Description

A kind of power homonymy input and output planetary reducer
Technical field
The present invention relates to a kind of new construction mechanical deceleration device field, specifically a kind of power homonymy input and output row Star gear reduction unit.
Background technology
Decelerator is served to slow down between power source and power output terminal and increases the effect turned round, in modern mechanical extensively Using.Planetary gear has the advantages that small volume, compact conformation, large carrying capacity, light weight compared with fixed axis gear, especially fits Close equation motorcycle race.But due to the restriction of oil filling amount, and the original such as bearing lubrication difficulty thus results in lubricating system and needs Redesign.The reasons such as the motor arrangement space and driveline arrangement narrow space due to the pure electronic racing car of equation are right Also there is certain requirement in planetary power input and output direction；Further, since the design of part of planetary reducer is answered As many as miscellaneous and number of parts, so feature contacts position is just corresponding to become many, causes CONTACT WITH FRICTION area to increase, and planet tooth Wheel work operating mode mostly is high rotating speed running, so transmission efficiency just receives certain impact, so to the contact between part Requirement also has certain requirement；Further, since planetary high speed rotation, internal quantity of heat production is big, and also has lubrication dead angle, This just has higher requirement to lubricating system and cooling system.
The content of the invention
Deposited when running up according to motor arrangement space and driveline arrangement narrow space, planetary gear set forth above In technical problems such as lubrication dead angles, and provide a kind of power homonymy input and output planetary reducer.Main utilization of the invention Motor input shaft and output shaft overlap mode are arranged and lubricating oil fueling injection equipment coordinates with decelerator, so as to reach compact conformation, High lubricating effect and other effects.
The technological means that the present invention is adopted are as follows：
A kind of power homonymy input and output planetary reducer, including planetary gear reducing mechanism, thermostat And fueling injection equipment, it is characterised in that：
The center of the planetary gear reducing mechanism is input shaft, and sun gear is nested with after the input shaft by spline End, is mutually supported and mutual between the front end of the input shaft and output shaft by two needle bearings and glue lid deep groove ball bearing Separate, make the work of the two non-interference；Planetary gear and the cooperation of sliding bearing gap, planetary gear tie-rod axle and the slip Bearing interference fit, the planetary gear tie-rod axle respectively will be described with front carrier flange and rear carrier flange interference fits Planetary gear is fixed on the outside of the sun gear；The front carrier flange is inlayed with the rear carrier flange and is connected, and Fixed with bolt in junction, the rear carrier flange is connected by deep groove ball bearing II with the input shaft rear end, described Front carrier flange is inlayed for interference with the rear end of output shaft and is connected, and blending bolt is fastened；The planetary gear outer sheath It is equipped with ring gear, the ring gear external diameter is provided with the internal spline that external splines arranges with rear half casing and matches, the ring gear With the rear half casing interference fit, the rear half casing is by deep groove ball bearing III and the rear carrier flange phase Even；The output shaft is connected by deep groove ball bearing I with front half casing, and the front half casing and the rear half casing are logical Cross red copper gasket seal II to be connected；The front end of the output shaft is sealed by drive end bearing bracket, and the front half casing passes through middle end cap Sealing, the rear half casing is sealed by rear end cap；
The thermostat includes the temperature sensor being integrated in the bleeder plug of the fueling injection equipment, the oil spout The flowline of device is also integrated in the bleeder plug, the flowline and lubricating oil pump, oil filter and oil cooler phase Even, then it is connected on bearing oil spray plug for milling machine by the petroleum pipeline being connected with the oil cooler, the bearing oil spray plug for milling machine is described by being arranged on Afterwards the oil-in of half casing upper end is connected with the planetary gear reducing mechanism, realizes circulation, cooling and the spray of lubricating oil, Bearing oil spray plug for milling machine spray oil be it is uniform, and bearing oil spray plug for milling machine be arranged in the top of rear half casing i.e. gear lubrication deficiency where.
Further, the planetary gear tie-rod axle with the rear carrier flange by being arranged on the epicyclic train The spring collar of bar shaft tail end limits axially-movable, and the planetary gear tie-rod axle is limited with the front carrier flange by boss Axially-movable processed.
Further, the needle bearing between the input shaft and the output shaft uses grease lubrication, the planet The remaining parts of gear reduction unit use oil lubrication, the input shaft to pass through II point of sealing lip with the front end of the output shaft Every the input shaft is separated with the rear end of the output shaft by glue lid deep groove ball bearing so that two kinds of lubrication forms are not mutually done Relate to.
Compared with the prior art, the homonymy that the present invention adopts the input shaft mode Chong Die with output shaft to realize power is input into Output.Wherein：The power of motor output shaft passes to sun gear by input shaft input, then is delivered to planetary gear by sun gear, Again front carrier flange is passed to by planetary gear tie-rod axle, then to output shaft, so spread out of power (ring gear is maintained static, with Afterwards half casing is connected).Needle bearing is used between input shaft and output shaft and then both work has been separated, made tool Both mutual when working for having different rotating speeds are not disturbed (the two rotating speed is different)；The present invention has thermostat and oil spout simultaneously Device, is automatically controlled by temperature sensor with single chip control unit.
The present invention has small volume, and compact conformation, light weight, lubrication state is good, and efficiency high is adapted to the arrangement of driving-chain And the advantages of part long service life.
