Abstract
The utility model relates to a permanent magnetism belt pulley tensioning ware, include band pulley, bearing, round pin axle, split pin, slide bar, screw, move magnetic path, anti crash pad, magnetostatic piece, magnetostatic seat, casing, screw rod, slipmat, mounting panel, gasket, nut, the band pulley passes through interference fit to be installed on the bearing, and the bearing is installed on the slide bar through the round pin axle to by split pin fixed pin axle, move the magnetic path and pass through the screw connection slide bar, the magnetostatic piece passes through the fix with screw on the magnetostatic seat, and the magnetostatic seat links firmly on the casing through the welding, the casing passes through the screw rod and connects the mounting panel to fix through gasket, nut, the slipmat is fixed respectively on casing and mounting panel, anti crash pad fixes on the magnetostatic piece, gapped between magnetostatic piece, magnetostatic seat and anti crash pad and the slide bar, can not touch each other at the gliding in -process of slide bar. The utility model discloses sensitive less to the temperature, when high temperature and low temperature, the tensile force of output is pretty much the same very much.
Description
Technical field
The utility model relates to a kind of permanent magnet pulley stretcher.
Background technique
In transmission, belt is comparatively general, for two pulley drive of fixed position, in use belt can elongate due to pulling force effect, thus cause skidding, therefore need tension device, stretcher uses the most frequently used, tension device the most widely exactly.Be characterized in keeping belt and belt wheel in transmission process, have suitable tension force, and increase the cornerite of small pulley, thus prevent belt from skidding on belt wheel and affecting normal transmission.The structure of stretcher is varied, it roughly comprises stationary structure and elasticity self-regulation structure, wherein the many employings of stationary structure fix adjustable belt pulley to regulate the tension force of belt, because it can not regulate Idle wheel automatically according to the belt degree of wear, and regularly will regulate Idle wheel manually, so use not extensive; Elasticity self-regulation structure many employings elastic member can control the tension force of belt by automatic rebounding, but the defect of the severe particularly king-sized environment of the temperature difference and elastic member self due to working environment, the spring-back force that elastic member is exported is change, thus causes the tension force exported also to be to change.Traditional tensioner pulley is generally that the restoring force by recovering original state after flow of metal provides tension force, can cause getting rusty and aging corrosion etc. of deformable metal, thus reduce the life-span of self in air during high humidity.
Model utility content
The purpose of this utility model is the defect overcoming at present existing belt tightener on the market, provides a kind of tensioner pulley that can automatically regulate, particularly a kind of permanent magnet pulley stretcher.
In order to achieve the above object, the utility model adopts following technical proposals:
A kind of permanent magnet pulley stretcher, comprise belt wheel, bearing, bearing pin, cotter pin, sliding bar, screw, dynamic magnetic patch, bumper, magnetostatic piece, magnetostatic seat, housing, screw rod, bath mat, mounting plate, pad, nut; Described belt wheel is arranged on bearing by interference fit, and bearing is arranged on sliding bar by bearing pin, and by cotter pin fixed pin shaft; Described dynamic magnetic patch is connected by screw sliding bar; Magnetostatic piece is fixed by screws on magnetostatic seat, and magnetostatic seat is connected on housing by welding; Described housing by screw rod connection plate, and is fixed by pad, nut; Described bath mat is separately fixed on housing and mounting plate; Described bumper is fixed on magnetostatic piece; Described magnetostatic piece, magnetostatic seat and have gap between bumper and sliding bar, can not mutually touch in the process that sliding bar slides.
Through above-mentioned improvement, the utility model design as compared with the past has following substantive distinguishing features and advantage:
The sensitivity of a kind of permanent magnet pulley of the utility model stretcher to temperature is less, and especially when high temperature and low temperature, the tension force of output is more or less the same.
Accompanying drawing explanation
Fig. 1 is general profile figure of the present utility model.
Fig. 2 is plan view of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, a kind of permanent magnet pulley stretcher, comprise belt wheel 1, bearing 2, bearing pin 3, cotter pin 4, sliding bar 5, screw 6, dynamic magnetic patch 7, bumper 8, magnetostatic piece 9, magnetostatic seat 10, housing 11, screw rod 12, bath mat 13, mounting plate 14, pad 15, nut 16; Described belt wheel 1 is arranged on bearing 2 by interference fit, and bearing 2 is arranged on sliding bar 5 by bearing pin 3, and by cotter pin 4 fixed pin shaft 3; Described dynamic magnetic patch 7 connects sliding bar 5 by screw 6; Be fixed on magnetostatic seat 10 by screw 6 for magnetostatic piece 9, magnetostatic seat 10 is connected on housing 11 by welding; Described housing 11 by screw rod 12 connection plate 14, and is fixed by pad 15, nut 16; Described bath mat 13 is separately fixed on housing 11 and mounting plate 14; Described bumper 8 is fixed on magnetostatic piece 9; Described magnetostatic piece 9, magnetostatic seat 10 and have gap between bumper 8 and sliding bar 5, can not mutually touch in the process that sliding bar 5 slides.
Working procedure of the present utility model is as follows:
Permanent magnet pulley stretcher is arranged on by near small pulley by four bolts, and belt wheel 1 contacts with V belt translation slack list and provides one to make slack list to the close tension force of pilled-in selvedge.Belt can be worn and torn, elongate because of the effect of driving force in V belt translation running, thus belt is skidded on belt wheel, now permanent magnet pulley stretcher will play its effect; The process of specific works is: because Action of Gravity Field can be folded down automatically after belt elongates, now dynamic magnetic patch 7 meeting of permanent magnet pulley stretcher be subject to an inside power under the attraction force effect of magnetostatic piece 9, this power can force dynamic magnetic patch 7 to move inward together with sliding bar 5, and be arranged on belt wheel on sliding bar 5 can to the outside tension force of the belt be folded down, thus belt is no longer dangled, prevent chain generation skidding, alleviate the wearing and tearing of belt.When causing the bob of receding side of belt in belt transmission process, can to the downward active force of one, the sprocket wheel on belt tightener when belt is beated downwards, if sliding bar 5 can move down when this active force is greater than the attraction force between magnetic patch, at this moment the bumper 8 be bonded on magnetostatic piece 9 by powerful cohesive material will be played a role, prevent the direct contact of dynamic and static magnetic patch, avoid because impact force is too large and crash magnetostatic piece 9.
