Abstract
The utility model discloses a mounting structure of a timing chain wheel, a signal wheel and a camshaft in an engine. The mounting structure comprises the signal wheel (1), the timing chain wheel (3) and the camshaft (5), wherein the signal wheel (1) and the timing chain wheel (3) are fixedly connected to a camshaft fixed plate (4) via bolts (2), wherein the camshaft fixed plate is in the front end of the camshaft (5). According to the above technical schemes, the mounting structure of the timing chain wheel, the signal wheel and the camshaft in the engine provided in the utility model is simple-structured and easy-assembling, wherein all components are mounted in the front end of the camshaft, so that the engine is more compact, thereby being helpful for installation and maintenance of functional members on the camshaft, saving the amount of the components, and guaranteeing circumferential positioning of the signal wheel and the timing chain wheel upon the camshaft.
Description
Technical field
The utility model belongs to engine art, and more specifically, the utility model relates to a kind of engine timing sprocket wheel, signal wheel and camshaft mounting structure.
Background technique
Timing sprocket is fixed on the camshaft front end on the conventional engines, the signal wheel is fixed in the middle of the camshaft or the rear end; The structural design of fixed convex wheel shaft was in camshaft axle body or rear end when assembled correct time; Because the space is bigger; These parts can not interfered with other part when camshaft rotated, and this design takes to be placed on the bearing support can only assemble based on camshaft the time, covered cylinder cap or bearing cap again.When if engine design is not compact, when perhaps the camshaft dismounting must draw and insert-type, and the each several part structure designs separately, makes component more, if the partial function spare on the camshaft damages, assembling and maintenance are also inconvenient.
The model utility content
The utility model problem to be solved is to the deficiency of existing technology, a kind of assembling and engine timing sprocket wheel, signal wheel and camshaft mounting structure easy to maintenance to be provided.
To achieve these goals, the technological scheme taked of the utility model is:
This engine timing sprocket wheel that the utility model provided, signal wheel and camshaft mounting structure comprise signal wheel, timing sprocket and camshaft, and described signal wheel and timing sprocket are connected on the camshaft fixed tray of camshaft front end through bolt.
On described camshaft fixed tray, be provided with pin-and-hole.
Described camshaft passes through locating stud that pin-and-hole is fixedly connected on cylinder body or the cylinder cap on the camshaft fixed tray.
Adopt technique scheme, this engine timing sprocket wheel that the utility model provided, signal wheel and camshaft mounting structure, simple in structure; Be easy to assembling; All component are installed in the camshaft front end, make motor more compact, help the installation and the maintenance of functor on the camshaft; Saved amount of parts, also guaranteed that signal is taken turns and timing sprocket is circumferentially located simultaneously on camshaft.
Description of drawings
The mark of facing down among expressed content of each width of cloth accompanying drawing of this specification and the figure is made brief description:
Fig. 1 is the STRUCTURE DECOMPOSITION schematic representation of the utility model;
Fig. 2 is signal wheel and a timing sprocket erection drawing in the utility model.
Be labeled as among the figure:
1, signal wheel, 2, bolt, 3, timing sprocket, 4, the camshaft fixed tray, 5, camshaft.
Embodiment
Extremely shown in Figure 2 like Fig. 1; This engine timing sprocket wheel that the utility model provided, signal wheel and camshaft mounting structure; Comprise signal wheel 1, timing sprocket 3 and camshaft 5, signal wheel 1 is fixedly connected on the camshaft fixed tray 4 of camshaft 5 front ends through bolt 2 with timing sprocket 3.
Adopt technique scheme, this engine timing sprocket wheel, signal wheel and camshaft mounting structure, simple in structure; On camshaft fixed tray 4, process three tapped holes; Signal wheel 1 is fixed on the camshaft fixed tray 4 through bolt 2 with timing sprocket 3, and all component all design at camshaft 5 front ends, make the motor overall structure more compact; The functor that also helps on the camshaft 5 is installed and maintenance; Bolt 2 is passed the hole on signal wheel 1 and the timing sprocket 3, saved amount of parts like this, reduced cost.
To shown in Figure 2, on camshaft fixed tray 4, be provided with pin-and-hole like Fig. 1.
Camshaft 5 passes through locating stud that pin-and-hole is fixedly connected on cylinder body or the cylinder cap on the camshaft fixed tray 4.
Adopt technique scheme, camshaft 5 to pass through locating stud that pin-and-hole is fixedly connected on cylinder body or the cylinder cap on the camshaft fixed tray 4, the phase angle when having guaranteed camshaft 5 assemblings like this.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
Claims (3)
1. an engine timing sprocket wheel, signal are taken turns and the camshaft mounting structure; Comprise signal wheel (1), timing sprocket (3) and camshaft (5), it is characterized in that: described signal wheel (1) and timing sprocket (3) are fixedly connected on the camshaft fixed tray (4) of camshaft (5) front end through bolt (2).
2. according to the described engine timing sprocket wheel of claim 1, signal wheel and camshaft mounting structure, it is characterized in that: on described camshaft fixed tray (4), be provided with pin-and-hole.
