Abstract

The utility model relates to a single-oil-duct chain idle wheel assembly which is characterized by comprising a chain idle wheel, a chain idle wheel bushing, a chain idle wheel shaft, a chain idle wheel thrust sleeve and a chain idle wheel bolt, wherein after being pressed into the chain idle wheel, the chain idle wheel bushing and the chain idle wheel are sheathed on the chain idle wheel shaft together; then, the chain idle wheel thrust sleeve is arranged at the rear end of the chain idle wheel shaft; and finally, the chain idle wheel thrust sleeve is fixed on a cylinder body by the chain idle wheel bolt. The single-oil-duct chain idle wheel assembly has the characteristics of simple and compact structure, easy manufacture, convenient assembly and disassembly, low cost, high reliability and the like.

Description

Single oil duct chain idle pulley assembly
Technical field
The utility model belongs to the technical field of engine chain transmission, particularly single oil duct chain idle pulley assembly.
Background technique
At present, the application of chain transmission on vehicular engine more and more widely.According to the needs of engine chain layout and realization motor velocity ratio, the application of chain idle pulley is also more and more.For the chain idle pulley of turriform, because the stressed difference of two-layer chain, idler shaft and chain idle pulley and thrust surface contact position are easy to occur wearing and tearing.Be the reliability of assurance chain transmission and the durability of complete machine, people also have higher requirement to the design of chain idle pulley.
Summary of the invention
The utility model purpose provides a kind of single oil duct chain idle pulley assembly.
The technical solution of the utility model is achieved in that
Single oil duct chain idle pulley assembly, it is characterized by: it is made up of chain idle pulley, chain idler bushing, chain idler shaft, chain idle pulley thrust housing and chain bolt of idler gear, after the chain idler bushing is pressed into the chain idle pulley, be enclosed within together on the chain idler shaft, then chain idle pulley thrust housing is contained in chain idler shaft rear end, is fixed on the cylinder body by the chain bolt of idler gear at last.
The utlity model has simple and compact for structure, easy to manufacture, easy accessibility, cost is low, characteristics such as reliability height.

Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Single oil duct chain idle pulley assembly, it is characterized by: it is made up of chain idle pulley 3, chain idler bushing 4, chain idler shaft 2, chain idle pulley thrust housing 5 and chain bolt of idler gear 1, after chain idler bushing 4 is pressed into chain idle pulley 3, be enclosed within together on the chain idler shaft 2, then chain idle pulley thrust housing 5 is contained in the rear end of chain idler shaft 2, is fixed on the cylinder body by chain bolt of idler gear 1 at last.
The thrust surface of the thrust surface of chain idler shaft 2 and chain idle pulley thrust housing 4 all is processed with radially spreader groove, is processed with lubricated oilhole on the idler shaft 2.
Embodiment:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model list oil duct chain idle pulley assembly, it is made up of chain idle pulley 3, chain idler bushing 4, chain idler shaft 2, chain idle pulley thrust housing 5 and chain bolt of idler gear 1, after chain idler bushing 4 is pressed into chain idle pulley 3, be enclosed within together on the chain idler shaft 2, then chain idle pulley thrust housing 5 is contained in the rear end of chain idler shaft 2, is fixed on the cylinder body by chain bolt of idler gear 1 at last.
Chain idler shaft 2 leaves certain radial and axial gap for chain idle pulley 3 when design, and after the installation of chain idle pulley assembly, chain idle pulley 3 can freely rotate on chain idler shaft 2 and axial float among a small circle; On chain idler shaft 2, also be processed with an oilhole 7, assembling back oilhole 7 is in the center of chain idler bushing 4, machine oil is in bolt hole enters chain idler shaft oilhole 7, and is lubricated to chain idler shaft 2 by the radial clearance infiltration of chain idler shaft 2 and chain idle pulley 3; On the thrust surface of the thrust surface of chain idler shaft 2 and chain idle pulley thrust housing 5, all be processed with radially spreader groove 6, wear and tear when preventing that chain idle pulley 3 from contacting with thrust surface.
The design of the lubricating oil path of the utility model chain idle pulley assembly is as follows: be processed with the tapped hole of a band heavy stand at the corresponding chain idle pulley of cylinder body assembly installed position, the oil duct of machine oil on cylinder body enters in the heavy stand of tapped hole.After the installation of chain idle pulley assembly, chain idle pulley thrust housing 5 is sealed the heavy stand end face, the gap of machine oil between chain bolt of idler gear 1 and chain idler shaft bolt hole enters in the chain idler shaft 2, enter between chain idler shaft 2 and the chain idler bushing 4 through the oilhole 7 on the chain idler shaft then, realization is lubricated to chain idler shaft 2, has guaranteed the reliability that chain idle pulley 3 rotates; Part machine oil can flow out by the matching gap between chain idler bushing 4 and the chain idler shaft 2 when oil pressure is higher, the machine oil that a part flows out can be stored in the spreader groove 6 of the thrust surface of chain idler shaft 2 and chain idle pulley thrust housing 4 thrust surfaces, prevent to occur when chain idle pulley 3 and thrust surface from fitting wearing and tearing, another part machine oil can flow on the chain along chain idle pulley 3, and chain is played lubrication assistant.
