Abstract
The utility model relates to the technical field of car engines and particularly relates to a car engine main bearing cover with a balanced shaft mounting hole. The car engine main bearing cover comprises a bearing cover body (1), wherein a lug boss (2) is arranged at the center of the top of the bearing cover body (1); the lug boss (2) is a cylindrical lug boss; the lug boss (2) is provided with a mounting hole (3) for mounting a balanced shaft; the mounting hole (3) is a threaded hole. Compared with the prior art, the car engine main bearing cover with the balanced shaft mounting hole is novel and simple in structure and reasonable in design; the problem in the prior art that the vibration of a car engine is large is solved and the shaking of the engine, caused by unbalanced operation, is relieved greatly, so that a bent axle can work at a stable state and the mechanical efficiency is improved; the car engine main bearing cover with the balanced shaft mounting hole is convenient to machine and easy to realize.
Description
[technical field]
The utility model relates to technical field of automobile engine, specifically a kind of Main Bearing Caps for Automobile Engines with trunnion shaft mounting hole.
[background technique]
Motor is the important motivity parts in automobile, for providing power to automobile.Motor, by transmitter bent axle outputting power, need to cover main bearing cap when mounted on bent axle.When motor is in working state, the movement velocity of piston is very fast, and speed is very inhomogeneous; When piston is positioned at upper and lower dead-centre position, its speed is zero, but reaches the highest in the speed in upper and lower stop neutral position.Because piston is done high-speed straight-line motion repeatedly in cylinder, therefore will inevitably on piston, wrist pin and connecting rod, produce larger inertial force, because these inertial force can not reach balance, motor now has just produced vibrations.Therefore, if can solve the problem that engine luggine is large, it is being worked more stably under state, will have very important significance.
[model utility content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of Main Bearing Caps for Automobile Engines with trunnion shaft mounting hole is provided, solved the large problem of engine vibration in prior art, realize maintenance bent axle working under state more stably, promoted mechanical efficiency.
Design for achieving the above object a kind of Main Bearing Caps for Automobile Engines with trunnion shaft mounting hole, comprise bearing cap body 1, described bearing cap body 1 center of top position is provided with a boss 2, and described boss 2 is provided with for the mounting hole 3 of trunnion shaft is installed.
Described mounting hole 3 is tapped hole.
Described boss 2 is cylindrical boss.
The utility model compared with the existing technology, novel structure, reasonable in design, because the center of top position at bearing cap body is cast with a columniform boss, and on this cylindrical boss, be processed with for the tapped hole of trunnion shaft is installed, thereby solved motor car engine in prior art, shake large problem, greatly alleviated because moving the uneven motor shake causing, realize maintenance bent axle working under state more stably, promoted mechanical efficiency; In addition, the Main Bearing Caps for Automobile Engines structure with trunnion shaft mounting hole described in the utility model is very simple, easy to process, is easy to realize, and by the change of main bearing cap, can get a desired effect, and is worthy of popularization.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural representation of Main Bearing Caps for Automobile Engines in prior art;
Fig. 4 is the plan view of Fig. 3;
In figure: 1, bearing cap body 2, boss 3, mounting hole.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is done to following further illustrating:
As shown in Figures 1 and 2, the utility model comprises: bearing cap body 1, and bearing cap body 1 center of top position is provided with a boss 2, and this boss 2 is cylindrical boss, and boss 2 is provided with for the mounting hole 3 of trunnion shaft is installed, and this mounting hole 3 is tapped hole.
As shown in accompanying drawing 3 and accompanying drawing 4, be the structural representation of Main Bearing Caps for Automobile Engines in prior art, its top only has a chain-wales, for mark product batch number etc.
The utility model is by the cylindrical boss of top casting at Main Bearing Caps for Automobile Engines, and on boss, be processed with for the tapped hole of trunnion shaft is installed, thereby can directly the flat transverse axis of bent axle be arranged in this main bearing cap, broken the original state that original trunnion shaft is arranged on cylinder body, make motor more succinctly light, the imbalance opposing of bent axle has been played to more direct, favourable effect.
In the utility model, processing is during engine main bearing cover, can be directly by hole processing out, process very conveniently, and be easy to realize.
The utility model is not subject to the restriction of above-mentioned mode of execution; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
