Abstract

The utility model discloses a belt tightening mechanism which comprises a driving wheel support seat and a driven wheel support seat, wherein the driving wheel support seat and the driven wheel support seat make relative motion along the direction of a connecting line between the centers of a driving pulley and a driven pulley; the driving pulley and the driven pulley are respectively arranged on the driving wheel support seat and the driven wheel support seat by a rotating shaft; and an adjusting bolt used for adjusting the distance between the driving wheel support seat and the driven wheel support seat is arranged between the driving wheel support seat and the driven wheel support seat. The belt tightening mechanism has the advantages that the distance between the driving wheel support seat and the driven wheel support seat can be adjusted by the adjusting bolt, so that a belt can be rapidly tightened, the tensile force needed by the normal work of the belt and the service efficiency of the belt are guaranteed, the replacement frequency and the failure rate of the belt are reduced, and the out-field using and maintenance costs of a product can further be lowered.

Description

Belt tightening mechanism
Technical field
The utility model relates to motor power and transmits controlling mechanism, especially relates to a kind of belt tightening mechanism.
Background technique
Have in belt gear at present without tightening mechanism, some employing wheel clampings.The phenomenons such as along with the increase of belt operating time, a certain amount of plastic deformation can appear in belt, if belt in time carries out tensioning without tightening mechanism, the tension force deficiency will appear in belt, skid finally cause transmission efficiency to reduce; Thereby cause more in maintenance frequency and maintenance difficulty is large and wheel clamping is more due to moving element, reliability is low, and wheel clamping makes belt bending times in identical all movement processes many, relatively extend the operating time of belt, reduced the working life of belt.
Summary of the invention
The utility model purpose is to provide a kind of simple in structure, easy to adjust, belt tightening mechanism of extending belt working life, improving transmission efficiency.
For achieving the above object, the utility model can be taked following technical proposals:
Belt tightening described in the utility model mechanism comprises driving wheel bearing and the follower bearing that relatively moves along driving pulley and driven pulley center line connecting direction; Described driving pulley, driven pulley are arranged on driving wheel bearing and follower bearing by rotating shaft respectively; Be provided with the adjustment bolt of adjusting its spacing between driving wheel bearing and follower bearing.
Described adjustment bolt is provided with adjusting nut and the tightening nut that is used in conjunction with.
Be provided with guide groove below described driving wheel bearing or follower bearing.
Described driving wheel bearing or follower bearing are provided with holding down bolt.
The utility model advantage is simple in structure, tighten the spacing of driving wheel bearing and follower bearing by adjusting bolt, realize tightening fast of belt, tension force that the belt normal operation is required and the utilization efficiency of belt have been guaranteed, reduce replacement frequency and the failure rate of belt, and then reduced the line using maintenance cost of product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, belt tightening described in the utility model mechanism comprises driving wheel bearing 3 and follower bearing 4, driving pulley 1, driven pulley 2 are arranged on driving wheel bearing 3 and follower bearing 4 by rotating shaft respectively, have on follower bearing 4 along the guide groove 8 of driving pulley 1, driven pulley 2 centerline directions, driving wheel bearing 3 is also fixed after guide groove 8 moves to certain position by holding down bolt 9; Be provided with between driving wheel bearing 3 and follower bearing 4 and adjust bolt 5; The adjustment direction of described adjustment bolt 5 is consistent with driving pulley 1 and driven pulley 2 center line connecting directions, described adjustment bolt 5 is provided with adjusting nut 6 and the tightening nut 7 that is used in conjunction with, adjust the spacing of driving wheel bearing 3 and follower bearing 4 by adjusting bolt 5, thereby fetch the distance of adjusting between driving pulley 1 and driven pulley 2, and then realize the extremely tension force of design of belt tightening, realize tightening fast of belt.
