The utility model has the advantages that with the action of the torsion spring, the tension force is worked on the transmission belt automatically via the tension wheel, thereby the stable transmission efficiency is ensured; the reliability and work efficiency of belt transmission are improved; the service life of the belt is prolonged; the accidents are prevented from happening due to the brake function of the tension device.
Description
Technical field
The utility model relates to a kind of drivign belt tension device, relates in particular to the belt stretcher that exchanges the series excited machine transmission.
Background technique
A.C. series motor (be generally 10000～30000rpm), and motor volume is little, cost is low, thereby is widely used in fields such as electric tool and garden instrument owing to its rotating speed height.And the output shaft of this type of instrument does not need so high rotating speed, therefore also need dispose speed reduction gearing.
At present, the belt transmission that generally adopts garden instrument realizes slowing down, and motor speed height, load weigh, and belt is subjected to the effect of predetermined tension, when it is operated, belt stretches a little, just causes the minimizing of belt tension, and belt fluffs easily, thereby after operation a period of time, thereby make belt slippage, very easily produce skidding, can cause excessive noise and wearing and tearing.Belt temperature rises even can cause can not stable operation, so that breaks down, and has influenced the normal use of entire equipment, has caused loss to the user.
Therefore, designing a kind of belt stretcher that exchanges the series excited machine transmission, will be an economic benefit and the significant technical task of social effect.
Summary of the invention
The purpose of this utility model provides a kind of belt stretcher that exchanges the series excited machine transmission, can significantly improve the bel-drivenn reliability, increase work efficiency, and guarantees the long-time normal operation of equipment.
The purpose of this utility model is achieved through the following technical solutions:
Exchange the belt stretcher of series excited machine transmission, it is characterized in that: this tension device comprises driving lever, torsion spring and Idle wheel, driving lever is fixed on the base of motor and can rotates around this locating stud by locating stud, one end of torsion spring is fixed on the driving lever, the other end of torsion spring is fixed on the spacing place of base, is an Idle wheel that matches with belt at the front end of driving lever.
Further, the belt stretcher of above-mentioned interchange series excited machine transmission, the surface of Idle wheel parallels with the surface of driving lever, and the center line of Idle wheel parallels with motor shaft center line, center transmission shaft line.
Further, the belt stretcher of above-mentioned interchange series excited machine transmission, the width of Idle wheel is consistent with the width of driving belt.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
1. simple and direct, compact, easy to operate, the reliable performance of the utility model structure; Under the effect of torsion spring, tension device applies tension force to drivign belt automatically by Idle wheel, guarantees that transmission efficiency is stable, has significantly improved bel-drivenn reliability and working efficiency, prolong the working life of belt, brought many convenience for user's maintenance;
2. the utility model tension device also has brake function, can in 3 seconds the mowing machine resistance be stopped, and avoids the generation of some contingencies effectively;
3. novel in design, scientific and reasonable, both kept the auto-tensioning of dynamo belt during work, reduced the positioning error between each train again, and helped traveling comfort and reduced the probability that abnormal sound produces, improved the work effect of belt tension; Social effect and remarkable in economical benefits, application prospect is fine.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Embodiment
As shown in Figure 1, exchange the schematic representation of series excited machine driving mechanism, helical gear 1 links to each other with the axle of motor 2, takes drive wheel 5 runnings to by driving belt, and drive wheel 5 links to each other with transmission shaft 4, so its energy is transferred on the external machinery (blade of using as mowing machine) by transmission shaft 4.
Motor 2 is under the situation of energising, the electric energy of motor is converted to mechanical energy, export by motor shaft, in operation process, because what adopted is belt transmission, so it has skidding to take place, in order to prevent and eliminate skidding in the transmission process, the utility model design belt stretcher, as shown in Figure 2, a locating stud 7, driving lever 6 promptly are set on the base 3 of motor, torsion spring 8 is fixed on the locating stud 7, and driving lever 6 can rotate around this locating stud 7, one end of torsion spring 8 is fixed on the driving lever 6, an other end of torsion spring 8 is fixed on the spacing place of base 3, at the front end of driving lever an Idle wheel 9 is installed, and Idle wheel 9 matches with belt 10.The surperficial keeping parallelism of the surface of Idle wheel and driving lever, and the center line of Idle wheel and motor shaft center line, center transmission shaft line also keep parallel to each other, and the width of Idle wheel is consistent with the width of driving belt.Idle wheel is under the effect of the restoring force of torsion spring, give 10 1 pretightening forces of belt, when long-play or other reasons and when producing the belt slack phenomenon, the restoring force of torsion spring plays a role, Idle wheel 9 compresses belt 10, produce tension force, make belt be in the angular range of a suitable envelope belt pulley, realize regulating automatically tensioning.
During concrete the application, because the effect of torsion spring 8, its Idle wheel 9 is pressed in driving belt 10, and remain a kind of tensioning state between the driving belt, when operation, when driving belt 10 takes place to become flexible, adjust Idle wheels 9 by torsion spring 8, thereby regulate the elasticity of belt voluntarily, make driving belt 10 be in desirable tensioning state all the time, so in the whole service process, avoid and eliminated the skidding of driving belt effectively.
What deserves to be explained is that Idle wheel also has brake function, garden instrument: as mowing machine the blade of wide 30～50mm, long 300～500mm, thick 2～3mm is arranged, its rotary inertia is quite big.For guaranteeing and satisfying and use requirement safely, can stop rapidly behind the mowing machine cut-off switch (fitness for purpose is in 3 seconds), and the time is short more good more, and the utility model Idle wheel can play braking action effectively, can in 3 seconds, the mowing machine resistance be stopped, prevent that effectively some contingencies from taking place.
In sum, unique, the novel structure of the utility model belt stretcher design, easy to use, bel-drivenn reliability and working efficiency have been improved, prolonged the working life of belt greatly, cost is low, function is remarkable, and economic benefit and social effect are remarkable, have higher popularization and application values.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
