Description

Automatic tensioning device for roller furnace driving chain

Technical Field

The utility model particularly relates to an automatic tight device that rises of roller hearth furnace drive chain.

Background

In the chain transmission commonly used, because in the transmission process, chain and sprocket inevitable will rub and produce wearing and tearing, will lead to the chain to appear becoming flexible, if the chain can not rise by tension automatically this moment, can aggravate the wearing and tearing of sprocket chain after the chain is not flexible, under the long-term use for the life-span greatly reduced of sprocket chain influences the performance of equipment, and the chain can break away from the sprocket when serious, influences the operation of equipment.

Therefore, in order to solve the above technical problems, it is necessary to provide an automatic tensioning device for a roller furnace driving chain, so as to overcome the above drawbacks in the prior art.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, an object of the utility model is to provide an automatic tight device that rises of roller furnace drive chain, including tight axle, mount pad A, mount pad B, half tooth bolt, adjusting spring and sprocket structure that rises, the sprocket structure sets up on tight axle that rises, tight axle both ends that rise set up mount pad A and mount pad B respectively, mount pad A and mount pad B all set up the bulge, half tooth bolt has two, link up mount pad A and mount pad B bulge respectively and connect at tight axle that rises, adjusting spring sets up on half tooth bolt.

Preferably, the chain wheel structure comprises a tension chain wheel, a shaft retainer ring, a hole retainer ring and a bearing.

Preferably, the adjusting spring is arranged below a part where the half-thread bolt penetrates through the convex part of the mounting seat.

Compared with the prior art, the utility model discloses following beneficial effect has: the chain sets up at the sprocket structure, and sprocket structural mounting is on the tight axle that rises, and the spring is in compression state during initial position, gives the tight axle of rising a decurrent power through half tooth bolt to tight axle that rises, chain and sprocket structure itself just possess certain gravity, consequently when the chain is not hard up, the device can realize making the automatic rising of chain rise.

In the above figures, 1, a chain wheel structure, 2, a tensioning shaft, 3, mounting seats A and 4, mounting seats B and 5, an adjusting spring, 6, a half-tooth bolt, 11, a bearing, 12 and a tensioning chain wheel.

Detailed Description

In the following, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings provided in the embodiments of the present invention, and it is obvious that the described embodiments are only preferred embodiments of the present invention, not all embodiments. Based on the preferred embodiment of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention. The present invention will be described in further detail below.

In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. The foregoing definitions are for the purpose of facilitating the description of the invention and simplifying the description and are not intended to indicate or imply that the structure referred to must have a particular orientation, be constructed and operated in a particular orientation and therefore should not be considered limiting of the invention.

As shown in the figure, the utility model provides an automatic tight device that rises of roller furnace drive chain, including the tight axle 2 that rises that can reciprocate, set up the tight axle 2 that rises and be used for fixed mount pad A3 and mount pad B4, half tooth bolt 6, be used for providing the adjusting spring 5 of elasticity and set up the sprocket structure 1 of chain, sprocket structure 1 sets up on the tight axle 2 that rises, tight axle 2 both ends that rise set up mount pad A3 and mount pad B4 respectively, mount pad A3 and mount pad B4 all set up the bulge, half tooth bolt 6 has two, link up mount pad A3 and mount pad B4 bulge respectively and connect in tight axle 2 that rises, adjusting spring sets up on half tooth bolt 6.

The chain wheel structure comprises a tension chain wheel 12 provided with a chain, a retaining ring for a shaft, a retaining ring for a hole and a bearing 11 used for rotating the chain wheel.

The adjusting spring 5 is arranged below the through part of the half-tooth bolt 6 and the convex part of the mounting seat, so that the movement of the chain wheel is not influenced, the elastic force can be stably provided, and the replacement is also convenient.

In the use, the chain is installed in sprocket structure 1, sprocket structure 1 sets up on the tight axle 2 that rises, can reciprocate along with the tight axle 2 that rises, the tight axle 2 both ends that rises set up half tooth bolt 6, two half tooth bolts 6 can reciprocate at mount pad A3 and mount pad B4 respectively, drive tight axle 2 and reciprocate, this in-process is realized through adjusting spring 5 and gravity, the degree of tightness by the chain is from the automatic change, the process is that the chain is not hard up, because adjusting spring 5 is in compression state, consequently, begin to release elasticity, because the fixing base is fixed this moment, half tooth bolt 6 moves down, drive tight axle 2 that rises and move, consequently, sprocket structure 1 moves down, the chain passes sprocket structure 1 below, consequently, after sprocket structure 1 moves down, the chain is compressed tightly, thereby realize the automatic tight function that rises that the device possessed.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
