Background technique
Traditional engine oil pump all is contained in the front end of engine cylinder-body, is directly driven by bent axle, and this driving mode causes the motor length overall longer, and the oil pump sealing is difficulty relatively.Therefore, the oil pump that is installed on the motor adopts chain and drives owing to the restriction that is subjected to the space, do like this have the efficient height, noise is low, vibration is little, precision is high, can bear and run up and high capacity, adopt chain transmission both to guarantee good quiet effect simultaneously, improve the Security of transmission system running, have non-maintaining characteristics again.But, because chain can produce wearing and tearing in use for some time, cause the length of chain to be elongated, thereby make chain vibration, climbing tooth occur, phenomenon such as come off, also can cause the loss of power simultaneously, the chain after being elongated can produce extra noise when rotating.
In the chain-driven process of oil pump, because oil pump running is steady relatively, do not require that chain drive system has damping function, only require chain is carried out to a certain degree tensioning.For this reason, people have proposed various solutions through long-term exploration, and some has also applied for patent.For example, Chinese patent discloses a kind of timing chain transmission and engine oil pump drive system [publication number is: CN 101363335A], it comprises the crankshaft sprocket that is double dentation, one row goes up the timing chain of walking around the inlet and outlet sprocket wheel is installed, another row go up to install the oil pump chain of walking around the oil pump sprocket wheel, the oil pump sprocket wheel be positioned at crankshaft sprocket under.
Though above-mentioned this structure helps the tensioning to chain, also there is deficiency on the each several part size of concrete structure, cause effectively reaching tensioning, the easy play of chain to the appropriate benefit of chain.And this timing chain transmission and engine oil pump drive system cost are higher.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, proposed a kind of simple in structure, processing cost is low, can effectively prevent the chain drive of the oil pump of chain releasing.
The purpose of this utility model can realize by following technical proposal:
The chain drive of this oil pump, be arranged in the cylinder body of oil pump, comprise driving sprocket wheel, sprocket wheel and chain, described driving sprocket wheel and sprocket wheel are in the same plane, described chain winding is on driving sprocket wheel and sprocket wheel, it is characterized in that this chain drive also comprises the stretcher that can prevent that chain is loosening, described stretcher is resisted against on the chain under the elastic force effect of elastic component.
In the chain drive of this oil pump, by stretcher prevent chain vibration, climbing tooth, come off, stretcher then is resisted against on the chain by the elastic force of elastic component, the purpose of She Zhiing is like this, and stretcher all is resisted against on the chain all the time.It is simple in structure, and is easy to process, and processing cost is low.
In the chain drive of above-mentioned oil pump, described stretcher comprises body, one side of described body is the butting section that leans with above-mentioned chain, described butting section is curved, also be provided with the bolt mounting holes post on described body, above-mentioned elastic component is arranged on the described bolt mounting holes post.
In the chain drive of above-mentioned oil pump, described elastic component is the torsion spring that is set on the above-mentioned bolt mounting holes post, the two ends of described torsion spring be resisted against respectively body and oil pump cylinder body on.
In the chain drive of this oil pump, adopt the elastic force of torsion spring that body is resisted against on the chain, and a side of body is curved, has better engagement with chain, the resistance that chain is subjected in transmission process is little, and is little to the wearing and tearing of chain.
In the chain drive of above-mentioned oil pump, offer mounting groove on the described body, an end of above-mentioned torsion spring is positioned at described mounting groove.
The purpose of She Zhiing is like this, and an end of torsion spring is fixed, and makes torsion spring more firm, in use can not occur rocking, and further reduces noise.
Compared with prior art, the chain drive of this oil pump has the following advantages: can make chain be in tensioning state constantly, prevent the generation of noise, the generation of phenomenon such as simultaneously also reduced vibration, climbing tooth, come off.
