Abstract
A leather belt stretch adjustment device comprises the leather strap wheel, sub leather strap wheel, drive leather strap connected with the former two, an adjusting platform connected to a main leather strap wheel, the said adjusting platform moves up and down with the fixed bracket connected with it. It is free from human adjustment to the strain force of the drive leather strap, saving inner space, ensuring long time stability of the strain force in the running of the machine to improve the utilization efficiency with reduced cost.
Description
Technical field
The present invention relates to a kind of in engineering goods the bindiny mechanism between main pulley and the secondary belt pulley, relate in particular to a kind of regulating mechanism of adjusting belt tension.
Background technique
Motor drives the main pulley motion in engineering goods, and main pulley drives secondary pulley movements again by belt.When if belt tension is crossed pine, belt and belt pulley will be skidded produce high heat, belt life will seriously shorten; If will cause the machine run load to strengthen during the belt tension tension, also will cause the belt fracture.This just needs a regulating mechanism to adjust the tension force of belt, and the effect of regulating mechanism is by the relative position of adjusting major and minor belt pulley and then adjusts the tension force of belt.
As seen from Figure 1: after mechanical assembly is by above-mentioned mounting mechanism installation, wherein regulates platform 7 and fix by first supporting frame 8, second supporting frame 9; And first supporting frame 8, second supporting frame 9 are fixed on the stationary platen 6; The tension force of belt moves up and down regulating and controlling platform relative position to adjust the tensioning degree of drivign belt 5 by adjusting tooth bar 4, plays the role of fastening by hold-doun nut 1, thereby determines the tension force of drivign belt when static state.And the changing value of the draw tension of drivign belt and displacement amount remains in the design load scope.If regulate main pulley 3 and the parallelism of secondary belt pulley 2 at end face, need to be posted by on the belt pulley end face with the batten of spirit level or straight flange, measure the distance of another belt pulley outer rim and ruler deviation, the distance value of deviation must be less than in the 1mm.The tension value of belt can pass through: a. directly reads quiet tension value (measuring by tensiometer); B. fixedly tension force is pulled to the standard displacement amount, adjusts setting value to confirm belt tension.Wherein: a
0Be the centre distance between the major and minor belt pulley, f is a stretching Zhang power, and Ea is a displacement amount.
But there are such two problems in this regulating mechanism: the first, and needing increases an adjusting platform 7 that links to each other with secondary belt pulley 2, has taken the confined space of mechanical inside; The second, after after a while, need artificially to adjust again, make troubles for the normal operation of machine.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of belt tension regulating mechanism, are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The drivign belt that the present invention includes main pulley, secondary belt pulley, links to each other with main pulley, secondary belt pulley; Also comprise an adjusting platform that links to each other with main pulley; The described adjusting platform that links to each other with main pulley is done upper and lower moving by coupled fixed support.
Compared with prior art, the invention has the beneficial effects as follows: the tension force of drivign belt need not artificial adjusting, and has saved the inner space, guarantees the tension force long-term stability of drivign belt in machine run, can improve the utilization efficiency of machine, reduce cost.
Description of drawings
Fig. 1 is the prior art belt tension regulating mechanism;
Fig. 2 is a structural drawing of the present invention;
Fig. 3 is adjusting platform 31 structural drawing that link to each other with main pulley among the present invention;
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
By Fig. 2, Fig. 3 as seen: the drivign belt 5 that the present invention includes main pulley 3, secondary belt pulley 2, links to each other with main pulley 3, secondary belt pulley 2; Also comprise an adjusting platform 31 that links to each other with main pulley 3; The described adjusting platform 31 that links to each other with main pulley 3 is done upper and lower moving by coupled fixed support 311.
The stressed basic principle of belt tension (as seen from Figure 2) among the present invention:
Fa＞Fa.dyn (Fa.dyn is the drivign belt dynamic tension)
Fw: always stressed;
Fa＝Fw*A/B；
LD0=2a+/2 (Dd1+Dd2)+(Dd2-Dd1)
2/ 4a LD0 is the datum length of belt;
A is that just the dead axle spacing also satisfies 0.7 (Dd1+Dd2) a≤2 (Dd1+Dd2)
Dd1 is that the diameter Dd2 of secondary belt pulley is the diameter of main pulley.
After mechanical assembly was by above-mentioned mounting mechanism installation, the tension force of belt was adjusted the tensioning degree of drivign belt by the relative position of adjusting main pulley.If the tension force of belt is failed to reach requirement and can be met the demands by adjusting the position of regulating the support bracket fastened adjustable lever on the platform 31.If regulate main pulley and secondary belt pulley parallelism at end face, need to be posted by on the belt pulley end face with the batten of spirit level or straight flange, measure the distance of another belt pulley outer rim and ruler deviation, the distance value of deviation must be less than in the 1mm.The tension value of belt is to determine the tension force of learning that belt is on-stream by the size of Fa.
Because the adjustment of tension force is adjusted by the gravity of main pulley 3 among the present invention, can omit in the prior art and the adjusting platform that links to each other with secondary belt pulley.After required tension force requires to satisfy, need not artificial adjusting again, guarantee the tension force long-term stability of drivign belt in machine run, can improve the utilization efficiency of machine, reduced cost.
