Abstract
The utility model relates to the improvement on a belt transmission device. The belt transmission device is characterized in that: pairwise driving wheels are oppositely arranged on both sides of a driven wheel respectively. Therefore, the single side radial force of a driven shaft is balanced, the structure of the driven shaft is simplified, the entire equipment runs stably and reliably and defects caused by the single side radial force produced by the driven shaft due to single side arrangement of the driving shaft are overcome. The structure is particularly suitable for high-power suspension shafts.
Description
Technical field
Model utility is the improvement to belt driver, and relating in particular to a kind of follower shaft does not have the radially belt driver of side force, is specially adapted to the transmission of high-power hanging shaft band.
Background technique
The band transmission is to utilize the flexibility band that is stretched on the belt wheel, by friction or the engagement between band and wheel, a kind of mechanical transmission of transmitting movement or power between diaxon (or multiaxis).It has simple in structure, and stable drive can cushion absorbing, can need not lubricate growing transferring power between distance, and is cheap, and safeguards characteristics such as easy, and particularly high-power hanging shaft is widely used in mechanical transmission.
The setting type of band transmission, band transmission---the pleasure boat transmission that the opening transmission is arranged, intersect transmission, semidecussation transmission, the driving of parallel axes that Idle wheel is arranged, the concurrent aces transmission that guide wheel is arranged, multi-driven gear transmission, move with shift fork.More than various band transmission setting types, all be that drive pulley is arranged at follower one side, follower shaft produced one-sided pulling force, make driven shaft be subjected to bigger radially side force thereby cause, radially side force makes the centroclinal centre-of gravity shift that causes of hanging shaft, causes the vibration equipment aggravation; Driven shaft is subjected to more radially side force for a long time, and particularly transmission power is bigger, and whole axle construction is had wearing and tearing and destruction, thereby may make entire equipment produce vibrations or damage, and the infringement that this vibration causes is even more serious for the transmission of high-power hanging shaft band.Though strengthen the diameter of driven shaft, can reduce radially side force, can cause the complexity of cost increase and structure.Above-mentioned deficiency has the improved place of being worth.
The model utility content
The model utility purpose is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can effectively overcome driven shaft and be subjected to the big radially belt drive unit of side force.
The model utility purpose realizes that main the improvement being to adopt two driving wheels, about be arranged on the both sides of driven shaft, offset the one-sided radial force of driven shaft with this, reach the radial force balance, overcome the deficiencies in the prior art, realize the model utility purpose.Specifically, the model utility belt drive unit comprises driving wheel and follower, with the belt that is connected both transferring power, it is characterized in that driving wheel becomes two follower both sides that are placed in relatively respectively.
The described connection drivign belt of model utility is prior art, can be flat belt, also can be many narrow belts, vee belt for example, tooth form synchronous belt or the like.
Driving wheel Cheng Shuan, according to the transmitted power requirement, can be for example 2,4,6 ..., they are placed in respectively (each is to being called both sides) around the driven shaft.
Said splitting, a kind of driving wheel of more preferably complying with is symmetrical arranged, and offset drive is to side force so fully.
The model utility belt driver, with respect to prior art, owing to will originally place the driving shaft of driven shaft one side, adopt into two-phase to the follower structure on two sides that is placed in, thereby balance the one-sided radial force of driven shaft, and can make the driven shaft designs simplification, the entire equipment running is steadily reliable, overcome because of the one-sided setting of driving shaft makes driven shaft and produce the defective that one-sided radial force is brought, this structure is especially suitable for high-power hanging shaft especially.
Optimize specific embodiment below in conjunction with one; model utility essence is further understood in exemplary illustration and help; but embodiment's detail only is for model utility is described; do not represent model utility design whole technological schemes down; therefore should not be construed as the total technological scheme of model utility is limited; some are In the view of the technician; the unsubstantiality that does not depart from the model utility design increases and/or change; for example change or replace, all truely use novel protected scope so that technical characteristics with same or similar technique effect is simple.
Description of drawings
Accompanying drawing is a model utility belt driver structural representation.
Embodiment
Embodiment: referring to accompanying drawing, the model utility belt driver is included on the mounting bracket 3, about driven pulley 6 is arranged in the middle of the motor 1 that is provided with and drive pulley 2, two drive pulleys 2, connect by belt 5 respectively, and belt stretcher 4 respectively arranged.
In addition, initiatively skin wheel band can also be 4, is the cross setting around driven shaft.
To those skilled in the art; under this patent design and specific embodiment enlightenment; some distortion that can directly derive or associate from this patent disclosure and general knowledge; those of ordinary skills will recognize also can adopt additive method; or the substituting of known technology commonly used in the prior art; and the mutual various combination between feature; the for example change of drivign belt; the change of driving wheel logarithm; or the like unsubstantiality change, can be employed equally, can both realize this patent representation function and effect; launch for example no longer one by one to describe in detail, all belong to this patent protection domain.
Claims (2)
1. belt drive unit comprises driving wheel and follower, with the belt that is connected both transferring power, it is characterized in that driving wheel becomes two follower both sides that are placed in relatively respectively.
2. according to the described belt drive unit of claim 1, it is characterized in that driving wheel divides to be changed in pairs to comply with driving wheel and be symmetrical arranged.
