The utility model adopts a two-stage decelerating transmission with concentric input and output gears and is small in size, which can reduce the weight of the vehicle and has greater loading capacity under the condition of same power from an electromotor; a gear chamber is sealed and can be filled with butter so as to achieve good lubrication; the gear has low abrasion and noise; the structure of the hub drive device is simple in structure, which simplifies assembling process and reduces cost.
Description
Technical field
The utility model relates to electric driver, particularly a kind of gear reduction hub drive device that is used for electric bicycle or battery-operated motor cycle.
Background technique
The motor wheel hub drive unit of electric bicycle of the prior art or battery-operated motor cycle, more have two kinds of structural types, and a kind of is the side that motor is installed in wheel shaft, and the transmission device volume is big, and mechanical parts are many, complex structure, poor lubrication; Second kind is that motor shaft is concentric with wheel hub, rotate by the ring gear drive hub by the planetary reduction gear transmission device, this structure radial dimension is bigger, it is high that the requirement of concentricity requires processing and installation precision, the cost of production height, fast for the Nylon gear wear that noise-decreasing adopts, working life is short.
The model utility content
The utility model purpose be improve bearing capacity for electric bicycle or battery-operated motor cycle provide a kind of, reduce mechanism, reduced volume, reduce cost, the gear reduction hub drive device of long service life.
The utility model indication gear reduction hub drive device, mainly comprise wheel hub and wheel hub back shaft, the rotor DC machine tubular axis outer with being enclosed within back shaft that is arranged in the wheel hub is connected, the clutch end of tubular axis is shaped on small gear, it is characterized in that the gearwheel engagement of this small gear and coaxial two-gang gear, the small gear of coaxial two-gang gear and output gear engagement, output gear is concentric with above-mentioned small gear, output gear drives right end cap and rotates, and the inner ring of the left end cap of drive unit and right end cap and wheel hub is connected.
Between back shaft and tubular axis, output gear, two bearings are housed respectively, a bearing is housed between the right end cap of back shaft and drive unit, back-up ring is arranged between each bearing every putting.
The above-mentioned bearing that is contained between output gear and the gear chamber right end cap is the stuffing box bearing with seal ring.
Double crosslinking gear shaft passes through the needle bearing bearing between motor room's right end cap and gear chamber right end cap.
Motor room's right end cap and motor casing are made one.
The gear chamber right end cap can be installed a grease nipple.
The utility model and existing electric bicycle or battery-operated motor cycle drive unit are compared advantage and are: adopt input and export concentric double reduction transmission, volume is little, especially radial dimension is little, the car body weight reduction, and bearing capacity is big under the same motor power situation; Gear chamber sealing, but filling butter, lubricating condition is good, and gear wear is low, and noise is low; Structure is comparatively simple, and packaging technology is simplified, and cost reduces.
