Description
Technical field
The utility model relates to a kind of internal combustion engine part, especially relates to a kind of pitman arm shaft axle head jam anti-drop device.
Background technique
Internal-combustion engine belongs to a kind of dynamic power machine of burning fossil fuel, from prior art, internal-combustion engine can be divided into petrol engine and diesel engine, petrol engine and the common feature of diesel engine need fuel oil injected gas in-cylinder combustion, gas expansion thus produce thrust and promote the motion of cylinder piston, this straight reciprocating motion is converted to rotary motion and exports by piston again, in fuel oil in the cylinder combustion process, need the fuel oil straying quatity in control cylinder, the injection amount of air and the discharge capacity of waste gas, the control of above-mentioned amount needs to be achieved effective control of cylinder gate.And internal-combustion engine rocking arm belongs to the major way controlling valve, and internal-combustion engine rocking arm is mainly divided into intake rocker and exhaust rocker arm, due to the miniaturization of internal-combustion engine, on internal-combustion engine, the space of mounting parts is more and more less, once part comes off, not only be difficult to maintenance, and can this province of combustion motor damage.
Model utility content
The purpose of this utility model is to provide a kind of pitman arm shaft axle head jam anti-drop device, and efficiently solve the problem that pitman arm shaft axle head jam comes off, the technological scheme of employing is as follows:
Pitman arm shaft axle head jam anti-drop device, comprise pitman arm shaft, described pitman arm shaft comprises fixed idler whell, motion roller and adjusting bolt, described fixed idler whell and regulating wheel bolt are located at the two ends of pitman arm shaft respectively, be connected with cam in the axle sleeve that described motion roller is located at the stage casing of pitman arm shaft, described axle sleeve outer end is provided with a plurality of exterior bayonet slot, described motion roller is hollow structure, described hollow structure two ends are provided with a plurality of inner card cage, the outer projection of described exterior bayonet slot two ends and jam outer holds, described jam axle center place is also flexibly connected a cylindrical voussoir by bearing, described voussoir outer wall is provided with a plurality of interior projection, described interior projection holds mutually with inner card cage.
Further, described hollow structure inside is full of lubricant oil.
Further, described outer projection and exterior bayonet slot are interference fit.
Further, described fixed idler whell and pitman arm shaft are connected by outer bearing.
After adopting this structure, effectively can solve the problem that pitman arm shaft axle head jam comes off, maintain easily, and the inner charging-up lubricant oil of jam, be conducive to the working life extending part.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of pitman arm shaft axle head jam anti-drop device.
Embodiment
Pitman arm shaft axle head jam anti-drop device as shown in Figure 1, comprise pitman arm shaft 1, described pitman arm shaft 1 comprises fixed idler whell 4, motion roller 3 and adjusting bolt 5, described fixed idler whell 4 and regulating wheel bolt 5 are located at the two ends of pitman arm shaft 1 respectively, fixed idler whell 4 and pitman arm shaft 1 are connected by outer bearing 6, be connected with cam in the axle sleeve 2 that described motion roller 3 is located at the stage casing of pitman arm shaft 1, described axle sleeve 2 outer end is provided with a plurality of exterior bayonet slot 13, described motion roller 3 is hollow structure, hollow structure inside is full of lubricant oil, described hollow structure two ends are provided with a plurality of inner card cage 10, the outer projection 12 of described exterior bayonet slot 13 two ends and jam 8 outer holds, outer projection 12 is interference fit with exterior bayonet slot 13, described jam 8 axle center place is also flexibly connected a cylindrical voussoir 9 by bearing, described voussoir 9 outer wall is provided with a plurality of interior projection 11, described interior projection 11 holds mutually with inner card cage 10.
The above, be only embodiment of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in model utility.
