Description

Lubrication apparatus of speed changer
Technical field
The utility model relates to a kind of technology in automotive transmission field, specifically a kind of lubrication apparatus of speed changer.
Background technique
Automotive transmission generally includes the parts such as gear, synchronizer, bearing, oil sealing, these parts are in the process of running at high speed In can generate friction, local accumulation amount of heat influences function and the service life of part.Therefore, speed changer internal lubrication is well right Play the role of in the performance performance of speed changer highly important.Since speed changer internal structure is complicated, some components are due to knot Structure limitation is easy the presence of lubrication blind area, oil can not be got rid of by gear and carries out splashing lubrication, influences transmission duty performance.
Utility model content
The utility model In view of the above shortcomings of the prior art, proposes a kind of lubrication apparatus of speed changer, by turning It is provided with Oil Guide wheel on the jackshaft of dynamic state, oil liquid is driven to get rid of the bearing from the output end to speed changer and oil sealing of, is axis It holds and provides lubricating oil with oil sealing, while oil circulation is carried out by the oil circuit on shell, guarantee lubricating quality.
The utility model is achieved through the following technical solutions:
The utility model includes: the jackshaft being set in transmission case body and the Oil Guide wheel being fixed on jackshaft, Wherein: oil guide plate is equipped in transmission case body.
The jackshaft is achieved a fixed connection with Oil Guide wheel by locking nut, the Internal and external cycle of the locking nut respectively with Jackshaft and Oil Guide wheel interference fit.
The circlip for the limit of Oil Guide wheel is further provided on the jackshaft.
The oil guide plate is that a pair is horizontally placed on the reinforcing plate structure that output shaft two sides are corresponded in transmission case body.
It is corresponded in the transmission case body and is respectively equipped with oil-feed tank and out oil groove, oil-feed tank above and below oil guide plate Beginning and the terminal of oil groove is located at the getting rid of in oily range of Oil Guide wheel out, the beginning of the terminal of oil-feed tank and out oil groove is located at output The tip of the axis.
The Oil Guide wheel is ring-like impeller structure, and the leaf position of Oil Guide wheel is equipped with oil liquid through-hole, in which: oil liquid through-hole Direction and jackshaft it is axial consistent.
Corresponding output the tip of the axis is equipped with oil sealing on the case of transmission.
Technical effect
Compared with prior art, the utility model drives oil by being provided with Oil Guide wheel on the jackshaft of rotary state Liquid gets rid of the bearing and oil sealing of the output end to the inside of speed changer, provides lubricating oil for bearing and oil sealing, while by shell Oil circuit carry out oil circulation, realize comprehensive lubrication, improve lubricating quality, ensure that service life and the speed changer of part The efficiency of work.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model;
Fig. 2 is oil guide plate structural schematic diagram;
Fig. 3 is the utility model section schematic diagram;
Fig. 4 is the utility model stereoscopic schematic diagram;
Fig. 5 is Oil Guide wheel construction schematic diagram;
In figure: case of transmission 1, oil sealing 3, Oil Guide wheel 4, locking nut 5, jackshaft 6, oil guide plate 7, goes out oil groove at bearing 2 8, circlip 9, oil-feed tank 10, oil liquid through-hole 11, blade 12.
Specific embodiment
As shown in Figure 1, a kind of lubrication apparatus of speed changer being related to for the present embodiment, comprising: be set in case of transmission 1 Jackshaft 6 and the Oil Guide wheel 4 that is fixed on jackshaft 6, in which: oil guide plate 7 is equipped in case of transmission 1.
The jackshaft 6 is achieved a fixed connection with Oil Guide wheel 4 by locking nut 5, the Internal and external cycle point of the locking nut 5 It is not interference fitted with jackshaft 6 and Oil Guide wheel 4.
The circlip 9 limited for Oil Guide wheel 4 is further provided on the jackshaft 6.
The oil guide plate 7 is that a pair is horizontally placed on the reinforcing plate structure that output shaft two sides are corresponded in case of transmission 1.
It is corresponded in the case of transmission 1 and is respectively equipped with oil-feed tank 10 and out oil groove 8 above and below oil guide plate 7, The beginning of oil-feed tank 10 and the out terminal of oil groove 8 are located at the getting rid of in oily range of Oil Guide wheel 4, the terminal of oil-feed tank 10 and out oil groove 8 Beginning be located at output the tip of the axis.
As shown in figure 5,4 extension of Oil Guide wheel is equipped with blade 12, corresponding blade 12 is equipped with oil liquid through-hole 11, the oil The direction of fluid through-hole 11 is axial consistent with jackshaft 6.
Corresponding output the tip of the axis is equipped with oil sealing 3 on the case of transmission 1.
When speed changer operates, using the jackshaft for being in rotary state, Oil Guide wheel itself is driven persistently to rotate so that oil liquid Get rid of the oil guide plate on shell, oil liquid flows to oil-feed tank along oil guide plate, oil-feed tank by oil liquid be oriented to bearing in speed changer and Oil sealing provides lubricating oil for bearing and oil sealing;Fuel-displaced slot position is below bearing and oil sealing, and lubricated oil liquid is along oil groove out It flows back into inside speed changer in lower oil sump, realizes oil circulation.
Above-mentioned specific implementation can by those skilled in the art under the premise of without departing substantially from the utility model principle and objective with Different modes carries out local directed complete set to it, and the protection scope of the utility model is subject to claims and not by above-mentioned specific Implementation is limited, and each implementation within its scope is by the constraint of the utility model.
