectively stop the water liquid of coupling outside, dust to enter in the coupling from the gap of coupling internal tooth axle sleeve and end cap, thereby protect coupling inside effectively, improves operational reliability.
Described dirt-proof boot adopts teflon or nitrile butadiene rubber or contains fluorine rubber or resistance oil silicone rubber is made.
The invention has the beneficial effects as follows: the hollow tubular sealing property of sealing component height that is adopted in this drum-type gear coupling, can effectively prevent the intrusion of the leakage of lubricant grease in the coupling and outside water liquid, dust, improve the working life and the operational reliability of coupling; Have simultaneously assembling simple and easy fast, not easy to wear, change outstanding easily advantage, and can also effectively limit the axial displacement of external toothing in coupling.This drum-type gear coupling is specially adapted to the power transmission between the traction electric machine and gear-box in the rail vehicle motor car bogie.
