Abstract
The utility model discloses a decelerator which comprises a driving bevel gear, a driven bevel gear, a driving helical gear, a driven helical gear, a connecting hub and conical roller bearings, wherein the driving bevel gear is installed on an electric output shaft and is meshed with the driven bevel gear, the driven bevel gear is fixedly installed at the front end of a driving helical gear shaft and is fixed through a stop nut and a gasket, the driving helical gear is meshed with the driven helical gear, and the middle of the driving helical gear shaft is supported and fixedly installed onto the connecting hub through two conical roller bearings. The decelerator solves the problems that the transmission ratio is small, the transmission is unstable, and the noise is high when the gear is meshed for transmission; and the decelerator has simple design, compact structure, a shorter suspension arm, longer support distance and good rigidity.
Description
Technical field
The utility model relates to the retarder technical field, specifically belongs to a kind of retarder of electric traction vehicle bridge case fork truck.
Background technique
Existing retarder, generally without continuous operation, work cell need have between the rest periods.Impact force and noise are big when transmission, and transmission is steady inadequately, and gear transmission is smaller, and engagement time is shorter; Retarder internal structure complexity, layout is reasonable inadequately, give after sale the maintenance band just, be used for the retarder of electric traction vehicle bridge case at present, does not still have the patent of being correlated with.
The model utility content
The purpose of this utility model provides a kind of retarder, and velocity ratio is little when having solved meshed transmission gear, the transmission instability, and the problem that noise is big, simplicity of design, the topology layout compactness, the shorter support interval of cantilever is longer, good rigidly.
The technical solution adopted in the utility model is as follows:
A kind of retarder, comprise active oblique gear, passive helical gear, active spiral gear, passive spiral gear, connect wheel hub, tapered roller bearing, active oblique gear is installed on the electronic output shaft and meshes with passive helical gear, described passive helical gear is installed in active helical gear shaft front end and fixes by stop-nut and packing ring, initiatively spiral gear and passive spiral gear engagement initiatively is installed in the connection wheel hub by two tapered roller bearings supports in the middle of the helical gear shaft.
Described active oblique gear and passive helical gear adopt the helical gear auxiliary driving.
Described active spiral gear and passive helical gear drive adopt the hypoid gear pair transmission.
The support pattern of described active spiral gear is a cantilever type.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model main reducing gear adopts the helical gear auxiliary driving, and double reduction adopts the hypoid gear pair transmission, has compact structure, operates steadily, and noise is little, good rigidly, life-span advantages of higher; Etc. connection and reasonable arrangement, compact structure, volume is small and exquisite, is convenient to manufacture and maintenance; The support pattern of active spiral gear is a cantilever type in the retarder, adopts two tapered roller bearings, and support interval is longer than lacking for cantilever, good rigidly is convenient to layout, the adjustment of gear pre-tightness and the lubricating of bearing of structure, and speed ratio is big, the transmission efficiency height has good power character and Economy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of retarder, comprise active oblique gear 1, passive helical gear 2, active spiral gear 3, passive spiral gear 4, connect wheel hub 5, tapered roller bearing 6, active oblique gear 1 is installed on the electronic output shaft 7 and adopts helical gear auxiliary driving engagement with passive helical gear 2, it is fixing by stop-nut 8 and packing ring 9 that passive helical gear 2 is installed in active helical gear shaft front end, initiatively spiral gear 3 adopts hypoid gear pair transmission engagement with passive spiral gear 4, initiatively the support pattern of spiral gear 3 is a cantilever type, initiatively is installed in connection wheel hub 5 by 6 supports of two tapered roller bearings in the middle of the helical gear shaft.
