Abstract
The utility model discloses a bilateral pressing belt wheel structure for synchronous belt transmission. The structure comprises a driving wheel, a driven wheel, and a synchronous belt which connects the driving wheel with the driven wheel and is used for transmitting power. The synchronous belt on two sides of the driving wheel and on two sides of the driven wheel is provided with two pressing belt wheel which are connected through an elastic device and respectively and correspondingly apply opposite or reversed acting force to the synchronous belt on the two sides of the driving wheel and on the two sides of the driven wheel. By means of the structure and the method that the two pressing belt wheel assemblies are connected through the elastic device, whether a synchronous belt wheel rotates forward or reversely in the transmission of the synchronous belt, the synchronous belt can automatically obtain accurate and the same pre-tension through transmission of the elastic device, the problem that installation and adjustment are not convenient due to the fact that the central distance between the driving wheel and the driven wheel is adjusted during the transmission of the synchronous belt is avoided, at the same time, the problem that the pre-tension of the synchronous belt is different due to the unavoidable fact that the synchronous belt wheel rotates forward and reversely when an unilateral pressing belt wheel structure during the transmission of the synchronous belt is adopted is solved, transmission precision of the synchronous belt is increased, and service life of the synchronous belt is prolonged.
Description
Technical field
The utility model relates to field of video monitoring, can automatically regulate the bilateral guide pulley structure of pre-tensioning in especially a kind of toothed belt transmission.
Background technique
At present, along with the fast development of Video Supervision Technique, it is more and more general that electric platform uses.And the The Cloud Terrace that front end is executed the task needs quick and precisely response signal, turn to rapidly the position that will monitor, this just requires the kind of drive of a kind of stable drive, precision and transmission efficiency height and compact structure, and toothed belt transmission is used to electric platform on a large scale as a kind of type of belt drive that possesses above-mentioned advantage.
The pretightening force problem of toothed belt transmission is that everybody compares problems of concern always, this key element plays vital effect to the life-span of presetting bit precision, robust motion and the Timing Belt of transmission, inaccurate pretightening force can cause the presetting bit precise decreasing, and robust motion descends and reduces the Timing Belt life-span greatly.The machining accuracy of controlling well with the synchronous pulley mating parts is the prerequisite that solves the inaccurate problem of Timing Belt pretightening force, and this prerequisite is no doubt important, but assembly precision does not improve equally and can't get a desired effect.The key element that affects assembly precision comprise the centre distance precision of motor and driving wheel quality of fit, driving wheel and follower and when installing two axles parallelism and be used for play of position rotating part and standing part two side bearings etc.
And the pre-tensioner mode of traditional Timing Belt is mainly two kinds: a kind of is to regulate the Timing Belt pre-tensioning by the centre distance of regulating the driving wheel follower; Another kind is to regulate the Timing Belt tension force at the one-sided installation Idle wheel of Timing Belt.In the above dual mode, the mode of regulating principal and subordinate wheel centre distance is relatively simple for structure, but when assembling, need to guarantee with the frock of special use principal and subordinate wheel centre distance size, but because the frock use is not rigorous, so can't be very accurately according to theoretical center apart from adjustment, in addition as run into Timing Belt because long-term use the and elongated needs are just cumbersome when readjusting centre distance; And another kind of mode, synchronous one-sided installation Idle wheel also has problems: because the motion state of electric platform is different from conventional machinery, this product requirement bidirectional rotation, this just causes the Timing Belt that is used in electric platform inside also is bidirectional-movement, slack list and pilled-in selvedge are exchanged when The Cloud Terrace conversion sense of rotation, and slack list and the exchange of pilled-in selvedge cause be positioned at the one-sided Idle wheel of Timing Belt be different to the tension force of Timing Belt, also there is certain irrationality in visible this pre-tensioner mode.
The model utility content
The technical problems to be solved in the utility model provide a kind of when positive and negative rotation Timing Belt all can obtain the toothed belt transmission bilateral guide pulley structure of identical pre-tensioning.
For addressing the above problem, a kind of toothed belt transmission bilateral guide pulley structure of the present utility model, comprise driving wheel, follower, and connect the Timing Belt that driven wheel is used for transferring power, it is characterized in that: the Timing Belt of described driven wheel both sides is respectively arranged with a guide pulley; Link to each other by elastic device between described two guide pulleys, and correspondence applies in opposite directions or reverse active force to the both sides Timing Belt respectively.
Described two guide pulleys are separately positioned on the outside of the Timing Belt of driven wheel both sides, and described elastic device is extension spring, and two guide pulleys are corresponding respectively to apply in opposite directions active force to the both sides Timing Belt.
Described each guide pulley is installed on the guide pulley axle center optical axis, and the two ends of this guide pulley axle center optical axis fix with an end of an extension spring respectively.
Two mounting arm of described each guide pulley axle center optical axis by being arranged on its two ends links to each other with mounting arm optical axis on being fixed on the guide pulley mounting base, and described mounting arm can drive guide pulley axle center optical axis and rotate around the mounting arm optical axis.
Be positioned at the mounting arm outside on the optical axis of described guide pulley axle center and offer the hook groove, an end of extension spring colludes in described hook groove.
The outside that is positioned at the hook groove on the optical axis of described guide pulley axle center is equipped with guide pulley axle center optical axis axle head split washer.
Be positioned at the mounting arm outside on the described mounting arm optical axis mounting arm optical axis axle head split washer is installed.
Adopt toothed belt transmission bilateral guide pulley structure of the present utility model, the mode that connects two pinch roller assemblies by elastic device, no matter make in the toothed belt transmission synchronous pulley positive and negative rotation, Timing Belt can both lean on the transmission of elastic device automatically to obtain accurate and identical pre-tensioning, avoided adopting in the toothed belt transmission the inconvenient problem of installation adjusting that principal and subordinate's two center distance of belt wheel bring of regulating, solved simultaneously in the toothed belt transmission that adopts one-sided guide pulley structure unescapable synchronous pulley positive and reverse return then the different problem of Timing Belt pre-tensioning that causes has improved the precision of toothed belt transmission and the life-span of Timing Belt.
