Abstract
The utility model provides a non-forced lubrication gear for an engine. In the gear, the end face of the gear(1) is evenly provided with at least two arc lubricating oil channels(2) along the circumferential direction, and the lubricating oil channels(2) have inner ends communicated with a shaft hole(3) and outer ends connected with tooth faces(4); in the lubricating oil channels(2), arc directions from inner ends to outer ends are the same as the turning direction of the gear(1); the bottom faces of the lubricating oil channels(2) are provided with steps(5) on positions close to the outer ends; for the steps(5), outer sides are higher than inner sides. The non-forced lubrication gear realizes the reliable and complete lubrication between tooth faces and between the gear and a working face of the gear shaft by only adopting the splash lubrication mode, moreover, the non-forced lubrication gear also facilitates the normal performance of the engine.
Description
Technical field
The utility model relates to gear, relates in particular to the lubricating structure of gear in the motor.
Background technique
At present, the driving gear lubricating system of motor has pressure lubrication and optional lubricated two kinds, pressure lubrication is to be provided with on gear shaft axially and radial direction oil, and machine oil enters oil duct on the gear shaft by oil pump, and then enters the surface of contact between gear and the gear shaft; Optional lubricating then is to utilize the machine oil that splashes that the flank of tooth is lubricated.Because the on-stream machine oil that splashes is difficult to enter the surface of contact between gear and the gear shaft, so it is lubricated generally to need to adopt simultaneously pressure lubrication and optional lubricated dual mode to come realizing between the motor driving gear flank of tooth and gear and the axle.For simplifying the structure of gear shaft and casing oil leab, in the practical application, also often realize the immersion of operative minor between driving gear and the transmission shaft lubricated by the oil level that increases in the engine housing, promptly cancel the oil duct on the gear shaft, allow gear shaft partly immerse in the machine oil, though solved gear and axle lubrication problem like this, but because the machine oil face increases, the also corresponding increase of the running resistance of gear shaft, and machine oil temperature can be very high under the gear and the high speed of axle are stirred, thereby influence the normal performance of engine performance.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of non-forced lubrication gear for engine reliable, sufficient lubrication of realizing between gear and the gear shaft working surface.
For addressing the above problem, the non-forced lubrication gear for engine that the utility model provides, on the end face of gear, be and circumferentially be evenly equipped with at least two camber line shape oil leabs, the inner end of oil leab is communicated with axis hole, the outer end and the flank of tooth join, and the arc trend of oil leab from the inner end to the outer end is identical with turning to of gear.
Oil leab on the utility model middle gear end face not only can play and gather and the splash effect of machine oil of water conservancy diversion, and can also enter that the machine oil liquid level is following has ladled out machine oil that also drainage is to the gear axis hole, machine oil enters between gear and the gear shaft working surface again and realizes sufficient lubrication.After adopting said structure, not be used in oil duct is set on the gear shaft, also oil leab needn't be set on casing, gear shaft is partly immersed in the machine oil, simplified designs such as gear, axle and casing.This structure can reduce the lubricated of filling, and the machine oil liquid level is descended, gear, and the running resistance of axle reduces, and also is not easy to occur too high by the strong agitation temperature because of machine oil, influences the bring into normal play phenomenon of performance of motor.
The technique effect that the utility model is obtained is: employing splash lubrication mode just can realize reliable, the sufficient lubrication between the flank of tooth and gear and the gear shaft working surface, and helps the normal performance of engine performance.
Description of drawings
Fig. 1 is a perspective view of the present utility model, also is embodiment 1 structural representation.
Fig. 2 is embodiment 2 a structural representation.
Fig. 3 is the schematic representation of the utility model when being used as one grade of gear of engine countershaft.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, a kind of non-forced lubrication gear for engine of the present utility model, be on the end face of gear 1, to be circumferentially to be evenly equipped with at least two camber line shape oil leabs 2, the inner end of oil leab 2 is communicated with axis hole 3, the outer end and the flank of tooth 4 join, and the arc trend of oil leab 2 from the inner end to the outer end is identical with turning to of gear 1.Oil leab 2 not only can play and gather and the water conservancy diversion effect of machine oil of splashing, and can also enter that the machine oil liquid level is following has ladled out machine oil that also drainage is to the gear axis hole, and machine oil enters between gear and the gear shaft working surface again and realizes sufficient lubrication.After adopting said structure, not be used in oil duct is set on the gear shaft, also need not make gear shaft partly immerse in the machine oil, simplified gear shaft structure, because the machine oil liquid level descends, the running resistance of gear shaft reduces, and also is not easy to occur to influence because of oil temperature is too high the bring into normal play phenomenon of performance of motor.
The number of oil leab 2 should be set arbitrarily according to gear size and satisfying under the condition of working strength, and embodiment 1 shown in Figure 1 is circumferentially uniform 3 oil leabs 2 on gear 1 end face; 2 of embodiments shown in Figure 2 are circumferentially uniform 6 oil leabs 2 on gear 1 end face.
Can find out from Fig. 1, Fig. 2, the bottom surface of oil leab 2 is being formed with step 5 near the place, outer end, the outside of step 5 is higher than the inboard, can make the machine oil that enters oil leab 2 be not easy not throw away in the operation process with gear like this, guarantees to enter the oil level of gear axis hole.
In actual applications, as long as rigging position or drive connection allow, the gear that has can be provided with oil leab on two end face, to improve its lubrication effect.But the gear that has then only needs on an end face oil leab to be set to get final product, as one grade of gear on the engine countershaft, referring to shown in Figure 3, label 6,7,8,9,10 is respectively intermediate gear, three-range transmission, fourth gear, countershaft and the main shaft of motor among Fig. 3.
