The plane of layer fits closely, and the protective layer is fitted in the glass cotton rope layer surface, and the canvas layer includes fitting in rubber
The embryo cloth layer and wear-resistant coating coated on the embryo cloth layer surface of the layer flank of tooth.
Preferably, the embryo cloth layer is woven by nylon wire and aramid line.
Preferably, the wear-resistant coating uses polytetrafluoroethylene (PTFE).
Preferably, the glass cord ply includes described in the glass cotton rope main body as made of glass wire coiling and fixation
The colloid of glass cotton rope main body.
Preferably, the rubber layer uses hydrogenated nitrile-butadiene rubber.
Compared with prior art, a kind of Timing Belt not needing stretcher of the utility model, for driving engine
The attachmentes such as water pump, lubricating oil pump and vacuum pump, including：Protective layer, glass cord ply, rubber layer and canvas layer, wherein the rubber
Glue-line is wedge structure, and the side of the rubber layer of the wedge structure is plane, and the other side is the flank of tooth, the glass cord ply and institute
The plane for stating rubber layer fits closely, and the protective layer is fitted in the glass cotton rope layer surface, and the canvas layer includes fitting
In the embryo cloth layer of the rubber layer flank of tooth and wear-resistant coating coated on the embryo cloth layer surface.The utility model does not need stretcher
Formal belt, by be arranged wedge structure rubber layer, and the rubber layer surface of the wedge structure be arranged canvas layer so that
The belt tension decaying of the utility model is extremely low, can directly connect with driving wheel and driven wheel, without installing auto-tensioning dress
It sets and guide rail, so that the structure of drive system is more simple, greatly reduces friction loss, while improving transmission efficiency, drop
Low production cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the Timing Belt for not needing stretcher of the utility model.
As shown in the figure：1- protective layer, 2- glass cord ply, 3- rubber layer, 4- canvas layer.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.It should be noted that the utility model attached drawing is all made of simplified form
And non-accurate ratio is used, only to convenient, lucidly aid illustration the utility model embodiment purpose.
As shown in Figure 1, the utility model provides a kind of Timing Belt for not needing stretcher, for driving engine water
The attachmentes such as pump, lubricating oil pump and vacuum pump, including：Protective layer 1, glass cord ply 2, rubber layer 3 and canvas layer 4.Wherein, described
Rubber layer 3 is wedge structure, and the side of the rubber layer 3 of the wedge structure is plane, and the other side is the flank of tooth, the glass cord ply
2 are fitted closely with the plane of the rubber layer 3 by glue, and the protective layer 1 is then fitted tightly over the glass by glue
The surface of cord ply 2, the canvas layer 4 include fitting in the embryo cloth layer of 3 flank of tooth of rubber layer and coated on the embryo cloth layer surface
Wear-resistant coating.
Preferably, the embryo cloth layer is woven by nylon wire and aramid line, and fixed by dipping process.
Preferably, the wear-resistant coating uses polytetrafluoroethylene (PTFE), which is covered on described by attaching process
The surface of embryo cloth layer.Using the utility model the Timing Belt for not needing stretcher when, the wear-resistant coating is directly and driving wheel
Or driven wheel contact, it can protect the rubber layer 3 and be not worn, while the embryo cloth layer of the canvas layer 4 can also increase
The friction of 3 flank of tooth of rubber layer, avoid the Timing Belt for not needing stretcher using when have skidded.
Preferably, the glass cord ply 2 includes the glass cotton rope main body as made of glass wire coiling and fixed institute
The colloid of glass cotton rope main body is stated, specifically, the glass cotton rope main body is fixed by dipping process, in other words, the glue
