It sets.
Rotary part 50 generally includes rotating arm 6, and 6 inside of rotating arm is hollow tubular, the pivotable peace of cylindrical inner wall
It is filled on the outer diameter of axis 1, is rotated around axis 1.Since axis 1 and rotating arm 6 are usually metal material, rotary part 50 includes axis
Set 10 is set between axis 1 and rotating arm, the abrasion for solving axis 1 and 6 binding face of rotating arm and noise problem.
Bias piece 3, torque spring as shown in Figure 1 is generally concentric to be arranged in the periphery of axis 1, and is axially located fixed part
Between part 20 and rotary part 50, torque spring one end is connect with pedestal 2, and the other end is connect with rotating arm 6, and torque spring is opposite
In pedestal bias rotating arm 6, rotary part 50 is made to be rotated relative to fixed component 20.Limitation rotation is generally also set up in stretcher
The structure of gyration, no longer describes one by one here.Washer 15 is also provided in the present embodiment between torque spring and pedestal 2, is used
In the abrasion of reduction pedestal and spring binding face, while certain damping action is generated together with axle sleeve 10.
There is eccentric adjusting part 12 eccentric shaft, the setting that the eccentric shaft of the eccentric adjusting part 12 is coaxially combined with axis 1 to pacify
During dress, the axis for adjusting eccentric adjusting part 12 is used for the eccentric position of adjustment axis 1, and then can adjust the tensioning of stretcher
Power.
Pulley assemblies 40 include belt wheel 9 and bearing 8, and bearing 8 is installed to the outer diameter of rotating arm 6, and can be revolved around rotating arm 6
Turn.The present embodiment improves the stability of stretcher work, is also provided with resistance as shown in Figure 1, to increase the damping force of stretcher
Damping member 11, but this is not the limitation to this stretcher, and partial tension device does not include this component.
Pedestal 2 has the protruding portion A that radially extends, and having location hole e on protruding portion A, (Fig. 2 is blocked, specifically can be referring to
Shown in Fig. 4) and sign f, sign f is by taking groove as an example in this specific embodiment；Sign is alternatively circular hole.Rotation
It is provided with protruding portion B on arm 6, identifying hole c (being overlapped with location hole e in Fig. 2) is provided on protruding portion B.Generally pacify in stretcher
Before being filled to engine, identifying hole c is aligned with location hole e, is inserted into positioning pin 7, and positioning pin 7 overcomes the i.e. torque spring of bias piece 3
Biasing force makes the fixed component of stretcher be relatively fixed with rotary part；After stretcher is assembled to engine, positioning pin is extracted
7, bias piece forces tensioner arms to rotate, and adjusts bias adjustment part, and fixed stretcher makes stretcher in the collective effect of belt
Under, tensioner arms rotate to nominal position, at this time the groove alignment on the identifying hole c and protruding portion A on stretcher protruding portion B,
Join shown in Fig. 4, and then may determine that whether stretcher is in nominal position.
Fig. 3, Fig. 4 are the stretcher schematic diagram of second embodiment, this stretcher is being damped compared to first embodiment stretcher
Aspect has done further improvement, which includes fixed component 20, eccentric adjusting part 12, rotary part 50, bias piece 3 and
Pulley assemblies 40.
Fixed component 20 includes axis 1 and pedestal 2, and axis 1 is fixedly connected with pedestal 2, is installed mounted on engine by bolt
On the latter's engine support mounting surface of face.
Rotary part 50 includes rotating arm 6, and rotating arm 6 is pivotable to be installed to the outer diameter of axis 1, is rotated around axis 1.Rotation
Component 50 includes being set to axle sleeve 10 between axis 1 and rotating arm.
Bias piece 3, is co-axially located at the outer ring of axis 1, and is axially located between fixed component 20 and rotary part 50, bias
Part one end is connect with pedestal 2, and the other end is connect with rotating arm 6, bias rotating arm, and rotary part is made to be revolved relative to fixed component
Turn.
The setting that eccentric adjusting part 12 is coaxially combined with axis 1 adjusts the axis of eccentric adjusting part, is used for during the installation process
The eccentric position of adjustment axis 1, and then the tensile force of stretcher can be adjusted.
Pulley assemblies 40 include belt wheel 9 and bearing 8, and bearing 8 is installed to the outer diameter of rotating arm 6, and can be revolved around rotating arm 6
Turn.
The stretcher further includes the lower damping piece 4 being located on about 1 opposed end of axis, upper damping piece 11 and is arranged in lower resistance
Pressurized part between damping member and rotating arm 6, pressurized part can be with helical spring, butterfly spring etc., the plenum of the present embodiment
For part by taking waveform spring 5 as an example, waveform spring includes multiturn coil or vortex ring, and per circle coil or vortex ring all has waveform profiles, under
Damping piece 4 is loaded with upper damping piece 11 by compressed waveform spring 5, and stretcher is increased relative to first embodiment
Damping force can compensate abrasion and configuration tolerance, reduce manufacture difficulty, specific works side since waveform spring is localized contact
Formula and structure can refer to publication number：The Chinese patent of CN104822970A.
Fig. 3 shows that stretcher installs the diagrammatic cross-section to engine, and positioning pin 7, which is inserted into, according to Fig. 2 protrudes
In the identifying hole c of the location hole e and protruding portion B of portion A, stretcher rotary part is fixed relative to fixed component.
After Fig. 4 shows that stretcher is assembled to engine, extracts the state after positioning pin 7 and (explanations are omitted here belt figure
Show), it can judge whether to be aligned with sign f by the identifying hole c on protruding portion B, for identification the name adopted position of stretcher
It sets.
If 1 to shown in Fig. 4, in order to facilitate observation of, protruding portion B may be arranged as pointer form, when pointer is aligned with groove
When, stretcher is located at nominal position.
Alternatively, stretcher protruding portion B may be arranged as shown in Fig. 5, including tooling hole h, when dismantling stretcher,
Due to the biasing force of torque spring, location hole e is difficult that operation is aligned with identifying hole c, needs to reverse tensioner arms by external force, this
Shi Caiyong tools are inserted into tooling hole, and firmly pull tool makes rotating arm rotate, and when identifying hole c is aligned with location hole e, are inserted into positioning
Pin, stretcher are restored to state before assembly, are convenient for the dismounting of stretcher.
Embodiments above is not to this stretcher merely to understand the structure and working method of this stretcher
Limitation, the unsubstantiality improvement that those skilled in the art carry out on this basis are within the scope of the invention.
