Abstract
The utility model relates to a novel and simple takeup for V-belt transmission. The adjustable device of pulley center can be cancelled when designing V-belt transmission, the limit transmission ratio of the belt driven can also be appropriately enhanced after using the device. The utility model has the advantages of simple designing procedure, convenient installment, dismounting and adjusting the belt tension, labor saving and long service life. The device has relatively large regulation range, does not occupy the extracardiac space of the V-belt both sides and has the universality in the belt transmission with the same radical.
Description
The utility model is a kind of belt stretcher in the v belt transmission.
During design v belt transmission now, must consider all that generally pulley center should be able to adjust, method is that the connection back-plane design with motor becomes parallelly to move or form that dead axle rotates.If when being subjected to spatial constraints not adjust centre distance, then install Idle wheel additional in the slack list of v belt one side by last method, and very inconvenient, regulation range is again little, can't adjust sometimes.
The purpose of this utility model is to provide a kind of simplicity of design, belt tension instrument easy to use, the not side of occupation of land.Embodiment below in conjunction with this device of description of drawings:
The utility model comprises two roller 1, left clutch cover 5 and right clutch cover 3 intermeshing clutch covers, connecting rod 7 and connecting rods 2 with some grooves parallel to each other.One end of connecting rod 7 is fixed on the left clutch cover 5, and the other end is fixed on the left end of the axle of a roller.One end of connecting rod 2 is fixed on the right clutch cover 3, and the other end is fixed on the right-hand member of the axle of another roller.Left and right clutch cover is formed by spring flange, spring, hexagon socket head cap screw 4 and nut combinations.The belt stretcher that assembles must keep three axis of two rollers and clutch cover parallel to each other, and the groove on two rollers aligns mutually, can not be offset the v belt of the visual various models of width of groove and making.Left and right clutch cover clutch end is made flexuose, so under the spring action in clutch cover, left and right clutch cover can only be the axle center one-way rotation with the hexagon socket head cap screw, thereby the angle of two connecting rods is diminished, two rollers rotate with connecting rod v belt two outer side surfaces are compressed to home record, if unclamp v belt, only need overcome spring pressure separates left and right sides clutch cover respectively to the left and right, the left and right clutch cover of counter-rotation can make two connecting rod angles increase then, and the roller that compresses v belt is unclamped.
This device in use two pinch rollers lays respectively at v belt both sides outer side surface, clutch cover is positioned at the v belt home record, so this device does not in use occupy the space outside the belt both sides, in addition, a retaining ring 6 is arranged on the clutch cover of this device,, can bear the part weight and the very little pulling force of this device so that be fixed on jobbie for example on the guard, in order to avoid in the belt transmission process, this device slides to the small belt pulley direction.The roller of this device, connecting rod, left and right sides clutch cover can use made such as engineering plastics, aluminium, steel, and other other parts can be selected standard fasteners for use.
Use this device to be than the advantage of prior art:
1. when designing the v belt transmission, can cancel the adjusting device of pulley center, thereby simplify design procedure.
2. convenient and strength-saving when installing, dismantling belt and adjusting its tension force.
3. in the nonadjustable transmission of pulley center, use this device can prolong belt working life.
4. after adopting this device, in v belt transmission design, can suitably improve limit velocity ratio.
5. this tension device regulation range is bigger.
6. in the belt transmission of identical radical, this tension device has versatility.
7. this device does not in use occupy space in addition, v belt both sides.
Claims (5)
1, a kind of tension device that is used for the v belt transmission, comprise a clutch cover, two rollers 1 that have some grooves, connecting rod 2 and connecting rod 7 is characterized in that clutch cover divides the clutch end of left clutch cover 5 and right clutch cover 3,5 and 3 to be meshed by ratchet, one end of connecting rod 7 is fixed on the left clutch cover 5, the other end is fixed on the left end of the axle of a roller, and an end of connecting rod 2 is fixed on the right clutch cover 3, and the other end is fixed on the right-hand member of the axle of another roller.
2, tension device as claimed in claim 1, the width of roller surface groove can be made into series product according to the v belt width of various models, and slot number is identical with the belt radical.
3, tension device as claimed in claim 1 is characterized in that having in the clutch cover endoporus cylindricality stage clip and a hexagon socket head cap screw 4.
4, tension device as claimed in claim 1, its roller and parallel to each other from connection cover three axis, two roller grooves align mutually.
5, tension device as claimed in claim 1 is characterized in that being with retaining ring 6 on left clutch cover 5 surfaces.
