Embodiment
Especially, hitch roll 4 is movably arranged on plate 3, has around at least one rotary freedom of pivot axis (it is eccentric about roll axis X4), as described later.Due to the motion between rear plate 3 and hitch roll 4, tension device 2 can have not isostructure.More specifically, tension device 2 has at least one mounting construction C1, for plate 3 being arranged on to the wall of motor, and tension band 1 not; And have effect structure C2, for being arranged on by tension force F tensioning, on hitch roll 4, be with 1, described tension force F is radially applied to described being with on 1 with controlled manner about axis X 4.Mounting construction C1 is presented in Fig. 1, and effect structure C2 is presented in Fig. 2 to 5.
Intensity in order to ensure plate 3 in the optimization at itself and hitch roll 4 lock seaming places, and avoid any friction risk with respect to the hitch roll 4 of plate 3 pivotables, the thickness of supporting part 33 is greater than the thickness of core 34.Thereby supporting part 33 forms protuberance on the front side of plate 3, and arrange and to have plane surface 331, this plane surface 331 is perpendicular to axle X31 and X32, and is orientated on the front side relative with hitch roll 4 of plate 3.And supporting part 33 arranges has through hole 36, this through hole has the axis X 36 that is parallel to axle X4, X31 and X32.This hole 36 is set up to screw thread (tapped), to receive for hitch roll 4 being remained on to the screw 6 on plate 3.Screw 6 extends along the axis X 4 overlapping with axis 36, and is provided with the screw head 61 on the front side that is positioned at hitch roll 4.
When hitch roll 4 is installed on plate 3, and screw 6 is while being positioned in opening 93 and 36, and axle X6 and X36 overlap, simultaneously parallel and about roll axis X4 radial disbalance.Thereby when screw 6 is not held against roller support 9, hitch roll 4 can be around pivot axis X6 rotation, pivot axis X6 is limited by screw 6, with respect to its axis X 4 bias.Preferably, hitch roll 4 can be moved by instrument being inserted to (blind) housing 97 of an end opening that is formed on surperficial 95 places in roller support 9 by operator.Alternatively, housing 97 is not an end opening, but the X4 that parallels to the axis is through roller support 9.
In fact, screw 6 and tapped hole 36 form locking device, for respect to plate 3, hitch roll 4 being locked in to the different structure of tension device 2, construct in particular in C1 and C2.
First, especially, when it gives the operator who is responsible for installation traction loop, hitch roll 4 is locked in the mounting construction C1 of Fig. 1.Then the hole 311 and 321 of plate 3 can be got involved in the front portion of tension device 2 by operator.Thereby allow and be convenient to the installation of plate 3 in engine wall.
And before tension band 1, and particularly when being with 1 to be stretched, hitch roll 4 may be locked in the effect structure C2 of Fig. 2 to 5.The hole 311 of plate 3 no longer can be got involved by the front portion of tension device 2 by operator.In this effect structure C2, by tending to locking device 6 and 36 releases with 1 effect of stress being applied on hitch roll 4, and thereby make hitch roll 4 turn back to mounting construction C1 or surpass mounting construction C1 from effect structure C2.These stress arrow Fc relative with arrow F in Fig. 2 schematically shows.In this case, no longer satisfactory with the operational risk in traction loop with 1 tension force.
By being provided for stoping hitch roll 4 to turn back to the anti-blocking device that returns of mounting construction C1 with respect to plate 3 from effect structure C2, the invention enables and can solve this defect.According to the present invention, these are anti-returns to blocking device and locking device 6 and 36 is discrete, and make in effect structure C2, to avoid hitch roll 4 around any rotation of pivot axis X6, particularly in the situation that locking device 6 and 36 is unlocked when tension device 2 uses.
When tension device 2 is assembled, projection 98 is accommodated in the peripheral recess 37 on the outward edge of the supporting part 33 that is formed on exclusively plate 3.More specifically, recess 37 is formed in the part 33 at surperficial 331 places, on the radially relative edge of the axis X 36 of the front side with plate 3.Preferably, recess 37 is formed at the most on 1/4th of girth on the surface 331 of part 33.
In the example of Fig. 3, recess 37 comprises inclined-plane 37a, the front side of its slave plate 3 orientation, and tilting along chamber 37 so that the gap between inclined-plane 37a and surface 94 along with the end 32 of slave plate 3 away from and reduce.Recess 37 has parallelepiped section along comprising in the axial cross section of planar interception of axis X 6, and described section develops along plane of inclination 37a.Recess 37 is being for circular sector (circular sector), unless when cutting planes and plane of inclination 37a are when crossing about axis X 6 in cross section radially.
In this fan-shaped end that approaches end 31 most of recess 37, this recess 37 comprises chamber 38, and plane of inclination 37a exposes in chamber 38.In the example of Fig. 3 to 5, this chamber 38 comprises a planar side, and it extends perpendicular to surface 331 and connects by being parallel to before the planes of extending on surface 331.In the present circumstance, the side of chamber 38 and having above and the side of projection 98 and corresponding layout and size below.
When tension device 2 is in effect structure C2, projection 98 is accommodated in chamber 38, and wherein their faces respect to one another abut each other, as shown in Figure 3.Thereby the machinery by described chamber 38 and projection 98 coordinates, hitch roll 4 is stoped automatically around any rotation of the pivot axis X6 being limited by screw 6 and chamber 93.In other words, chamber 38 and projection 98 form hitch roll 4 about the anti-blocking device that returns of plate 3.Chamber 38 formations belong to the protruding anti-of plate 3 and return to element, and projection forms the recessed anti-element that returns that belongs to hitch roll 4.Chamber 38 and projection 98 axially form with respect to axis X 6.
In this stage, it should be noted, in order to be converted to effect structure C2 from mounting construction C1 when locking device 6 and 36 is unlocked, the operator X6 that hitch roll 4 and plate 3 must be paralleled to the axis divides out.Otherwise projection 98 abuts the inclined-plane 37a of recess 37, and can no longer stretch in chamber 38.If separated with plate 3, hitch roll 4 can be around axis X 6 pivotables, and projection 98 can low location relative to chamber 38.After making the more close plate 3 of hitch roll 4, in acting on structure C2, the anti-blocking device 38 and 98 that returns stops hitch rolls 4 to turn back to mounting construction C1 automatically, and no matter locking device 6 and 36 locks or releases, and needn't force operator that its instrument is remained in hole 97.Thereby operator is more practical and more do not handle tension device 2 not tiredly.
Finally, for tension device 2 being locked in effect structure C2, operator uses fastened tools (for example screw-driver) that appointment moment of torsion is applied on screw head 61. Anti-return blocking device 38 and 98 therefore with locking device 6 and 36 complementations, improve thus tension device 2 performance in time.
