Abstract
The utility model relates to a double lubricating device for single-cylinder air-cooled diesel engine which comprises a gear box and an oil thrower disc which is mounted on a crankshaft; wherein a machine oil pump which is driven by a transmission mechanism is provided in the gear box, the oil inlet of the machine oil pump is communicated with the machine oil chamber which is at the bottom of the gear box, and the oil discharge channel is communicated the oil chamber of the oil thrower disc. The utility model changes the existing lubricating mode of simply depending on the operational gear in the gear box to bring oil to the oil thrower disc for splash lubrication in the single-cylinder air-cooled diesel engine to the double lubricating mode of force supplying oil to the oil thrower disc by the oil pump. When the machine oil is not enough and the lubricating fed by the prior art is not sufficient or not at all, the utility model can maintain a rather long period of sufficient lubricating, so as to effectively ensure the normal operation of the single-cylinder air-cooled diesel engine, to reduce the probability of failure in the machine, and even to reduce an appropriate quantity of weight of the machine and the pollution caused by the exhaust gas of the diesel engine.
Description
Affiliated technical field
The utility model relates to a kind of architecture advances of single-cylinder air-cooled diesel engine, is specifically related to the architecture advances of single-cylinder air-cooled diesel engine lubrication system.
Background technique
The lubrication system of present single-cylinder air-cooled diesel engine all is to adopt splash system lubrication, i.e. fixedly connected disc on the bent axle of single-cylinder air-cooled diesel engine, rely on the gear in the gear-box that the machine oil in the machine oil chamber is taken on the disc, utilize the centrifugal force on the disc that machine oil is thrown to and need be lubricated at lubricated position.When the machine oil in machine oil chamber is not enough, lubricated insufficient or not lubricated, diesel engine will break down, when use for diesel engine during in the mobile operational process machine coordination, carry guest machine oil pole inconvenience, or when burn oil appears in diesel engine, such accident is usually hard to guard against, both influenced production, and returned the economic loss that the user brings the maintenance facility, even have an accident.
Summary of the invention
In order to overcome the existing above-mentioned technical deficiency of single-cylinder air-cooled diesel engine, the utility model provides a kind of single-cylinder air-cooled diesel engine dual lubrication device, this device is when originally only relying in the gear slave oil pocket that turns round in the gear-box band oil to disc, also increase and force together to disc fuel feeding lubricating structure, as long as in the machine oil chamber a spot of machine oil is arranged, just lubricate and can not interrupt.
The technological scheme that the utility model technical solution problem is adopted is: comprise gear-box and the disc that is fixed on the bent axle, the oil pump that links to each other with driving mechanism is arranged in gear-box, machine oil chamber in the oil input channel of oil pump and the gear-box is connected, and the oil pump oil road communicates with the disc oil pocket.
Driving mechanism is starting gear and the Oil pump drive gear engagement on the starting shaft, drives oil pump work.
Oil road is sealed mutually to be communicated with and is formed by the oil outlet of the oil pump oil duct and the oil duct of gear box casing (diesel engine industry claims body) on gear box cover, and the outlet of oil road communicates with the disc oil pocket.
Organic oil warning device on oil road.
So just, formed the dual lubrication system, the gear in gear-box can be with in the disc on the machine oil band in the machine oil chamber, and it is lubricated that oil pump forces to form two fuel feeding to the disc fuel feeding; When the machine oil in the machine oil chamber is not enough, rely on gear band oil insufficient lubrication to occur or when lubricated, oil pump pressure fuel feeding also can keep providing in considerable time sufficient oil lubricating to disc to disc; Machine oil in the machine oil chamber seldom, (already showed machine oil deficiency on the machine oil calibrated scale this moment when oil pump oil pumping was not enough, early machine oil should have been annotated, this situation seldom takes place) the engine oil caution device that is provided with in the very noticeable place of oil pump oil road sinks because of the oil road underpressure, the timely alert operator filling machine oil that stops immediately.Thereby stop deadlock accident because of the insufficient lubrication generation.
The beneficial effects of the utility model are: bad or when not working in original splash system lubrication system works, when as long as the machine oil pasta is not less than the oil pump filler opening in the machine oil chamber of gear-box, oil pump just can be lubricated to the disc fuel feeding, guaranteed the proper functioning of single-cylinder air-cooled diesel engine effectively; Machine oil in the gear-box can also suitably reduce, and reduces the weight of diesel engine; The probability of diesel engine burn oil phenomenon also can reduce at random, alleviates the pollution of the waste gas of diesel emission to environment.

Specific embodiment
The utility model is a kind of single-cylinder air-cooled diesel engine dual lubrication device, comprise gear-box (2) and be fixed on disc (7) on the bent axle (8), the gear that the lubricating fitting of present single-cylinder air-cooled diesel engine is exactly running through gear-box (2) in brings to disc (7) with the machine oil in the machine oil chamber of gear-box (2) bottom, and utilizing centrifugal force in disc (7) running that machine oil is splashed to needs the position that lubricate and lubricate.Not enough as machine oil, then can insufficient lubrication or not lubricated, cause the kinematic pair in the diesel engine to burn out or burn to death.The utility model is equipped with the oil pump (5) that drives through driving mechanism in gear-box (2), the interior machine oil chamber of the oil input channel of oil pump (5) and gear-box (2) communicates, and the oil road (9) of oil pump (5) communicates with the oil pocket of disc (7).It is in the oil pocket of the machine oil that certain pressure is arranged that the oil road (9) of oil pump (5) the flows out disc (7) that can directly arrive running that what is called communicates.Disc (7) is splashed to machine oil at the position that needs lubricant oil together with bent axle (8) high speed rotating.As long as the machine oil face in the machine oil chamber of gear-box (2) bottom exceeds oil pump (5) oil input channel road junction, during the machine oil wretched insufficiency, lubricate and also can not end, so just constituted middle gear fuel feeding that turns round of disc (7) dependence gear-box (2) and oil pump (5) pressure dual lubrication device to disc (7) fuel feeding.Thereby guaranteed that all runnings are secondary lubricated fully.The mode of driving mechanism the best of oil pump (5) is the starting gear (3) and Oil pump drive gear (4) engagement on the starting shaft, driving machine oil pump (5) work.Oil road (9) can independently be provided with, best embodiment is, the oil duct that the oil outlet of oil pump (5) and gear box cover (1) are provided with, the oil duct three that gear box casing (diesel engine industry also claims body) is provided with seal and are communicated with formation, the oil outlet of oil road (9) communicates with the oil pocket of disc (7), emphasize again in passing that so-called the connection is not connection on the mechanism member, but can be directly injected to the oil pocket of disc (7) from the machine oil that certain pressure is arranged that the oil outlet of oil road (9) flows out.The most showy place of oil road (9) in oil pump (5) is provided with warning device (6), and when oil pump (5) proper functioning, the machine oil in the oil road (9) has certain pressure, engine oil caution device come-up; When oil pump (5) was inhaled less than the machine oil in the machine oil chamber, gear-box (2) bottom, the pressure in the oil road (9) was eliminated, and the engine oil caution device sinks, and filling machine oil is shut down in caution at once.
