Abstract
A single cylinder diesel transmission gear set forced lubrication structure comprises a long shaft diameter, a crank journal, a short shaft diameter, a timing gear shaft diameter, an oil inlet channel, a crank oil cavity, an oil outlet channel, a slide bearing, a crank timing gear, a spiral oil tank and an oil outlet. The oil outlet hole and the spiral oil tank are arranged at the matched section of the short shaft diameter and the slide bearing, one end of the spiral oil tank is communicated with the oil outlet, and the other end of the spiral oil tank faces a meshed face of the crank timing gear. Lubrication oil pumped by a machine oil pump can be directly sprayed on a tooth face of the crank timing gear through the oil inlet channel, the crank oil cavity, the oil outlet channel, the oil outlet and the spiral oil groove. The crank timing gear is a driving gear for driving a diesel transmission gear set. The lubrication oil sprayed from the spiral oil tank can be transmitted to other transmission gears through the crank timing gear, so that the diesel transmission gear set can be effectively lubricated. Furthermore, the lubrication conditions between the short shaft diameter and the slide bearing can be further improved. The technical scheme doesn't increase cost and is economical and practical.
Description
Technical field:
The utility model relates to a kind of single cylinder diesel, relates in particular to the gear lubricating structure of single cylinder diesel.
Background technique:
In single cylinder diesel, all gears drive by crankshaft timing gear in the driving gear set, at the bent axle brachycephaly crankshaft timing gear is housed, during the diesel engine normal operation, the lubricated of driving gear set is to lubricate by the mist of oil that the lubricant oil in the crank-shaft link neck of single-cylinder diesel engine lubrication system forms when crankshaft high-speed rotates, by the resuscitation apparatus on the gear chamber cover mist of oil is sucked in the gear chamber, thereby driving gear set is lubricated, this lubricating system oil mass is few, reliability is very low, diesel engine is when work, because the poor lubrication of driving gear set, gear tooth noise is very large, and friction velocity is fast between gear, cause the machine temperature higher, the working life of driving gear set is short.This is the common fault of single cylinder diesel, in order to overcome this defective, someone adopts from lubricant pump is upper outside and draws a high-pressure unit oil pipe and be connected on the gear chamber cover, with the oil outlet tube hydraulic fluid port to living driving gear set, although this scheme implementation can be dealt with problems, but the difficulty of implementing is larger, not only to increase external high-pressure oil pipe, also to carry out Drilling operation to gear chamber cover, the cost of every machine will increase more than 10 yuan, and the not all type of this improvement project can both implement, and the claimant has carried out conscientious research and analysis by the lubrication system to existing diesel, found the lubricated scheme of a kind of effective solution diesel engine driving gear set.
The model utility content:
The purpose of this utility model provides a kind of forced lubrication structure for transmission gear set of single-cylinder diesel engine, adopt such lubricating structure, the lubricated oil that loses can not appear in driving gear set, can reduce gear tooth noise and machine temperature, can improve again wear resistance and the working life of driving gear set, do not increase cost yet, economical and practical.
A kind of forced lubrication structure for transmission gear set of single-cylinder diesel engine, it is characterized in that: it comprises the major axis footpath, crankshaft journal, short shaft diameter, the timing gear diameter of axle, oil inlet passage, the bent axle oil pocket, oil discharge passage, sliding bearing, crankshaft timing gear, helical oil groove and oil outlet, one end and the bent axle oil pocket of oil discharge passage interlink, oil discharge passage forms oilhole on the surface of short shaft diameter, oil outlet is positioned at the sliding bearing fitting surface, helical oil groove is arranged on the section of cooperation of short shaft diameter and sliding bearing, one end of helical oil groove communicates with oil outlet, and the other end of helical oil groove is to living the Surface of action of crankshaft timing gear.
Further, the pitch of described helical oil groove more than or equal to the oil outlet center of oil discharge passage to the distance between the short shaft diameter exterior edge face.
The lubricant oil that oil pump is extracted out is by in the oil inlet passage input bent axle oil pocket, lubricant oil is input to the surface of short shaft diameter from oil outlet by oil discharge passage, because helical oil groove is opened on the outer surface of short shaft diameter, and interlink with the oil outlet of oil discharge passage, lubricant oil can be directly injected on the flank of tooth of crankshaft timing gear from helical oil groove, because crankshaft timing gear is the driving gear that drives the diesel engine driving gear set, begin to lubricate from crankshaft timing gear and speed regulation gear engagement place from the lubricant oil of helical oil groove ejection, pass to again other driving gear, like this can not only be effectively the driving gear set of diesel engine be lubricated, and can further improve lubricating condition between short shaft diameter and the sliding bearing, can also improve camshaft, starting shaft, the lubricating condition of all the lining cooperation places on the speed governing axle, this scheme does not need to increase any part, only when the turning short shaft diameter in passing car go out a helical oil groove and get final product, can not increase cost, not only economy but also practicality, prove through claimant's repetition test, adopt this lubricating structure, can further reduce the engagement driving noise of diesel engine, start light, the machine temperature decreases, and be improved the working life of driving gear set.
