1. a kind of dust absorption fan belt tension self-reacting device, including lubricating cup (1), opening nut (2), locking packing ring (3), bearing(4), belt wheel (5), belt (6), wheel shaft (7), connecting plate (8), riser (9), branch pipe (10), support plate (11), regulation spring (12),Adjusting washer (disk) (13), retainer nut (14), locking nut (15), adjusting screw rod (16), stand plate (17), support plate (18), horizontal strokeSeat board (19), fan supporter (20), sliding slot board (21), attachment screw (22), the hole of connecting plate (8) one and wheel shaft (7) oneEnd is welded after coordinating, and with being welded after branch pipe (10) one end fits, branch pipe (10) other end coordinates with riser (9) hole in another holeAfter be welded and fixed, riser (9) bottom and support plate (18) weld, support plate (18) side with after support plate (11) weldingAn entirety is formed, support plate (18) bottom is connected by attachment screw (22) with sliding slot board (21), the sliding grooveThe bar-shaped trough that plate (21) is stuck in fan supporter (20) is interior and freely slidable, after the stand plate (17), thwart (19) weldingForm an entirety and be fixed on by screw on fan supporter (20), the belt wheel (5) passes through bearing (4), locking packing ring(3) nut (2) that, is open is fixed on wheel shaft (7) and contacts and rotate with belt (6), and wheel shaft (7) other end is provided with lubricating cup(1) coordinate to oil injecting lubricating bearing (4), the adjusting screw rod (16) and the hole of support plate (11), the screw with stand plate (17)Connect and axially position is carried out by locking nut (15), now, adjusting screw rod (16) tail end connects with fan supporter (20) sideFurther positioning is touched, the regulation spring (12) is placed between support plate (11) and adjusting washer (disk) (13), now, passes through retainer nut(14) adjusting washer (disk) (13) is positioned on adjusting screw rod (16) and spring is adjusted by the position adjustment of retainer nut (14)(12) thrust, it is characterized in that:

  • By wheel shaft (7), connecting plate (8), riser (9), branch pipe (10), support plate (11), support plate (18)The compact horn shape welding of composition one is overall, and the sliding slot board (21) of welding entirety bottom connection can be in fan supporter (20)Bar-shaped trough in slidably, the tensile force that belt wheel (5) is acted on when belt (6) becomes hour in use, adjusts spring(12) the welding whole slide can be promoted automatically and keeps the tensile force between belt wheel (5) and belt (6) to be basically unchanged, and avoid makingWith process frequently manual adjustment, when the long deformation of belt (6) usage time is excessive, the elongation of regulation spring (12) is excessiveTensile force can be caused insufficient, now, it is appropriate to adjust to adjust position of the retainer nut (14) on adjusting screw rod (16) againTensile force, the welding being made up of stand plate (17), thwart (19) is integrally fastened to fan supporter (20), for secured adjustedThe position of screw rod (16), when the horizontal component of tensile force is excessive or vibrations are excessive, adjusting screw rod (16) tail end and fan supporter(20) contact of side provides further positioning and supports that its center line is sharp in one after the connecting plate (8) is welded with riser (9)Angle, the wheel shaft (7), the axial line of adjusting screw rod (16) are in a right angle, and the bar shaped well width of the fan supporter (20) is more thanThe width of sliding slot board (21), and the bar shaped groove center line of fan supporter (20) and adjusting screw rod (16) centerline parallel.
