Description
Technical field
The utility model is related to a kind of wheel-chair reduction boxes.
Background technology
Driving motor is often used together with reduction box, to ensure the sealing of grease in reduction box, is needed in driving motor
Setting oil sealing in bearing chamber where shaft.Be equipped with more universal driving shafts in reduction box, on universal driving shaft and shaft axis mate gear with
Realize the linkage of shaft and output shaft, gear easily beats to contact with oil sealing so that the fixing seal effect of oil sealing is simultaneously unstable
It is fixed.
Invention content
The purpose of this utility model is to provide a kind of wheel-chair reduction box for being avoided that oil sealing and being damaged.
To achieve the above object, the utility model adopts the following technical solution：A kind of wheel-chair reduction box, including babinet,
Motor case is equipped on rear side of the babinet, cabinet front is equipped with case lid, and there are one assemble to be formed with case lid cooperation for the babinet
Space, the babinet have the clutch shaft bearing room for coordinating shaft, and the clutch shaft bearing room is by the first ring portion, the second ring portion structure
Internal diameter into, first ring portion is more than the internal diameter of the second ring portion, is fixed with clutch shaft bearing in first ring portion, and described second
Oil sealing is equipped in ring portion, the front end of the shaft sequentially passes through clutch shaft bearing and oil sealing to extend in assembly space, the case
Second bearing room is formed on lid and babinet, second bearing is fixed in the second bearing room and is combined with output shaft, is exported
The front end of axis passes through second bearing room to extend on front side of case lid, and the first transmission gear is fixed on the output shaft, and second passes
Moving gear and the first transmission gear link, and second transmission gear is fixed on universal driving shaft, and the babinet and case lid are respectively formed
There is 3rd bearing room and be fixed with 3rd bearing, the inner ring of the both ends of the universal driving shaft respectively with a 3rd bearing is fixed, institute
It states the gear hobbing of shaft front end and is engaged with second transmission gear.
The utility model is by setting the step structure of the clutch shaft bearing room of babinet, so that the fixation of clutch shaft bearing and oil sealing
Effect is more preferable, is located on front side of oil sealing to be formed between the second transmission gear and oil sealing by the second transmission gear for making universal driving shaft
Relatively large distance, to avoid oil sealing because the bounce of the second transmission gear is impaired；Wherein, since shaft front end passes through clutch shaft bearing and oil sealing
To extend in babinet so that shaft front end does not have boss, so that tooth longer at energy rolling in shaft, so that the second driving cog
Wheel can well be engaged with the dental transition in shaft, to improve transmission effect, and reduce noise, and stability is more preferable.Wherein, this practicality is new
The case lid of type is also used as the end cap of motor, to reduce the volume of motor and reduction box.
Preferably, the universal driving shaft deviates the part gear hobbing of rear end and engaged with the first transmission gear, described first passes
Moving gear is located on rear side of second transmission gear.Above-mentioned setting is so that the smaller that babinet can be done.
Preferably, the babinet is formed with the third ring portion on front side of the second ring portion, third ring portion internal diameter is less than the
Two ring portion internal diameters are to be formed with step structure.Oil sealing front end face is made to be formed with step structure with the second ring portion and third ring portion to connect
It touches, so that the fixation of oil sealing is more stable.
The utility model have be avoided that oil sealing be damaged, be driven effect smaller, volume smaller, noise be relatively low, stability more
The advantages of good.
