Abstract

The utility model provides a lubricating gear driving mechanism, comprising a drive shaft 3, a gear wheel 2 which is movably sheathed with the shaft and a gear ring 1 on one side of the gear wheel 2. The utility model is characterized in that a spiral oil groove 4 is arranged on position which matches with the gear wheel 2 of the drive shaft 3; the rotary direction of the spiral oil grooves 4 and the gear wheel 2 are same when the spiral oil grooves 4 and the gear wheel 2 rotate around the shaft. An oil-entering channel 5 is arranged on the oil-entering end facing of the gear wheel 2. The gear ring 1 is inner clip type ring. The utility model is in particular used for the main shaft of the motorcycle engine and the mechanical driving of the reverse gear; the mating part between the driving gear wheel and the main shaft is sufficiently lubricated and cooled; the favorable mechanical driving is kept; the durability of each part is lengthened; the installation of the designed gear ring is simple and quick. The preventing falling effect is good.

Description

A kind of oilgear driving mechanism

Technical field:

The utility model relates to a kind of mechanical transmission, especially a kind of a kind of oilgear driving mechanism that is applicable to motorcycle engine.

Background technique:

In mechanical transmission, lubricated is the important performance indexes that guarantees the normal transmission of mechanical parts.At present the lubricated of motorcycle engine inside is to be infused in the engine housing by lubricant oil, by the rotation of driving gear lubricating oil splash realized at workpiece surface.This lubricated can only being lubricated to gear surface, and the matching part between gear and the axle is become lubricated dead angle.Because this matching part can not get sufficient lubrication, so when high-speed gear rotate, can produce sharp-pointed howling, can cause the local superheating scaling loss in the time of seriously, make sky be enclosed within the smooth switching that reverse gear on the main shaft can't be realized reverse gear and forward gears.

The content of model utility:

The purpose of this utility model provides a kind of lubricant oil that can make through the mating part between gear and the axle, make sky be enclosed within on the axle gear with spool mating part a kind of oilgear driving mechanism of obtaining lubricating.

The purpose of this utility model is achieved in that a kind of oilgear driving mechanism of design, comprise transmission shaft and kink gear on this and the ring washer that is positioned at gear one side, its key points in design is: A. with the transmission shaft of gear matched section on be processed with helical oil groove, this helical oil groove is identical with the rotation direction that gear sways; B. the oil-feed end face at gear is processed with oil input channel, and the described ring washer of C. is an inner blocking type annulus ring washer.

Helical oil groove on the described transmission shaft is the right hand helix oil duct, and it is 4mm that its spiral oil duct is designed to pitch, and groove width is 1mm, and groove depth is 0.5mm, is useful on the motorcycle reverse gear engine spindle.

The oil input channel of described gear oil-feed end face is three straight troughs.

Described ring washer is circular, and the inner ring of its annulus has one section to be straight line.

Adopt the advantage of such scheme to be: the mating part between gear and the transmission shaft can obtain sufficient lubrication, cooling, helps to keep the favorable mechanical transmission, prolongs the working life of each part; It is simple, quick that designed ring washer is installed, and Drop-proof is effective.

Below in conjunction with drawings and Examples the utility model is further specified.

Description of drawings:

Fig. 1 is a plan view of the present utility model;

Fig. 2 is the sectional view of Fig. 1 middle gear 2;

Fig. 3 is the sectional view of ring washer 1 among Fig. 1.

Specific embodiment:

Please see Figure 1, Fig. 2, Fig. 3, this embodiment describes is mated condition between motorcycle reverse gear engine spindle and reverse gear.As shown in Figure 1, the utility model mainly is made up of ring washer 1, gear 2, transmission shaft 3, and its middle gear 2 kinks are at an end of transmission shaft 3, and a side of gear 2 is spacing by the step of transmission shaft, and opposite side is spacing by the ring washer 1 that is sleeved on the axle 3.The utility model is with the difference of prior art: A. with the transmission shaft 3 of gear 2 sections of cooperation on be processed with helical oil groove 4, this helical oil groove 4 is identical with the rotation direction that gear 2 sways; B. the oil-feed end face at gear 2 is processed with oil input channel 5, and the described ring washer 1 of C. is an inner blocking type annulus ring washer.

Helical oil groove 4 on the transmission shaft described in Fig. 13 is the right hand helix oil duct, and its pitch is 4mm, and groove width is 1mm, and groove depth is 0.5mm.

As shown in Figure 2: the oil input channel 5 of described gear 2 oil-feed end faces is three straight troughs, and its groove width is 2mm, and groove depth is 1mm.Three straight troughs are set, are convenient to gear and in rotation process, lubricant oil are constantly introduced in the helical oil groove 4.

As shown in Figure 3: ring washer 1 is circular, and the inner ring of its annulus has one section to be straight line.During installation, need be by other instrument, the straightway of annulus inner ring can prevent to come off.This ring washer not only has the dimension compensation effect, and has limit function, and it does not influence the unimpeded of lubricating oil path outlet.

Working principle: when motor is in the reverse gear gear, reverse gear 2 on the transmission shaft (being main shaft) 3 turns clockwise, lubricant oil is entered in the helical oil groove 4 of transmission shaft 3 by three oil input channels 5 on the reverse gear 2, because the sense of rotation of reverse gear 2 is corresponding with the rotation direction opening of helical oil groove 4, so, when gear 2 high speed rotating just as having increased pump oil power, the oil pocket that lubricant oil is flowed through rapidly under the help of this power and formed by spiral oil duct and gear hole inwall, partly carry out comprehensive lubricated to axle and gear matched, cooling, then, lubricant oil is flowed out by the other end.
