Abstract
The utility model relates to a transmission gear, in particular to a speed reduction and torque rise mechanism. The transmission gear comprises a brake drum, a hub, a half shaft, a spline housing, a gear ring rack, a check ring, a gear ring, a sun wheel, a planet carrier, a planet gear shaft, a planet gear, an end cover and a floating oil seal. The brake drum is fixedly connected with the hub, the check ring is fixedly connected with the spline housing, and the gear ring rack is fixedly connected with the spline housing. The gear ring is fixedly connected with the gear ring rack. The sun wheel is fixedly connected to the half shaft, the planet gear shaft and the planet carrier are connected in a rotating mode, and the planet gear is fixedly connected with the planet gear shaft and is meshed with the sun wheel and the gear ring. The planet carrier is fixedly connected with the hub, the hub is connected with the spline housing in a rotating mode, and the floating oil seal is arranged between the inner side of the hub and the spline housing. The end cover is fixedly connected with the planet carrier. The end cover, the planet carrier, the hub and the floating oil seal define a sealing cavity together. The transmission gear is large in traction, large in total reduction ratio, compact by the adoption of a planet gear type transmission structure, small in overall size, not prone to leaking oil in enclosed drive and long in service life.
Description
Technical field
The utility model relates to a kind of transmission device, and especially a kind of deceleration increases the mechanism of turning round.
Background technique
The mechanism that some agricultural machinery or engineering truck finally all need the increasing of slowing down to turn round as tractor, road roller etc. in its transmission system at present, object is to strengthen the total reduction speed ratio of power train, meet travelling and going requirement of complete machine, the transmission system of existing the increasing torsion effect that slows down mostly adopts externally-engaged cylindrical gear formula structure, overall dimensions is large, easy oil leakage, total reduction is smaller.
Model utility content
The utility model is intended to address the above problem, a kind of transmission device is provided, its tractive force is large, total reduction speed ratio is large, adopt planetary gear type drive mechanism compactness, overall dimensions is less, for not easy oil leakage of closed-type cylindrical gearing, long service life, its technological scheme adopting is as follows: a kind of transmission device, comprise: brake drum, wheel hub, semiaxis, spline housing, gear ring frame, back-up ring, gear ring, sun gear, planet carrier, planet pin, planetary pinion, end cap and float grease seal, described brake drum and wheel hub Joint, described spline housing and driving axle housing Joint, described shield ring sleeve is loaded on semiaxis and by screw and spline housing Joint, described gear ring frame be set on spline housing and with spline housing Joint, described gear ring and gear ring frame are by spline Joint, described sun gear is fixed on semiaxis, described planet pin and planet carrier are rotationally connected, described planetary pinion is meshed with planet pin Joint and with sun gear and gear ring, described planet carrier and wheel hub Joint, described wheel hub is rotationally connected by thrust bearing and spline housing, described float grease seal is arranged between wheel hub inner side and spline housing, described end cap and planet carrier Joint, described end cap, planet carrier, wheel hub and float grease seal surround a Seal cage jointly, therefore this transmission device is closed-type cylindrical gearing, float grease seal can prevent that lubricant oil from bleeding in break.
On technique scheme basis, the backing pin of restriction semiaxis dextrad play is installed on the right side of described end cap.
On technique scheme basis, on described end cap, detachable connection has plug screw, be can be used to charging-up lubricant oil and is controlled fuel head by the spiro pluging hole of plug screw shutoff.
On technique scheme basis, on described brake drum, be embedded with dust-proof cover.
On technique scheme basis, on the inner side surface of described brake drum, be processed with annular groove, these grooves can blocking part top layer crackle freely extend, the distortion of rising of the heat that can resist bulging body, keep the intrinsic shape of the condition of high temperature, groove is that heat extraction passage has been set up in the center portion of drum body, and groove can overcome skidding that oil, water-soaked causes, prevention brake failure in addition.
The utlity model has following advantage: tractive force is large, total reduction speed ratio is large, adopts planetary gear type drive mechanism compactness, and overall dimensions is less, is not easy oil leakage of closed-type cylindrical gearing, long service life.
