Abstract
The utility model discloses a side placed type valve device for a universal gasoline engine. The utility model comprises a cylinder body, wherein an intake valve and an exhaust valve are arranged on the cylinder body. A valve spring which causes a valve to downwards close a valve hole is arranged on the intake valve and the exhaust valve, and the valve spring is supported between a valve spring seat of the valve and a cylinder body wall. A tappet is pushed by a cam, fine threads are processed on the upper section of the tappet and a regulating nut and a locking nut are arranged on the upper section of the tappet. When the tappet runs upwards, spring force is overcome and the valve is pushed aside by the regulating nut. The utility model has the advantages that the threads, the locking nut and the regulating nut are processed on the upper section of the tappet, the tappet is matched with the valve through the regulating nut, the regulating nut can regulate height on the tappet, the regulating nut is locked by the locking nut after gaps are appropriate, and the structure is simple; after the proposal is used, complicated grouping and replacing procedures can be omitted, the utility model with low cost can enhance the maintainability of the gasoline engine and the reliability of the gasoline engine is raised.
Description
Technical field
The utility model relates to the adjustment of engine valve clearance, in particular for the valve clearance controlling mechanism of side-mounted general gasoline engines.
Background technique
The general gasoline engines of the side-mounted valve of prior art, require employing under the very simple prerequisite at engine structure often, so that save cost as far as possible, reduce sales price, its valve mechanism is also simplified as far as possible, shown in accompanying drawing 1, pushes tappet 2 by cam 1, make tappet 2 directly promote valve 6, make valve up; Spring retainer 3 is stuck on the valve 6 and compresses valve spring 5, valve spring 5 one ends are pressed on the cotter seat 3, and the other end is pressed on the cylinder block 4, when tappet 2 is descending when leaving valve 6, the restoring force of valve spring 5 makes valve descending, thereby reaches the purpose of unlatching, closed valve.Because the characteristic of side-mounted valve, tappet directly cooperates with valve, and in order to reduce cost, these 2 parts all adopt the solid forging part, valve clearance is difficult to adjust, present way is, with valve and tappet after machine shaping, measure, be divided into a lot of groups according to tolerance range, in assembling, if the valve clearance is undesirable, then change assembly and close, change, cause efficiency of assembling low and change to organize just valve, valve spring, cotter seat, tappet all to be pulled down to reach the valve clearance of regulation; And, when petrol engine is worked a period of time in user's hand, after cam and tappet produce wearing and tearing, just can't adjust, directly influenced the power of petrol engine, for this reason, though the method for prior art adjustment valve clearance is very many, but these methods are not too suitable mostly for side-mounted general gasoline engines.
The model utility content
The purpose of this utility model is: a kind of valve gear of side-mounted general gasoline engines is provided, solves the problem of above-mentioned adjustment valve clearance, under prerequisite easy to use, structure is very simple, so that cost of production is low.
In order to achieve the above object, the valve gear of side-mounted general gasoline engines of the present utility model, comprise cylinder block, establish the inlet and outlet door on the cylinder block, be equipped with on the inlet and outlet door and make valve downwards and close the valve spring of valve port, valve spring is supported between the gentle cylinder wall of laterostigmatal Spring retainer, tappet is promoted by cam, the tappet epimere is processed with fine thread, and adjusting nut and locking nut are installed in the tappet epimere, overcomes spring force by the adjusting nut unseat the valve when tappet is up.
The utility model has the advantages that: by processing fine thread at the tappet epimere, add a locking nut and adjusting nut, tappet does not directly cooperate with valve, and should cooperate with valve by adjusting nut, adjusting nut can be at tappet adjusted height, after the gap is suitable, adjusting nut is locked with locking nut, structure is very simple, after using this scheme, can save loaded down with trivial details grouping and change program, the cost of production that changing structure increases is lower than the cost that grouping is changed, and has improved the maintainability of petrol engine, and the reliability of petrol engine is got a promotion.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of valve gear of the side-mounted general gasoline engines of prior art.
Fig. 2 is the structural representation with the valve gear of side-mounted general gasoline engines of the present utility model.
Embodiment
Referring to accompanying drawing 2, the valve gear of side-mounted general gasoline engines of the present utility model, comprise cylinder block 4, establish on the cylinder block 4, exhaust valve 6, advance, be equipped with on the exhaust valve 6 and make valve downwards and close the valve spring 5 of valve port, valve spring 5 is supported between the Spring retainer 3 gentle cylinder walls on the valve 6, tappet 2 is promoted by cam 1, tappet 2 epimeres are processed with fine thread, fine thread is accurate and help regulating, adjusting nut 8 and locking nut 7 be according to the epimere that is installed in tappet 2 up and down, overcomes spring force by adjusting nut 8 unseat the valves 6 when tappet 2 is up, installs or when using, adjusting nut 8 can rotate on tappet 2 regulates height, after the gap is suitable, adjusting nut 8 is locked, do not need valve with locking nut 7, valve spring, cotter seat, tappet is all pulled down and is changed, and efficiency of assembling improves.
Claims (1)
1. the valve gear of a side-mounted general gasoline engines, comprise cylinder block (4), cylinder block is established on (4), exhaust valve (6), advance, be equipped with on the exhaust valve (6) and make valve downwards and close the valve spring (5) of valve port, valve spring (5) is supported between the gentle cylinder wall of Spring retainer (3) on the valve (6), tappet (2) is promoted by cam (1), it is characterized in that: described tappet (2) epimere is processed with fine thread, adjusting nut (8) and locking nut (7) are installed in tappet (2) epimere, overcome spring force by adjusting nut (8) unseat the valve (6) when tappet (2) is up.
