Abstract
The utility model discloses a lubrication device for timing camshafts of engines, which is characterized in that an oil hole (2) is arranged on an inclined surface of a timing sprocket positioning slot of a timing camshaft (1). The utility model has the advantages of assurance of lubrication of a driven sprocket and a chain, long service life of the engine and low operation noise.
Description
The utility model belongs to engine art, particularly a kind of lubricating fitting that is used for the engine timing camshaft.
At present, be used for the motor on the big discharge capacity motorcycle, adopt the timing chain transmission usually.Mainly rotation drives lubricant oil to chain greasisng to the chain greasisng of this method by sprocket wheel.Because timing drive sprocket and timing driven sprocket apart from each other, driven timing sprocket is seldom lubricated, and makes timing driven sprocket and chain almost in a kind of dry friction operation of unlubricated oil, causes motor noise in running big, and reduces the life-span.
The purpose of this utility model provides a kind of engine timing camshaft lubrication device, and it can guarantee the lubricated of driven sprocket and chain, the motor long service life, and noise is little when operation.
For reaching above-mentioned purpose, it is characterized in that having oilhole on the inclined-plane of the timing sprocket locating slot of timing camshaft.
The angle of the center line of oilhole and timing camshaft center line is 30～75 °.
The diameter of oilhole is 1.5～3.5mm.
Oilhole passage and tapped hole crosspoint are 7～15mm to the distance of timing sprocket locating face.
The utility model is because oilhole passage and tapped hole crosspoint are 7～15mm to the distance of timing sprocket locating face, so can guarantee that clamping bolt can not stop up oilhole after the timing driven sprocket is fixed with clamping bolt; Because the center line of oilhole and the angle of timing camshaft center line are 30～75 °, can utilize the rotary centrifugal force of engine oil pressure and timing camshaft that the lubricant oil in the camshaft is directly injected on timing follower and the chain is lubricated, therefore the utility model has the motor long service life, the little characteristics of noise in the running.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a structure diagram of the present utility model.
Referring to Fig. 1.Top on the inclined-plane of the timing sprocket locating slot of timing camshaft 1 has oilhole 2.The angle of the center line of oilhole 2 and timing camshaft 1 center line is 30～75 °, and oilhole 2 passages and tapped hole crosspoint are 7～15mm to the distance of timing sprocket locating face.The diameter of oilhole 2 is 1.5～3.5mm.
When engine operation, because the center line of oilhole and the angle of timing camshaft center line are 30～75 °, the diameter of oilhole 2 is 1.5～3.5mm, can utilize the rotary centrifugal force of engine oil pressure and timing camshaft that the lubricant oil in the camshaft is directly injected on timing follower and the chain and be lubricated.
Oilhole 2 passages and tapped hole crosspoint are 7～15mm to the distance of timing sprocket locating face, can guarantee that clamping bolt can not stop up oilhole after the timing driven sprocket is fixing with clamping bolt.
