Abstract
The utility model discloses a starting main shaft for a motorcycle engine, which includes a starting main shaft body (1), wherein an oil passage (2) communicated with the starting main shaft body (1) is arranged inside the starting main shaft body (1); a cooper sleeve (3) is arranged on the starting main shaft body (1); one or more oil holes (4) communicated with the oil passage (2) are arranged at the part of the starting main shaft body (1), corresponding to the inner wall of the cooper sleeve (3); a spiral oil passage (5) is arranged on the inner wall of the cooper sleeve (3). The starting main shaft has the advantages of ingenious structural design, simple technology and high reliability, can be used for excluding impurities inside the cooper sleeve, improves the lubricating effect, and enhances the abrasive resistance, and besides, prolongs the service lives of the main shaft and the auxiliary shaft.
Description
Technical field
The utility model relates to a kind of motorcycle engine, and particularly a kind of motorcycle engine starts main shaft.
Background technique
At present, motorcycle engine in use finds, there will be and starts the fault that the copper sheathing on axle is worn, and by trouble analysis, finds, and motor is when running up, and the impurity in machine oil can enter in copper sheathing and can't get rid of, and causes copper sheathing to wear and tear.Because this copper sheathing belongs to oily nest type copper sheathing, oily nest type copper sheathing belongs to oily nest oil storage, and impurity can be accumulated wherein, can't discharge, and easily produce burr during oily nest type copper sheathing machining, thereby produce the copper sheathing inordinate wear, causes motor to damage.
The model utility content
The purpose of this utility model just is to provide a kind of motor that starts the eliminating of the impurity in copper sheathing on axle that can make and admits that motor is with starting main shaft.
The purpose of this utility model is to realize by such technological scheme, a kind of motorcycle engine is with starting main shaft, comprise and start the main shaft body, be provided with in starting the main shaft body and connect the oil duct that starts the main shaft body, be provided with copper sheathing on startup main shaft body, starting on the main shaft body and being provided with copper sheathing inwall corresponding part the oilhole that at least one is communicated with oil duct, be provided with the spirality oil duct on the inwall of described copper sheathing.
Wherein, described oilhole is corresponding with the middle part of copper sheathing inwall.
In order to get rid of more impurity, described oilhole is two, and corresponding with the both sides of copper sheathing inwall respectively.
More smooth and easy for despumation, be provided with oil groove at the filler opening place of described oilhole.
Owing to having adopted technique scheme, the utlity model has the advantage that structural design is ingenious, technique is simple, reliability is high, adopt it the impurity in copper sheathing can be got rid of, promoted lubrication effect, strengthen wear resistance, simultaneously, also extended the working life of major-minor axle.
The accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is the first structural representation of the present utility model;
Fig. 2 is copper sheathing structural representation of the present utility model;
Fig. 3 is the third structural representation of the present utility model;
Fig. 4 is the 4th kind of structural representation of the present utility model;
Fig. 5 is the 5th kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement on the present embodiment essence spirit or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, a kind of motorcycle engine is with starting main shaft, comprise and start main shaft body 1, be provided with in starting main shaft body 1 and connect the oil duct 2 that starts main shaft body 1, be provided with copper sheathing 3 on startup main shaft body 1, starting on main shaft body 1 and being provided with copper sheathing 3 inwall corresponding parts the oilhole 4 that at least one is communicated with oil duct 2, be provided with spirality oil duct 5 on the inwall of described copper sheathing 3, described oilhole 4 is corresponding with the middle part of copper sheathing 3 inwalls.
The utility model is work like this: start in main shaft body 1 high speed rotating process and produce centrifugal force, the impurity in copper sheathing 3 is discharged by oilhole 4, so just eliminated the wearing and tearing of impurity to copper sheathing 3.Simultaneously, at the spirality oil duct 5 of copper sheathing 3 inwall settings, make lubricant oil be flowed interior, make copper sheathing 3 obtain lubricated, improved lubrication effect.
Embodiment 2: as shown in Figure 3, described oilhole 4 is two, and corresponding with the both sides of copper sheathing 3 inwalls respectively, and more thorough that two oilhole can get rid of impurity is set.
Claims (4)
1. a motorcycle engine is with starting main shaft, comprise and start main shaft body (1), be provided with in starting main shaft body (1) and connect the oil duct (2) that starts main shaft body (1), be provided with copper sheathing (3) on startup main shaft body (1), it is characterized in that: starting main shaft body (1) above and being provided with copper sheathing (3) inwall corresponding part the oilhole (4) that at least one is communicated with oil duct (2), be provided with spirality oil duct (5) on the inwall of described copper sheathing (3).
2. motorcycle engine as claimed in claim 1 is with starting main shaft, and it is characterized in that: described oilhole (4) is corresponding with the middle part of copper sheathing (3) inwall.
