Description
Technical field
The utility model belongs to speed reducer, particularly relates to three grades of transmission cylindric spiral gears of a kind of parallel axes speed reducer.
Background technique
At present, in the known all kinds of speed reducers in the whole nation, under the identical situation of output torque, desire will strengthen reduction speed ratio, and then the volume of casing must strengthen, and promptly the whole volume of speed reducer will increase.For example, known PM speed reducer, seek out the large speed ratio (i=229) of equal-wattage, because of each transmission shaft in its casing is the narrow limitation of planar alignment, when the output torque is identical, want to strengthen reduction speed ratio, then not only volume is bigger for speed reducer, and work is not steady, and vibration and noise are bigger, temperature rise is increased, its working life is shorter, and the classification of velocity ratio is big at interval, simultaneously, owing to be subjected to the restriction of installation form, the user can only be provided a kind of lower margin mounting type, can not satisfy the demand of the multiple installation pattern of user, at this moment, can only select external gear reduction unit for use, but price is very expensive.
Summary of the invention
The utility model provides three grades of transmission cylindric spiral gears of a kind of parallel axes speed reducer for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Three grades of transmission cylindric spiral gears of parallel axes speed reducer, form by motor, input small gear, input gearwheel, casing, intermediate speed pinion axle, gear broad in the middle, output pinion axle, output gearwheel, output shaft, flange plate, bearing, oil sealing, back-up ring, oil seal ring, key and fastening piece, it is characterized in that: motor is packed on the input side of casing by blind flange and fastening piece, the output shaft of motor installs an input small gear that cover is wheeled by key, input pinion input gearwheel; The input gearwheel is packed in by key on the middle part pillow block of intermediate speed pinion axle, and an end of intermediate speed pinion axle is pedestal and bearing is housed that the intermediate speed pinion of its other end meshes gear broad in the middle; Gear broad in the middle is packed in by key on the middle part pillow block of output pinion axle, and an end of output pinion axle is pedestal and bearing is housed, the output pinion engagement output gearwheel of its other end; The output gearwheel is packed on the middle part pillow block of hollow output shaft by key, the two ends of output shaft are fixed with spring bearing respectively, the outer ring of two bearings is installed in respectively in the forward and backward bearing chamber of casing, and the outside of two bearings is equipped with hole back-up ring, oil sealing and oil seal washer respectively; Upper end at casing is provided with suppending hole, installs a flange plate at the also available fastening piece of the output terminal of casing.Wherein, the output shaft of motor, intermediate speed pinion axle, output pinion axle and output shaft, the line of four axis points in side view is " Z " font layout in the space.
The utility model can also adopt following technical measures:
Described input small gear, input gearwheel, intermediate speed pinion, gear broad in the middle, output pinion, output gearwheel are the hard flank of tooth of helical gear, high-strength wear-resistant alloy.
Advantage and the good effect that the utlity model has are: the small gear on the motor output shaft, structurally adopt wheel but not one, and can reduce the kind of motor like this.All driving gears are helical gear, and employing high-strength wear-resistant alloy, has the hard flank of tooth, so its bearing capacity is strong, transmitting torque is big, wear-resisting property good, long service life, stable drive, vibration and noise is little, temperature rise is low, efficient is high, the power range of this speed reducer big (0.18～75kW), the span of reduction speed ratio big (4～229), speed ratio be little (I to 1) at interval, compare with the PM speed reducer of same size, the volume of this speed reducer can reduce 30%, weight saving 40%.Four axles of the present utility model: the output shaft of motor, intermediate speed pinion axle, output pinion axle and output shaft, the line of four axis points in side view, be " Z " font layout in the space, because the said gear axle is rationally distributed, make complete machine compact structure, to have a volume little, in light weight, and can at less input and output center in scope, realize the configuration of large speed ratio.When mounted, save the spatial position, except traditional fixed installation form, also can be suspended on the working host, and can move with working host by the suppending hole on the casing.Also can provide multiple Placements such as flange plate type, solid output shaft type, hollow output shaft (containing spline hollow shaft and locking plate hollow shaft) formula to the user.Along with adjustment, mounting type of the present utility model is also had: to crouch, bow, face upward, 7 kinds of installation forms such as extension, to satisfy user's multiple demand to abat-vent, plug screw and oil sight device mounting point.
