Abstract
The utility model provides a time correction system of an engine. According to the time correction of the engine, a crankshaft gear (1) is meshed with a main idle gear (2), the main idle gear (2) is meshed with high-pressure oil pump gear (3), a drive sprocket (4) is connected with the main idle gear (2) in a coaxial mode, and the drive sprocket (4) is connected with a camshaft sprocket (5) in a matched mode through a time correction chain (6). Due to the fact that a structure combining gear transmission and chain transmission is adopted, the combined transmission structure is capable of simultaneously having advantages of the gear transmission and the chain transmission, and defects of a single transmission structure are made up. The time correction system of engine is stale in transmission, light in structure, and high in working reliability.
Description
Technical field
The utility model relates to engine art, relates in particular to a kind of engine timing system.
Background technique
Gear transmission is the mechanical motion that utilizes the intermeshing transferring power of the gear teeth of two gears and motion.Gear transmission is steady, and velocity ratio is accurate.Reliable operation, efficiency is high, and the life-span is long, and the power of use, speed, dimensional range are larger.But gear transmission is inapplicable and long apart from transmission, and, for impacting engagement, the transmission of noise ratio chain is large.
The chain transmission is to belong to the engagement driving with middle flexible element, and it has gear transmission concurrently and with the Some features of transmission.With gear transmission, compare, chaindriven manufacture and installation precision require lower; The sprocket tooth stressing conditions is better, and bearing capacity is larger; Certain buffering and damping property are arranged; Centre distance can be greatly and structure is light.
At present, what the timing system of most of motors adopted is gear drive or chain drive, and drive form is single.Can not take into account the length of gear-driven reliable and chain apart from transmission and the light advantage of structure.
The model utility content
For the problems referred to above, the utility model provides a kind of engine timing system, adopts gear transmission to add chaindriven structure, and this Combined rotary structure can be taken into account the advantage of gear transmission and chain transmission simultaneously, stable drive, and structure is light, and functional reliability is high.
For realizing the purpose of this utility model, the utility model has adopted following technological scheme:
A kind of engine timing system, crankshaft gear and the engagement of main idle gear, main idle gear and high-pressure oil pump gear engagement, drive sprocket coaxially is connected with main idle gear, and drive sprocket and camshaft sprocket are connected by timing chain.
Alternatively, described drive sprocket is bolted on main idle gear.
Alternatively, described crankshaft gear and high-pressure oil pump gear are 25 teeth, and described main idle gear is 50 teeth.
Alternatively, described camshaft sprocket is 26 teeth, and the lazy sprocket wheel of described master is 26 teeth.
The utility model beneficial effect is:
The utility model adopts gear to add the combination kind of drive of sprocket wheel.Crankshaft gear, main idle gear and high-pressure oil pump gear mesh successively and form the tooth transmission.Gear transmission has the moment transmission, the high and structural stability of stability, and transmission power is large, the advantage that efficiency is high.Drive sprocket and camshaft sprocket are connected and form the chain transmission by timing chain.Chain rotates to have the application environmental requirement not bery highly, can be used for high temperature, heavy duty, low speed, environment that dust is larger, and is applicable to the advantage of distant two between centers transmissions.This combination kind of drive is taken into account the advantage of gear transmission and chain transmission, and has made up the deficiency of single transmission structure, stable drive, and structure is light, and functional reliability is high.
The accompanying drawing explanation
The engine timing system structural representation that Fig. 1 is the utility model embodiment.
Drive sprocket and main idle gear linkage structure schematic diagram in the engine timing system that Fig. 2 is the utility model embodiment.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
A lot of details have been set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can be in the situation that do similar popularization without prejudice to the utility model intension, so the utility model is not subject to the restriction of following public specific embodiment.
As shown in Figure 1, it is the structural representation of the timing system of a 2.7L CTI diesel engine, in this embodiment, crankshaft gear 1 and main idle gear 2 engagements, main idle gear 2 and high-pressure oil pump gear 3 engagements, drive sprocket 4 and camshaft sprocket 5 are connected by timing chain 6, and described drive sprocket 4 is fixed on main idle gear 2 by bolt 7, as shown in Figure 2, drive sprocket 4 is connected for axle with main idle gear 2.
In this embodiment, crankshaft gear 1 drives main idle gear 2, main idle gear 2 drives high-pressure service pump gear 3, the drive sprocket 4 coaxial with main idle gear 2 passes through chain drive camshaft sprocket 5, by the cooperation between gear and drive sprocket 4, with the axle of main idle gear 2, is connected, and realized gear and sprocket wheel compound mode, meet the transmission demand of different parts simultaneously, stable drive, structure is light, and functional reliability is high.
At one, more specifically in embodiment, described crankshaft gear 1 and high-pressure oil pump gear 3 are 25 teeth, and described main idle gear 2 is 50 teeth, camshaft sprocket 5 is 26 teeth, and described drive sprocket 2 is 26 teeth, thereby, the velocity ratio of bent axle and camshaft is 2, and the velocity ratio of bent axle and fuel pump is 1.Be only example herein, be understandable that, those skilled in the art can, according to concrete needs, arrange the number of teeth of gear to reach required velocity ratio.
Although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model.Any those of ordinary skill in the art, do not breaking away from technical solutions of the utility model scope situation, all can utilize method and the technology contents of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not break away from technical solutions of the utility model, do any simple modification, equivalent variations and modification according to technical spirit of the present utility model to above embodiment, all still belongs in the scope of technical solutions of the utility model protection.
