Description

The Timing Belt case

Affiliated technical field

The utility model relates to the transmission device of motor car engine, and especially the accessory of Timing Belt transmission device belongs to automobile mechanical accessory manufacturing technology field.

Background technique

At present, the Timing Belt transmission device in the motor car engine comprises assemblies such as Idle wheel, Timing Belt and belt pulley, water pump gear and driving gear, owing to need sealing and dustproof and prevent that foreign matter from entering, is contained in usually in the Timing Belt case.Traditional Timing Belt case is to be that steel plate about 1mm is shaped through multiple tracks stretching, stamping processes by thickness, and manufacturing process is many and complicated, and the mould of Tou Ruing, frock, anchor clamps are various thus, and manufacturing and cost of material are all higher; And weight is heavier, can not ignore the influence of complete vehicle weight.

The model utility content

In order to overcome existing Timing Belt case cost height, the deficiency of manufacturing process complexity, it is a kind of to mould the Timing Belt case of Dai Gang, disposable injection molded that the utility model provides.

The technological scheme that its technical problem that solves the utility model adopts is: the Timing Belt case, to form by front end-cover 1 and rear casing 2, and front end-cover 1 comprises front end-cover panel 1.1, front end-cover shirt rim 1.2, front end-cover attachment hole 1.4; Rear casing 2 comprises rear casing panel 2.1, rear casing shirt rim 2.2, rear casing attachment hole 2.4 and rear casing mounting hole 2.7; Be equipped with reinforced block 1.3,2.3 on the forward and backward case shirt rim 1.2,2.2.

The case material adopts engineering plastics, and thickness is 2-3mm, and injection molded of case is established reinforced block on forward and backward case shirt rim, be according to product structure and material behavior, increases the structural strength of product with this.The front and back case is respectively established reinforced block 12-20, distributes along the shirt rim.

The beneficial effects of the utility model are, manufacture cost and the cost of material is low, operation is few, technology is simple, forming period is short, the manufacturing efficiency height, for the 6-10 of original efficient doubly; Product weight is light, is the 1/6-1/5 of conventional steel plates case only, has alleviated the weight of car load, has reduced oil consumption thus; The engineering plastics case also has certain decrease of noise functions, and material is recyclable, helps environmental protection.Product can be able to be worked under the ambient temperature more than 150 ℃ for a long time, and at high temperature indeformable, can satisfy the assembly and use requirements of vehicle well.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1-11, the Timing Belt case is made up of front end-cover 1 and rear casing 2, and front end-cover 1 comprises front end-cover panel 1.1, front end-cover shirt rim 1.2, front end-cover attachment hole 1.4; Rear casing 2 comprises rear casing panel 2.1, rear casing shirt rim 2.2, rear casing attachment hole 2.4 and rear casing mounting hole 2.7; Be equipped with 16 reinforced blockes 1.3,2.3 on the forward and backward case shirt rim 1.2,2.2.

The case material adopts engineering plastics Reinforced Nylon 6, injection molded of forward and backward case, and according to product structure and material behavior, the thickness of forward and backward

case

1,2 is 2mm, the thickness of shirt rim 1.2,2.2 is 3mm.As Fig. 2,5,7,11, the outer surface of inside and outside case panel 1.1,2.1 is the leather patterns face, can increase feel, prevents landing, and is convenient for assembly.

As Fig. 1,3,5, front end-cover panel 1.1 is provided with two width directions and is trapezoidal stiffening rib 1.5, to improve the structural strength of product.

As Fig. 6-11, attachment hole 2.4 places of rear casing outer surface are injection molded into nut sleeve 2.5, rear casing attachment hole 2.4 be provided with the metal threaded inserts 2.6 of Hexagon, rear casing mounting hole 2.7 places are provided with mounting hole packing ring 2.8, to reduce the assembly process of subsequent components, increase work efficiency thus.

In conjunction with the accompanying drawings embodiment of the present utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that carry out in the utility model scope all do not exceed protection domain of the present utility model.
