Abstract
In order to solve the problem that a plurality of belts or chains are not evenly stressed at the same time in the tensioning process, the invention provides a passive hydraulic self-balancing adjusting and controlling device. The technical scheme adopted by the invention is as follows: (1) a group of cylinder tubes are arranged on the same cylinder body of the passive hydraulic self-balancing adjusting and controlling device, pistons and piston rods are arranged in the cylinder tubes; one end of each piston rod is connected with each piston inside the cylinder tube, and the other end of each piston rod is connected with an adjusting and controlling support outside the cylinder tube; (2) an adjusting and controlling wheel is arranged on the adjusting and controlling support; and (3) the other sides of the pistons for mounting the piston rods are communicated with each other among the group of cylinder tubes. The passive hydraulic self-balancing adjusting and controlling device of the invention has the advantages of simple structure and high practicability and provides guarantee for the continuous production of the follow-up station.
Description
Technical field
The present invention relates to the hydraulic self-balancing adjusting and controlling device that uses in a kind of Hydranlic tensioner, particularly a kind ofly can carry out a kind of passive hydraulic self-balancing adjusting and controlling device that tensioning is regulated to many belts or chain simultaneously.
Background technique
At present, known belt, chain tension are to adopt directly to regulate the relative position of belt pulley, sprocket wheel or use common Idle wheel, make it tensioning, thereby make belt, chain ability proper functioning, realize transferring power, conveying material etc.Because the foozle of belt and chain; Original tensioning mode is difficult to guarantee that many belts, chains reach the conformity of tensioning; Cause the tension force of belt, chain inhomogeneous, making it can not balanced transferring power, steady conveying material, and follow-up station is caused adverse influence.
Summary of the invention
In order to overcome the deficiency of existing belt, chain tension structure, it is simple to the invention provides a kind of tensioning device structure, can make power tensionings such as many belts, chain, the power tension device such as hydraulic self-balanced of balanced transferring power, balanced conveying material.
The present invention realizes that the technological scheme that goal of the invention adopts is: (1), described balance adjustment control gear is provided with one group of cylinder barrel on same cylinder body; Piston and piston rod are set in cylinder barrel; Piston rod one end is connected with piston in cylinder barrel, and the other end of piston rod is connected with the adjustment control set outside cylinder barrel; (2), adjustment control wheel is set on the described adjustment control set; (3), one group of cylinder barrel each other, the opposite side that piston rod is installed at piston is interconnected.
The invention has the beneficial effects as follows: simple in structure, practical.The quantity of tensioning wheel assembly and shape can be selected according to actual needs, utilize the hydro-cushion principle, realize simultaneously many belts or chain being carried out the tensioning adjusting.
2 points below advantage of the present invention also has: the one, when transferring power, can effectively utilize every belt, chain, balanced transferring power, the transmission efficiency of raising power reduces belt, chain damage that unbalance stress causes; The 2nd, when conveying material, can effectively utilize every belt, chain, steady conveying material, the mass transport of avoiding unbalance stress to cause is unbalanced, and follow-up station is caused adverse influence, guarantees the continous way production of follow-up station.
Description of drawings
Accompanying drawing 1 is the structural representation of one embodiment of the invention.
Accompanying drawing 2 is the structural representation of another embodiment of the present invention.
In the accompanying drawing, 1 is cylinder body, and 1-1 is a central housing, and 1-2 is a upper cylinder cover, and 1-3 is following cylinder cap, and 1-4 is a lubricating cup, and 2 be cylinder barrel, and 3 be piston, 4 piston rods, and 5 are the adjustment control set, 6 control for adjustment and to take turns.
Embodiment
Referring to accompanying drawing, it is simple to the invention provides a kind of tensioning device structure, can make power tensionings such as many belts, chain, the power tension device such as hydraulic self-balanced of balanced transferring power, balanced conveying material.The technological scheme that adopts is:
(1), described balance adjustment control gear is provided with one group of cylinder barrel 2 on same cylinder body 1, piston 3 and piston rod 4 are set in cylinder barrel 2, piston rod 4 one ends are connected with piston 3 cylinder barrel 2 in, the other end of piston rod 4 outside cylinder barrel 2 with adjust control set 5 and be connected.
(2), adjustment control wheel 6 is set on the described adjustment control set 5.
(3), one group of cylinder barrel 2 each other, the opposite side that piston rods 4 are installed at piston 3 is interconnected.
In the technological scheme of embodiments of the invention, described cylinder body 1 is made up of central housing 1-1, upper cylinder cover 1-2 and following cylinder cap 1-3, and upper cylinder cover 1-2 and following cylinder cap 1-3 are separately positioned on the two ends of central housing 1-1, constitutes central housing 1-1 enclosed construction.
In the technological scheme of embodiments of the invention, described upper cylinder cover 1-2 is provided with lubricating cup 1-4.
In the technological scheme of embodiments of the invention, it is 3-8 that described cylinder barrel 2 is provided with quantity.
Referring to accompanying drawing 1 and accompanying drawing 2; The present invention in use, according to the principle of hydro-cushion, when work piston rod 4 according to the tightness of belt or chain size to its active force; Driving piston 3 moves; Hydraulic oil through in central housing 1-1, the cylinder barrel 2 can transmit pressure mutually, keeps each piston rod 4 all to bear identical active force, when the active force of one of them piston rod 4 changes; Because the effect of hydraulic oil decomposes other piston rod 4 with it, realize the goal of the invention of self balancing.Realize regulating automatically tension force, the power tensioning such as reach, balancedly transmit, steadily carry.
The present invention does not need power source in use, and this device utilizes the principle of hydro-cushion, has designed unique texture, has guaranteed power tensionings such as this device, thereby has realized balanced transferring power, balanced conveying material.
