Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
Embodiment one
With reference to Fig. 2, the present invention provides a kind of mechanical tensioner 4, comprising: guide chain plate 41 and spring element 5.Wherein, it leads
Carrier bar 41 is equipped with spaced mounting portion 43 and chain contact boss 42；Chain contact boss 42 is used for and chain drive system
Chain 31 in system 3 offsets.Spring element 5 is installed, spring element 5 includes winder 51 and torque arm 52, volume on mounting portion 43
It is used to be sheathed on mounting portion 43 along axial direction around portion 51.
When mechanical tensioner 4 of the invention is applied on engine (not shown), with reference to Fig. 3, pacified using being contained in
Pin shaft 40 in 43 central through hole 44 of dress portion installs mechanical tensioner 4 to engine.Guide chain plate 41 can be rotated around pin shaft,
And the end of torque arm 52 is contacted with the external peripheral surface for the pin shaft 30 being fixedly arranged on engine, pin shaft 30 can prevent 52 turns of torque arm
It is dynamic.To which torque arm 52 and the pin shaft 30 of tensioning apparatus offset, the chain 31 in chain contact boss 42 and chain transmission system 3
It offsets, tensile force is provided by spring element 5, with tension chain 31.
Existing mechanical tensioner is not able to satisfy the requirement under different application scene to tensile force, machinery of the invention
Tight device can be adapted in the chain tension system for the requirement for having different to tensile force.
Specifically, the winder 51 of spring element 5 of the invention has Internal periphery, the outer peripheral surface of mounting portion 43 is circumferentially
The outer profile to match at least two with Internal periphery；After winder 51 is sheathed on mounting portion 43 along axial direction, winder 51
One outer profile of Internal periphery and mounting portion 43 fits so that winder 51 is circumferentially transported with fixed have no of mounting portion 43 relatively
It is dynamic.
Referring to figs. 2 and 3, when using mechanical tensioner 4 of the invention, winder 51 can be mounted on along axial direction and is led
On the mounting portion 43 of carrier bar 41, winder 51 and mounting portion 43 circumferentially fix after without relative motion, spring element 5 can provide
Corresponding tensile force in this state.
It, can be by the winder edge of spring element 5 if needing different tensile forces in other application scenarios lower chain
After circumferentially rotating set angle, then it is axially mounted on mounting portion 43.At this point, the Internal periphery of winder 51 and mounting portion 43
Other outer profiles fit so that winder 51 circumferentially with mounting portion 43 is fixed has no relative motion, spring element can be with
Corresponding tensile force in this state is provided.That is, mechanical tensioner 4 of the invention can be adapted for having tensile force
In the chain tension system of different requirements.
Meanwhile the end of torque arm 52 of the invention offsets with pin shaft 30, and winder 51 and mounting portion 43 circumferentially without
Relative motion, it is not necessary that spring element is fixed on mounting portion by two torque arm as prior art.Installation is simple, and meets
The performance requirement of tensile force is provided.
It should be noted that the distribution position of the outer profile to match on mounting portion 43 of the invention with the Internal periphery of winder 51
It sets corresponding with the angle that winder 51 rotates.Specifically, as wherein one on the Internal periphery and mounting portion 43 of winder 51
After a outer profile matches, winder 51 provides the first tensile force in this state.After winder 51 rotates set angle, volume
Match around the Internal periphery in portion 51 and other outer profiles on mounting portion 43, torque arm 52 offsets with pin shaft 30, in the state
Lower winder 51 provides the second tensile force.And so on, winder 51 rotate set angle so that the Internal periphery of winder 51 with
One outer profile of mounting portion 43 matches, and winder 51 provides corresponding tensile force.
In addition, with reference to Fig. 1, in the prior art, torsional spring 1 has the first torque arm 12 and the second torque arm 13, the first torque arm 12, the
Two torque arm 13 extend outwardly from the head end of winder 11, end along the tangential direction of winder 11 respectively；Pass through the first torque arm 12
Torsional spring 1 is installed on mounting post 22 with the second torque arm 13.But in the prior art, the first torque arm 12 and the second torque arm 13 exist high
It is poor to spend, and the first torque arm 12 and the second torque arm 13 undertake stress respectively, and the stress undertaken can generate not in same plane
The torque of Y-direction as shown in Figure 1.
This allows for the winder 11 of torsional spring 1 not only by the torque circumferentially (in Fig. 1 shown in X-direction), also by along Y
The torque in direction.The winder 11 of torsional spring 1 can be driven to overturn along the torque of Y-direction, so that winder 11 is installed on mounting post 22
It is upper unstable, tensile force cannot be steadily provided.
In order to solve the above technical problems, referring to figs. 2 and 3, the torque arm 52 and winder 51 of spring element 5 of the invention connect
It connects and in same plane.Wherein, winder 51 has head end and end, and winder 51 is in the shape of a spiral.The end of winder 51
Fixed with mounting portion 43, tangential direction of the torque arm 52 from head end along winder 51 extends outwardly.The head end of winder 51 is winding
The starting in portion 51 winds end, and the end of winder 51 is that winder 51 stops winding end.
It should be noted that torque arm 52 and winder 51 are in same plane it is to be understood that along axial direction, the upper table of torque arm 52
Face flushes completely with the upper surface of winder 51, alternatively, the upper surface of torque arm 52 and the upper surface of winder 51 slightly have height
It is poor to spend；The lower surface of torque arm 52 flushes completely with the lower surface of winder 51, alternatively, the lower surface of torque arm 52 and winder 51
Slightly there is difference in height in lower surface.
Only one torque arm 52 of spring element 5 of the invention, torque suffered by spring element 5 are in same plane；Together
When, the Internal periphery of the winder 51 of spring element 5 fits with an outer profile of mounting portion 43 and circumferentially mutually fixation has no
Relative motion, increases the stability that winder 51 is connect with mounting portion 43, and winder 51 can steadily provide tensile force.

Bayonet 47 that hook 511 is aligned on mounting portion 43 at the one end of mounting portion 43 far from guide chain plate 41 is simultaneously inserted into the bayonet 47, so
Winder 51 is sheathed on the outer peripheral surface of mounting portion 43 along axial direction afterwards, and hook 511 also moves in bayonet 47 along axial direction.Portion to be spooled
After 51 extremely fit with guide chain plate 41 axially movable, hook 511 and bayonet 47 are fixed.Winder 51 and mounting portion 43 are in circumferential direction
Circumferential limit is realized in the upper clamping by hook 511 and bayonet 47.
Hook 511 and one of bayonet 47 in winder 51 shown in Fig. 5 is fixed, in this state, winder 51
First tensile force is provided.If needing different tensile forces in other application scenarios lower chain, with reference to Fig. 5 and Fig. 6, will wind
After portion 21 circumferentially rotates set angle (in Fig. 5 shown in the direction T), then it is axially mounted on mounting portion 43；At this point, winder
Hook 511 on 51 is clamped with another 47 phase of bayonet, and winder 51 and mounting portion 43 are still circumferentially fixed and without opposite
Movement.
As shown in fig. 6, in this state, the torque arm 52 of spring element 5 and the position of winder 51 are changed, sending out
In the case that 30 position of pin shaft in motivation remains unchanged, after torque arm 52 offsets with pin shaft 30, tensioning provided by spring element 5
Power changes.So, can demand according to different application scene lower chain to tensile force, by the hook 511 in winder 51
It is inserted on mounting portion 43 in corresponding bayonet 47.Bayonet 47 on mounting portion 43 circumferentially can equidistantly be spaced setting, can also be with
The setting of unequal spacing interval.
