Description
Technical Field
The utility model belongs to the technical field of the metallurgical rolling, a chain overspeed device tensioner is related to.
Background
In the steel rolling field of the metallurgical industry, a plurality of chain transmission devices are provided, the effective meshing tooth number with a chain wheel can be reduced after the abrasion of the chain is gradually increased, the transmission capacity is reduced, and the chain falls off and fails in transmission in serious conditions, so that how to ensure the reliable operation of chain transmission is particularly important.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a chain overspeed device tensioner, the effectual current chain drive that has solved leads to the chain to drop easily because the chain is lax, problem that production efficiency is low.
The utility model discloses the technical scheme who adopts is, a chain overspeed device tensioner, including the tensioning support, tensioning support swing joint adjustment mechanism, adjustment mechanism is provided with the take-up pulley, and the take-up pulley compresses tightly or relaxs the chain.
The utility model discloses a characteristics still lie in:
the tensioning support is provided with a transverse baffle which is movably connected with an adjusting mechanism.
The adjusting mechanism comprises an adjusting pull rod, the adjusting pull rod vertically penetrates through the transverse baffle and is limited by an adjusting nut, the adjusting pull rod is in threaded connection with the adjusting nut, the tail end of the adjusting pull rod is fixedly connected with a movable support, and a tensioning wheel is fixedly connected with the movable support.
The adjusting pull rod vertically penetrates through the movable support, and a pull rod locking ring is fixedly connected to the tail end of the adjusting pull rod and used for fixing the movable support.
The movable support is a U-shaped groove, and the tensioning wheel is fixedly connected in the U-shaped groove through a connecting shaft.
The beneficial effects of the utility model reside in that: firstly, on the basis of the original chain wheel and chain transmission, the chain is tensioned by adopting a tensioning mode, the meshing wrap angle of the chain wheel is increased, and the meshing tooth number of the chain and the chain wheel is increased, so that the transmission is more reliable, and the operation is more stable. Reducing the impact vibration and avoiding the resonance. Secondly, the tensioning chain wheel adopts an adjustable pull rod device, when the chain is gradually increased due to abrasion sag, the compression degree of the tensioning chain wheel can be synchronously adjusted, and thus, the reduction of the transmission capacity of the chain due to the abrasion of the chain can not be caused.
After a certain cold rolling plant adopts the structure provided by the invention, the stable operation of the coil conveying trolley at the designed speed is ensured, the use effect is good, and the production efficiency is improved. The structure can also be used for carrying out technical transformation on other existing chain transmission, belt transmission and the like, and can also provide reference for solving similar problems for other enterprises.
Drawings
Fig. 1 is a schematic structural view of the chain tensioner of the present invention;
fig. 2 is a sectional view a-a in fig. 1.
In the figure, 1, a tension bracket, 2, a chain, 3, an adjusting pull rod, 4, an adjusting nut, 5, a movable bracket, 6, a pull rod locking ring, 7, a tension wheel and 8, a transverse baffle plate.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a chain tensioning device, as shown in fig. 1-2, including tensioning support 1, tensioning support 1 is through 8 swing joint adjustment mechanism of horizontal baffle, and adjustment mechanism includes adjusting rod 3, and adjusting rod 3 runs through horizontal baffle 8 perpendicularly and is spacing by adjusting nut 4, and 3 threaded connection adjusting nut 4 of adjusting rod adjust 3 terminal fixed connection movable support 5 of pull rod, and 5 rigid couplings of movable support have take-up pulley 7. The tensioning wheel 7 is used for pressing or loosening the chain 2. The adjusting pull rod 3 vertically penetrates through the movable support 5, and the tail end of the adjusting pull rod 3 is fixedly connected with a pull rod locking ring 6 for fixing the movable support 5. The movable support 5 is a U-shaped groove, and the tension wheel 7 is fixedly connected in the U-shaped groove through a connecting shaft.
The working process of the utility model is as follows:
the lower end of the tension pulley 7 is meshed with the chain 2, the adjusting nut 4 is adjusted, the adjusting nut 4 is rotated in a specific forward direction, so that the adjusting pull rod 3 moves downwards, at the moment, the movable support 5 also moves downwards, the tension pulley 7 tightly presses the chain 2, a chain wheel meshing wrap angle is increased, the number of meshing teeth of the chain 2 and the tension pulley 7 is increased, and transmission is more efficient; adjusting the adjusting nut 4 again, rotating the adjusting nut 4 in a specific direction to cause the adjusting pull rod 3 to move upwards, at the moment, the movable support 5 also moves upwards, the tension of the tensioning wheel 7 and the chain 2 is reduced until the tension disappears, and at the moment, the tensioning wheel 7 or the chain 2 is convenient to replace.
In a word the utility model discloses chain tensioning device has realized the even running of chain through to chain drive's configuration optimization, has strengthened the practicality of equipment. The utility model discloses can popularize to in the majority adopts chain drive, belt drive's equipment, reinforcing driven reliability, the life-span of part has obtained effectual extension, can not just scrap because of the part is worn and torn a little, has saved manufacturing cost for the user.
