Embodiment
For the purpose, technological scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 2 is the utility model belt tension device embodiment's a plan view, Fig. 3 is the utility model belt tension device embodiment's a side view, as shown in Figures 2 and 3, the belt tension device of present embodiment mainly comprises tensioner support 16, expansion tightening wheel 11, axle 17, locking nut 18, bolt 19 and positioning device.
Wherein, tensioner support 16 is installed on the motor, and expansion tightening wheel 11 is fixed on the tensioner support 16 by axle 17.One end of axle 17 is fixed on the expansion tightening wheel 11 by locking nut 18, and this 17 long-round-shape duct of passing on the tensioner support 16 is connected on the bolt 19 the other end.Axle 17 is provided with tapped hole with bolt 19 connecting ends, and bolt 19 passes axle 17 tapped hole and is threaded with axle 17, and this is threaded can be so that axle 17 moves up and down the tensioner belt thereby drive expansion tightening wheel 11 moves up and down along with the rotation of bolt 19.The hole that bolt 19 the other ends pass on the tensioner support 16 is connected with tensioner support 16.
The main distinction point of the belt tension device of present embodiment and prior art belt tension device is that bolt 19 is different with the Placement of tensioner support 16.Bolt of the prior art 19 and tensioner support 16 be for flexibly connecting, and the set-up mode of expansion tightening wheel 11 and belt is construed as limiting; And the bolt 19 of present embodiment belt tension device is connected with tensioner support 16 axial restraints by positioning device, and this bolt 19 to rotate, can not carry out axial motion, thereby the set-up mode of expansion tightening wheel 11 and belt can freely be set only.
This bolt 19 can be for multiple with tensioner support 16 Placements, for example, bolt 19 passes the hole on the tensioner support 16, it can be provided with first limit position part in the upper-end surface in tensioner support 16 holes, for example, this first limit position part is used to prevent that bolt 19 from moving downward, and it can be the boss 20 greater than the hole.This boss 20 can be circular or other shapes, and this boss 20 also can be integrally formed with bolt 19, prevents that bolt 19 from moving downward.If boss 20 is structure as a whole with bolt 19, the bolt 19 that this can be had boss 20 when mounted penetrates in the hole on the tensioner support 16 from the top down, can move upward by locating piece 21 constraint bolts 19 at the another side of tensioner support 16 then, this locating piece 21 can be pin or spring collar.By being positioned at the top and following positioning device in the hole on the tensioner support 16, can realize limiting the axial motion of bolt 19, but can not limit the rotation of bolt 19.Bolt 19 can move up and down by rotating drive expansion tightening wheel 11.
In addition, bolt 19 can its diameter that is positioned at the lower end in tensioner support 16 holes be set to the diameter greater than tensioner support 16 holes, in the hole that bolt 19 that when mounted can this lower diameter is bigger penetrates on the tensioner support 16 from bottom to top, in the upper end that is positioned at tensioner support 16 holes second limit position part is set then, this second limit position part is used for caging bolt 19, prevent that bolt 19 from moving downward, it can be two nuts, thereby has limited the axial motion of bolt 19.
The belt tension device of present embodiment can be arranged on expansion tightening wheel 11 outside of belt in use, promptly changes the tensioner mode of belt.Can be referring to shown in Figure 4, Fig. 4 is the utility model belt tension device embodiment's an application state schematic representation.When using this belt tension device to carry out belt tension, expansion tightening wheel 11 can be arranged on the outside of belt.Belt 12 is walked around motor driving wheel 13, expansion tightening wheel 11 and compressor follower 14 successively, and wherein, motor driving wheel 13 and compressor follower 14 are positioned at the inside of belt 12, and expansion tightening wheel 11 is positioned at the outside of belt 12.
When needs are regulated tensioner belt 12, can rotating bolt 19, because bolt 19 and axle 17 be for being threaded, then spools 17 can drive expansion tightening wheel 11 and carry out bottom-up motion in the outside of belt 12, thus tensioner belt 12.And bolt 19 can be positioned device for example boss or locating piece etc. carry out axial restraint, make it can not carry out axial motion, comparatively firm.
The belt tension device of present embodiment is axially fixed on the tensioner support by the bolt that will be connected with the tensioner wheel shaft, this expansion tightening wheel can be arranged on the belt outside, belt is carried out bottom-up tensioner mode, take up room thereby when belt tension, saved greatly.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment's technological scheme of the utility model.
