Abstract
The utility model discloses a tension device for belt transmission. The tension device for belt transmission comprises a bottom board. An upper wedge block and a lower wedge block are arranged on the bottom board from top to bottom, wherein the opposite slopes of the upper wedge block and the lower wedge block are adapted to each other. Horizontal guide bars are arranged on the portions, at the two sides of the lower wedge block, of the bottom board respectively. A perpendicular through hole is formed in one side of the upper wedge block. A perpendicular guide column is arranged in the perpendicular through hole in a sleeved mode. The bottom of the perpendicular guide column is arranged on the bottom board. A threaded hole is formed inwards in the front wall of the lower wedge block. An adjusting screw is screwed in the threaded hole. The portion, extending out of the lower wedge block, of the adjusting screw is sleeved with a fixing block in a sliding mode. The bottom of the fixing block is fixedly connected with the bottom board. The portions, located at the two sides of the fixing block, of the adjusting screw are respectively and fixedly connected with a locating ring. The tension device for belt transmission has the advantages that the structure is simple, operation is stable, tension operation can be conducted conveniently after a belt is operated for a time and loosened, and the belt can be rapidly replaced after the belt is damaged.
Description
Technical field
The utility model relates to belt gear field, especially relates to a kind of for bel-drivenn tension device.
Background technique
Belt transmission is widely used at construction machinery industry, for belt drive system, all requires to install additional tension device, and the tension force to endless-belt in use regulates, to prevent the generation of skidding, to ensure that security of system moves reliably.Current tensioning device structure complexity, operation inconvenience, can not effectively regulate belt.
Summary of the invention
The utility model object be to provide a kind of can be easily to the belt after lax carry out tensioning for bel-drivenn tension device.
For achieving the above object, the utility model can be taked following technical proposals:
Described in the utility model for bel-drivenn tension device, comprise the tension device body being arranged between prime mover bearing and prime mover; Described tension device body comprises the base plate being arranged on described prime mover bearing, is respectively arranged with the upper and lower wedge-shaped blocks that relative inclined-plane adapts on described base plate from top to bottom, on the base plate of described lower wedge-shaped blocks both sides, is respectively arranged with horizontally-guided bar; Wedge-shaped blocks one side offers vertical through hole on described, is set with vertically-guided post in described vertical through hole, and described vertically-guided column bottom is arranged on base plate; Antetheca at described lower wedge-shaped blocks inwardly offers tapped hole, in described tapped hole, be bolted with adjustment screw rod, on the adjustment screw rod that extends lower wedge-shaped blocks outside, flip sleeve is equipped with fixed block, described fixed block bottom is connected mutually with base plate, on the adjustment screw rod of described fixed block both sides, is fixed with respectively positioning ring.
Wedge-shaped blocks both sides vertically offer respectively bolt hole on described, are provided with adjustment bolt in described bolt hole, below described adjustment bolt and between described base plate, are provided with pad.
The utility model advantage is simple in structure, stable, can drive whole prime mover in the vertical direction under driving wheel to move and arrive desired location after effectively spacing.After lax in belt operation a period of time, can carry out easily tensioning, and can after belt damages, change fast.

Embodiment
As shown in Figure 1, 2, 3, described in the utility model for bel-drivenn tension device, comprise the tension device body being arranged between prime mover bearing 12 and prime mover 13; Described tension device body comprises the base plate 1 being arranged on described prime mover bearing 12, on described base plate 1, be respectively arranged with the upper and lower wedge-shaped blocks 2,3 that relative inclined-plane adapts from top to bottom, on the base plate 1 of described lower wedge-shaped blocks 3 both sides, be respectively arranged with horizontally-guided bar 4; Wedge-shaped blocks 2 one sides offer vertical through hole on described, are set with vertically-guided post 5 in described vertical through hole, and described vertically-guided post 5 bottoms are arranged on base plate 1; Antetheca at described lower wedge-shaped blocks 3 inwardly offers tapped hole 6, in described tapped hole 6, be bolted with and adjust screw rod 7, on the adjustment screw rod 7 that extends lower wedge-shaped blocks 3 outsides, flip sleeve is equipped with fixed block 8, described fixed block 8 bottoms are connected mutually with base plate 1, on the adjustment screw rod 7 of described fixed block 8 both sides, are fixed with respectively positioning ring 9; Wedge-shaped blocks 2 both sides vertically offer respectively bolt hole on described, be provided with and adjust bolt 10 in described bolt hole, below described adjustment bolt 10 and between described base plate 1, are provided with pad 11.
Its working principle is: the utility model is arranged on prime mover bearing 12 of prime mover 13, in the time that belt 14 is lax, turn counterclockwise positioning ring 9, positioning ring 9 drives to be adjusted screw rods 7 and rotates under fixed block 8 spacing, descend simultaneously wedge-shaped blocks 3 the guiding of horizontally-guided bar 4 and spacing under do forward motion, at this moment the upper wedge-shaped blocks 2 coordinating with lower wedge-shaped blocks 3 the guiding of vertically-guided post 5 and spacing under do vertical motion, upper wedge-shaped blocks 2 drives with prime mover 13 of driving wheel and does vertical motion, after belt tension, between base plate 1 and upper wedge-shaped blocks 2, filling in pad 11 eliminates behind gap, tighten the adjustment bolt 10 of wedge-shaped blocks 2, loosen the operation of belt in contrast.The utlity model has simple in structure, stable, can effectively improve tensioning and loosen the effect of belt.
