Abstract
The utility model discloses rocker arm combination for a gas distributing mechanism of an engine. The utility model comprises rocker arms, rocker arm shafts and a rocker arm supporting seat, wherein the rocker arm supporting seat (5) forms a U shape, the bottom end of the rocker arm supporting seat is provided with an installing hole (8), and both ends of the rocker arm supporting seat are symmetrically provided with shaft holes (9); one rocker arm shaft (3) is supported on the shaft holes (9) on both of the two ends of the rocker arm supporting seat (5), and two rocker arms (4) are in clearance fit with the rocker arm shafts (3) side by side. The utility model has the characteristics of stable operation, simple structure and small volume, the utility model is not easy to damage and the utility model can be solely replaced. The utility model is suitable for the gas distributing mechanism of a gasoline engine with the discharge under 50 CC.
Description
Technical field
The utility model relates to a kind of rocking arm combination of engine valve actuating mechanism, and particularly a kind of discharge capacity is the rocking arm combination of the following petrol engine underlying cammingly distribution device of 50CC.
Background technique
Discharge capacity is that the following petrol engine of 50CC is little owing to its volume, and its relevant component also must be thereupon little.At present, discharge capacity is that the rocking arm set of the following petrol engine distribution device of 50CC is combined into the needs that satisfy small volume, normally adopt the combination of upright post type rocking arm, its rocking arm adopts sheet metal impact briquetting; rocking arm by the flat borehole jack that is provided with on column; the circular arc bottom of rocking arm is limited in the post shoulder of column, and is that the guide pin bushing and the nut of sphere locks with the lower end, realizes shaking by this circular arc.But this rocking arm combination is owing to rely on arc track to shake, and it is stable inadequately to work under strenuous exercise, and the valve clearance easily changes, and influences engine operation, and noise increases, and needs often to regulate the valve clearance; And make because of it adopts sheet metal, easily form collision deformation or fracture, influence engine operation.Discharge capacity is that the rocking arm of the following petrol engine distribution device of 50CC also has the forging adopted to make, but adopt the distribution device of this rocking arm to be generally overhead-cam, it increases the volume of cylinder head, and camshaft and rocking arm shaft support all are the aluminum alloy material with the casting of cylinder head one, easy to wear under the friction of camshaft and pitman arm shaft, its wearing clearance will cause the variation of valve clearance slightly greatly, influence engine operation, noise increases, in this case, have only the replacing engine cylinder head, increase user's maintenance cost.
Summary of the invention
The purpose of this utility model provides a kind of rocking arm combination of engine valve actuating mechanism, and it has characteristics not fragile, working stability, and can change separately.
The purpose of this utility model is achieved in that and comprises rocking arm, pitman arm shaft, rocker arm support, it is characterized in that: described rocker arm support is made as " Qian " shape, its bottom is provided with mounting hole, its two ends are symmetrical arranged axis hole, a pitman arm shaft is supported in the axis hole at rocker arm support two ends, on the pitman arm shaft side by side Spielpassung two rocking arms are arranged.
Be with lining on the described pitman arm shaft between two rocking arms.
The threaded one end that described rocking arm contacts with valve is combined with a valve adjustments screw, and locks with the valve adjustments nut, and the end that rocking arm contacts with push rod is provided with the sphere depression.
Owing to adopted such scheme, two rocking arms arranged side by side are installed on " Qian " shape rocker arm support by pitman arm shaft, " Qian " shape rocker arm support is installed on the cylinder head with screw is fastening by mounting hole, rocking arm was shaken around axle, working stability, prolonged the working life of rocking arm combination, and it is extremely convenient that the damage of rocking arm combination simultaneously back is changed, and needn't change cylinder head.Be with lining on the described pitman arm shaft between two rocking arms, what lining produced in the time of reducing two rocking arm alternating motions arranged side by side influences each other, and makes the more stable work of rocking arm.The threaded one end that described rocking arm contacts with valve is combined with a valve adjustments screw, and with the locking of valve adjustments nut, makes the adjusting of valve clearance easy, and the valve clearance keeps better; The end that rocking arm contacts with push rod is provided with sphere depression, helps cooperating of push rod and rocking arm.
The utility model is simple in structure, and volume is little, is applicable to that discharge capacity is the following petrol engine distribution device of 50CC.
The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment
Referring to Fig. 1 to Fig. 5, the rocker arm support 5 of this rocking arm combination is made as " Qian " shape, and its bottom is provided with two mounting holes 8, and its two ends are symmetrical arranged axis hole 9.A pitman arm shaft 3 is supported in the axis hole 9 at rocker arm support 5 two ends, axis hole 9 Spielpassung of pitman arm shaft 3 and rocker arm support 5, and pitman arm shaft 3 stretches out 5 ones of rocker arm supports with back-up ring 7 axially locating.On the described pitman arm shaft 3 side by side Spielpassung two Rocker arm 4s are arranged, be with lining 6 on the pitman arm shaft 3 between two Rocker arm 4s.The threaded one end that described Rocker arm 4 contacts with valve is combined with a valve adjustments screw 2, and locks with valve adjustments nut 1, and the end that Rocker arm 4 contacts with push rod is provided with the sphere depression.
Referring to Fig. 6, rocker arm support 5 usefulness the screws 11 of this rocking arm combination are fastened on the cylinder head 13; the valve adjustments screw 2 on the pitman arm shaft 3 on two Rocker arm 4s arranged side by side respectively with the corresponding valve that is in open mode 12 contacts, the sphere on two Rocker arm 4s caves in respectively and corresponding push rod 10 contact matching.Lower arranging cam axle rotates, and promotes two Rocker arm 4s respectively by two push rods 10 and shakes around pitman arm shaft 3, drives pairing valve 12 work.It is fashionable to need to change this rocking arm set, turns on screw 11, just can take off the rocking arm combination and change, and makes the user can save maintenance expenses.
