Abstract
The utility model relates to an automatic tensioning mechanism for an open-loop synchronous belt, which comprises a base, wherein a tooth-shaped plate is fixedly mounted on the base; a press plate is arranged on the tooth-shaped plate; a belt tightness adjusting bolt is arranged between the tooth-shaped plate and the press plate; a fastening adjusting pin is arranged between the press plate and the base; a moveable wedge block is inclined to one side of the press plate; the moveable wedge block is leaned against a wedge base and can slide along a contact surface of the wedge base; the wedge base is fixedly mounted on the base; a countersunk slot is arranged on the moveable wedge block; a compensating bolt passes through the countersunk slot and is fixed on the wedge base; a spring is sleeved on the compensating bolt; and the spring is located between the head part of the compensating bolt and the countersunk slot. A spring flexible structure is adopted by the automatic tensioning mechanism for the open-loop synchronous belt, the defects of belt loosening and influence on the transmission efficiency caused by the flexibility of a transmission belt after working for a long time during the working process of an open-loop synchronous wheel set are effectively overcome; the whole automatic tensioning mechanism automatically compensates for the loosening condition caused by the stretching of the belt; the structure is simple; and the operation is easy.
Description
Technical field
The utility model belongs to the mechanical transmission technical field, specifically just relates to a kind of open loop Timing Belt automatic tensioning mechanism.
Background technique
The synchronizing wheel transmission is provided with equidistant tooth by an interior perimeter surface endless-belt is formed with the belt wheel with respective teeth, during operation, be meshed with the teeth groove of belt wheel with tooth and transmit motion and power, it is to combine the separately newtype of belt drives of advantage of belt transmission, the transmission of chain driving gear.
Synchronizing wheel is used widely as common a kind of kind of drive, because synchronizing wheel often adopts belt transmission, belt uses through long-time, belt self often has stretchability, the belt that is enclosed within on the synchronizing wheel can relax, can't closely be attached on the synchronizing wheel, usually for the toothed belt transmission group of closed-loop structure, the Idle wheels that adopt carry out tensioning to belt more, and for the Synchronous Transmission group of open loop structure, although also usually prevent belt slack with Idle wheel, whole apparatus structure is complicated, and it is larger to take up room.
The model utility content
The purpose of this utility model provides a kind of open loop Timing Belt automatic tensioning mechanism, can effectively prevent in the synchronous wheels work of the open loop engineering, drivign belt is because self stretchability of working long hours causes belt slack, affect transmission efficiency, the relaxed condition that causes after whole automatic tensioning mechanism auto-compensation belt is flexible.
Technological scheme
In order to realize above-mentioned technical purpose, the utility model designs a kind of open loop Timing Belt automatic tensioning mechanism, it is characterized in that: comprise pedestal, the fastening adjustment pin, the belt tension adjusting screw, castellated plates, pressing plate, wedge mount, movable voussoir, spring, compensation screw and the second screw, castellated plates is installed on the pedestal, pressing plate is housed on the castellated plates, the belt tension adjusting screw is housed between castellated plates and pressing plate, the fastening adjustment pin is housed between pressing plate and pedestal, the pressing plate one side movable voussoir that reclined, movable voussoir leans against on the wedge mount, can be along sliding with the wedge mount surface of contact, wedge mount is installed on the pedestal, has the countersunk head slotted eye on the movable voussoir, and the compensation screw passes the countersunk head slotted eye and is fixed on the wedge mount, cover has spring, spring to be positioned between compensation screw head and countersunk head slotted eye on the compensation screw.
Described spring is in compressive state.
It is the miter angle inclined-plane that described movable voussoir leans against on the wedge mount with the wedge mount surface of contact.
Described wedge mount is screwed and is contained in pedestal.
Beneficial effect
The utility model adopts the spring flexible structure effectively to prevent in the synchronous wheels work of the open loop engineering, drivign belt is because self stretchability of working long hours causes belt slack, affect the shortcoming of transmission efficiency, the relaxed condition that causes after whole automatic tensioning mechanism auto-compensation belt is flexible, simple in structure, processing ease.
Description of drawings
Accompanying drawing 1 is plan view of the present utility model.
Accompanying drawing 2 is plan views of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Shown in attached Fig. 1 and 2, a kind of open loop Timing Belt automatic tensioning mechanism, it comprises pedestal 1, fastening adjustment pin 2, belt tension adjusting screw 3, castellated plates 4, pressing plate 5, wedge mount 6, movable voussoir 7, spring 8 and compensation screw 9, castellated plates 4 is installed on the pedestal 1, pressing plate 5 is housed on the castellated plates 4,5 of castellated plates 4 and pressing plates are equipped with belt tension adjusting screw 3,1 of pressing plate 5 and pedestal are equipped with fastening adjustment pin 2, the pressing plate 5 one sides movable voussoir 7 that reclined, movable voussoir 7 leans against on the wedge mount 6, can be along sliding with wedge mount 6 surface of contact, wedge mount 6 is installed on the pedestal 1, has the countersunk head slotted eye on the movable voussoir 7, and compensation screw 9 passes the countersunk head slotted eye and is fixed on the wedge mount 6, cover has spring 8, spring 8 to be positioned between compensation screw 9 heads and countersunk head slotted eye on the compensation screw 9.
Described spring 8 is in compressive state.
It is the miter angle inclined-plane that described movable voussoir 7 leans against on the wedge mount 6 with wedge mount 6 surface of contact.
Described wedge mount 6 usefulness screws 10 are installed on the pedestal 1.
Working procedure of the present utility model is: open loop Timing Belt one end is fixed, and the other end is fixed on the castellated plates 4; At first with 3 lockings of belt tension adjusting screw, pressing plate 5, Timing Belt and castellated plates 4 just are combined into an integral body like this; After fastening adjustment pin 2 locking, Timing Belt just can only left and right displacement and play up and down.Wedge mount 6 is screwed on pedestal 1, lock screw, and Compress Spring 8, movable voussoir 7 will produce displacement to the right, moves right thereby promote Timing Belt, plays tension.Because spring 8 is compressed, its elongation can compensate the tensile buckling that Timing Belt produces after work a period of time, thereby plays the function of auto-tensioning.
The utility model adopts the spring flexible structure effectively to prevent in the synchronous wheels work of the open loop engineering, drivign belt is because self stretchability of working long hours causes belt slack, affect the shortcoming of transmission efficiency, the relaxed condition that causes after whole automatic tensioning mechanism auto-compensation belt is flexible, simple in structure, processing ease.
