Be equipped with the position circle between compact heap and spring sleeve. The utility model discloses maintenance duration is practiced thrift to pretightning force that can the automatically regulated belt, prevents the belt creep.
Description
Technical field:
This utility model relates to a kind of concrete mixer belt stretcher.
Background technology:
Conventional two threephase asynchronouses of concrete mixer drive, and driven by motor small belt pulley rotates, and small belt pulley imparts power to reductor by V belt. In use, due to variations in temperature with use the reason such as tired to there will be the situation of belt anamorphic stretching, this can cause that pretightning force can not meet instructions for use to belt, and the coefficient of friction of belt and belt pulley reduces, and causes belt creep, consequently, it is possible to damage belt. Belt damages not only brings direct economic loss, changes belt and must spend the plenty of time especially. If in use, it has been found that after belt creep, adopting manual adjustments, this also influences whether the use of concrete mixer, and is difficult to adjust in time.
Utility model content:
This utility model is in order to make up the deficiencies in the prior art, it is provided that a kind of concrete mixer belt stretcher, it is possible to be automatically adjusted the pretightning force of belt, saves maintenance time, it is prevented that belt creep, solves problems of the prior art.
This utility model be the technical scheme is that by the above-mentioned technical problem of solution
A kind of concrete mixer belt stretcher, including motor base and motor, motor is fixed on motor base, motor base is movably connected on blender tank body by the first bearing pin, also include tensioner, tensioner includes pole, pole one end is flexibly connected with blender tank body by the second bearing pin bottom motor base, the other end is provided with screw thread, screw thread is provided with hex nut and locking thin nut, the spring spool being set on pole it is provided with between hex nut and motor base, the spheric washer being set on pole it is provided with between spring spool and motor base, the spring being set on pole it is provided with in spring spool, the back-up ring and compact heap that are set on pole it is provided with between spring and hex nut.
Preferably, centring ring it is provided with between compact heap and spring spool.
This utility model adopts such scheme, and reasonable in design, by the co-operating between tensioner and motor base, it is possible to be automatically adjusted the pretightning force of belt, saves maintenance time, thus preventing belt creep.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure, the 1, first bearing pin, 2, motor base, 3, belt, 4, motor, 5, locking thin nut, 6, hex nut, 7, compact heap, 8, back-up ring, 9, spring, 10, spheric washer, 11, pole, the 12, second bearing pin, 13, spring spool, 14, centring ring.
Detailed description of the invention:
For knowing the technical characterstic that this programme is described, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of concrete mixer belt stretcher, including motor base 2 and motor 4, motor 4 is fixed on motor base 2, motor base 2 is movably connected on blender tank body by the first bearing pin 1, also include tensioner, tensioner includes pole 11, pole 11 one end is flexibly connected with blender tank body by the second bearing pin 12 bottom motor base 2, the other end is provided with screw thread, screw thread is provided with hex nut 6 and locking thin nut 5, the spring spool 13 being set on pole 11 it is provided with between hex nut 6 and motor base 2, the spheric washer 10 being set on pole 11 it is provided with between spring spool 13 and motor base 2, the spring 9 being set on pole 11 it is provided with in spring spool 13, the back-up ring 8 and compact heap 7 that are set on pole 11 it is provided with between spring 9 and hex nut 6.
Centring ring 14 it is provided with between compact heap 7 and spring spool 13.
During use, regulate hex nut 6 and locking thin nut 7, spring 9 is compressed by back-up ring 8 and compact heap 9, spring 9 drives spring spool 13 to compress spheric washer 10, spheric washer 10 compresses motor base 2, motor base 2 driving electric machine 4, motor 4 drives belt 3, thus regulating the tensile force of belt 3. In the work process of belt 3, if owing to the reasons such as variations in temperature and use fatigue there will be the situation of belt 3 anamorphic stretching, motor 4 drive motor base 2 rotates down around the first bearing pin 1, now, spring 9, owing to originally being compressed, at this moment can discharge some compression distances, drives spring spool 13 to be pressed against spheric washer 10, make motor base energy 2 stable on new position, complete the automatic adjustment of belt 3 tensioning. Thus ensureing that belt 3 can transmit enough power.
Above-mentioned detailed description of the invention cannot function as the restriction to this utility model protection domain, and for those skilled in the art, any alternate modification made to this utility model embodiment or conversion all fall within protection domain of the present utility model.
This utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
