Description
Technical field
The utility model relates to a kind of belt stress.
Background technology
Belt stress is used for the driving belt of tensioner automobile engine, belt is kept appropriate tensile force, avoids skin
Band skids, caused elongation after the abrasion of compensation belt, aging.Belt stress makes transmission skin by being tensioned swing arm and swinging back and forth
Band remains tensioner in operation process, and is tensioned the swing arm operation whether stable life-span for directly affecting belt stress and makes
With caused noise, the tensioning swing arm less stable of existing belt stress, vibration and noise, service life are also easy to produce
It is shorter.
The content of the invention
In view of technical problem existing for background technology, it is steady that the technical problems to be solved in the utility model is to provide a kind of operation
Fixed, service life length belt stress.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that to realize：This kind of belt
Tight device, includes belt pulley, tensioning swing arm, support base and mandrel, and the belt pulley is arranged on the right-hand member of tensioning swing arm, and belt
Bearing is provided between wheel and tensioning swing arm, the left end of the tensioning swing arm sets axis hole, plastic shaft is provided with the axis hole
Set, the mandrel are arranged in plastic sleeve, and one end of the tensioning swing arm left end is arranged with spring, and the support base is arranged on
Tensioning swing arm is provided with the end face of spring, and the support base is connected with mandrel, and the other end of the tensioning swing arm is provided with
Riveting pad assembly, it is characterised in that the riveting pad assembly includes riveting pad and plastics damping sheet, and the riveting pad has installation cavity, described
Riveting pad is arc-shaped concave towards the end face of tensioning swing arm, and the other end of the riveting pad has a short slot, the two of the riveting pad
End face is communicated with installation cavity, and the plastics damping sheet is arranged in the installation cavity of riveting pad, assembling when, the riveting pad assembly with
Mandrel riveting is connected, and the plastics damping sheet is bonded with tensioning swing arm.
Plastic washer is provided between the tensioning swing arm and support base.
The end face of the belt pulley offers heat emission hole.
The riveting pad is made up of 65Mn steel.
Riveting pad of the present utility model is before assembly arc-shaped concave towards the end face of tensioning swing arm, and after assembling, riveting pad exists
Under mandrel riveted pressure, plastics damping sheet is bonded with being tensioned the end face of swing arm so that plastics damping sheet produces with tensioning swing arm end face
Raw active force, when so tensioning swing arm swings back and forth, plastics damping sheet produces damping, and the riveting pad is made of 65Mn steel, ties
Arc-shaped concave is closed, riveting pad is flexible so that damping has subsequent compensation, and it is more steady in the operating condition to be so tensioned swing arm
It is fixed, abate the noise, service life is more permanent；Plastic washer between the support base and tensioning swing arm then eliminates tensioning swing arm
Worn during swing with support base, swing tensioning swing arm more steady, extend its service life.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is sectional view of the utility model along Figure 1A-A lines.
Embodiment
