Description
Technical field
This utility model relates to technical field of transmission, particularly relates to a kind of Dual directional tightener.
Background technology
Tensioner is holding means conventional on belt, chain transmission system, is characterized in keeping belt, chain in transmission
During can have suitable tensile force, thus avoid belt creep, or avoid Timing Belt occur to jump tooth, de-tooth and haul out,
Or prevent chain-loose, come off, alleviate sprocket wheel, chain wear.
But the stretcher being applied to dynamo belt of prior art mainly include one fixing on the engine the
One fix seat, be rotatably connected on first and fix second on seat and fix seat, be arranged on the second tension assembly fixing on seat, rotation
The first regulating wheel of being connected on tension assembly and be rotatably connected on the second the second regulating wheel fixing on seat, because this
Tight device is two-way, i.e. tension assembly self can rotate tension adjusting, and tension assembly entirety can be along with second simultaneously
Fixing seat rotates tension adjusting, so causing tension assembly unitary rotation relatively big, again because of tension assembly unitary rotation angle
Degree is relatively big, and the damping piece of prior art is two pieces, and has bigger gap between two pieces of damping pieces, so works as tension assembly
Turn to during certain some angle, have the uneven phenomenon of damping force produce so that the tension effects of stretcher entirety is poor.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of preferable Dual directional tightener of tension effects.
This utility model be the technical scheme is that a kind of Dual directional tightener, including fixing on the engine first
Fixing seat, it is rotatably connected on first and fixes second on seat and fix seat, be arranged on the second tension assembly fixing on seat, the company of rotation
The first regulating wheel of being connected on tension assembly and be rotatably connected on the second the second regulating wheel fixing on seat, described tension assembly
Including
Base, is fixed on second and fixes on seat；
Turning arm, is rotatably connected on base, and is rotationally connected for the first regulating wheel；
Spring, between described base and turning arm, spring upper end end face contacts with turning arm, lower spring end end face with
Base contacts, is used for biasing described turning arm and makes it inside contract direction motion towards described spring；
Damping piece, circumference spacing on turning arm and and base contacts, for provide stop turning arm rotate friction resistance
Buddhist nun's power；
Bracing frame, is arranged between spring and damping piece and fixes with damping piece, is used for preventing from directly extruding resistance because of spring
Damping member and make damping piece damage；
Described damping piece is three pieces, and described three pieces of damping pieces are uniformly arranged on bracing frame, and three pieces of damping pieces are installed to
A complete circle is formed after on bracing frame.
Using above structure compared with prior art, this utility model has the advantage that two pieces of original damping pieces
Change three pieces of damping pieces into, and three pieces of damping pieces are installed on support member one complete circle of rear formation, such damping piece and damping
Just not having bigger space between part, no matter so tension assembly rotational angle is much, the damping force that it is provided all compares all
Even, and then make the tension effects of Dual directional tightener preferable.
As preferably, described three pieces of damping pieces are all detachably connected on bracing frame.Installation maintenance side is so set
Just.
As preferably, described damping piece is the circular arc with spacing preiection, and support frame as described above is the circle of band stopper slot,
Described spacing preiection matches with stopper slot, and described damping piece place diameter of a circle is less than the straight of support frame as described above place circle
Footpath.So arranging, damping piece dismounting is more convenient, and the ratio that can block between damping piece and bracing frame is stronger.
As preferably, described first fixes seat is provided with annular protrusion, and described second fixes seat is provided with and annular protrusion
The through hole matched, described annular protrusion stretches into and is additionally provided with lining between through hole, and the outer wall of described annular protrusion and the inwall of through hole
Set, and described first fix seat and second and fix and be additionally provided with pad between seat.First fixes seat and second fixes and adopts between seat
Using this rotational structure, rotating effect is preferable, and because being provided with lining, and also it is provided with pad, rub the most between the two
Wiping power is less, and then makes tension assembly can preferably go to regulate the second regulating wheel.
