Abstract

The invention relates a driving device of a heat treatment furnace, belonging to the technical field of heat treatment. The driving device comprises a support, a sliding supporting seat, a bearing, a driving roller, a standard bearing support, a chain wheel, a motor reducer, a T-series spiral bevel gear steering box and a crosshead shoe shaft coupling. The T-series spiral bevel gear sheering box and the crosshead shoe shaft coupling are arranged on the driving device on the basis of chain transmission, so that the synchronism of the driving roller can be ensured. The supporting end of two ends of the driving roller is supported by adopting the standard bearing support, a shaft has a certain axial moving capacity in the bearing support, the other end is supported by the self-made sliding supporting seat, and the shaft can slide freely under the influence of high-temperature heat loads. By adopting the driving device, the non-smoothness and damages to materials transported by the driving roller due to the deformation of the driving roller caused by the influence of the high-temperature heat loads and non-synchronous transmission caused by multi-stage chain transmission can be reduced to the utmost extent.

Description

A kind of heat treatment furnace transmission mechanism

Technical field

The invention belongs to the heat treatment technics field, a kind of heat treatment furnace transmission mechanism particularly is provided, be applicable to the thermal treatment of the seamless bottle type container of big capacity high pressure.

Technical background

Along with the propelling of process of industrialization, high energy consumption, high pollution, labor-intensive workshop-based factory will be eliminated, and the product that energy-conserving and environment-protective, mechanization degree and production efficiency are high is widely adopted.Heat treatment furnace is divided into stepped start-stop system heat treatment furnace and roller transmission heat treatment furnace by type of drive, it is to drive roller turn by motor reducer by chain drive that its middle roller transport heat is handled stove, also be to connect successively by chain drive between the roller, reach the purpose that roller-way transports the seamless bottle type container of big capacity high pressure.When roller-way was opened, when the fire door roller of heat treatment furnace began to rotate, the roller in the stove was not because chaindriven time-delay is also rotated, and this just causes the seamless bottle type container of the big capacity high pressure scuffing at high temperature of transporting; Live roll is (about 900 ℃) work at high temperature, and roller produces radial and axial gross distortion under the effect of external force, cause the contact of the seamless bottle type container of big capacity high pressure in transportation inhomogeneous, makes bottle type container cause damage.Above scuffing and damage may cause scrapping of bottle type container or increase cost because repairing.

Summary of the invention

The object of the present invention is to provide a kind of heat treatment furnace transmission mechanism, solved the quality of the seamless bottle type container of big capacity high pressure after thermal treatment, reduce because of roller-way distortion to, transmission is asynchronous, point of contact is few etc. that bottle type container is caused the problem of damage.Guarantee the transmission synchronism of roller-way in the heat treatment furnace, it is little to reduce the deflection of roller-way under the effect of high temperature (about 900 ℃), external force, finally reaches to guarantee the quality of the seamless bottle type container of big capacity high pressure after thermal treatment.

The present invention includes support 1, slide bearings 2, bearing 3, live roll 4, standard bar bearing 5, sprocket wheel 6, motor reducer 7, T series helix conical gear steering box 8, sliding cross coupling 9, minor axis 10.

Motor reducer) is placed on the middle part of whole transmission device, drive middle two T series helix conical gear steering boxs 8 by sprocket wheel 6 transmissions, remaining T series helix conical gear steering box 8 is connected with minor axis 10 successively by sliding cross coupling 9, carries out transmission; Each T series helix conical gear steering box 8 drives two live rolls 4 by chain drive;

Live roll 4 two end supports: an end adopts standard bar bearing 5 to support, and the other end is supported by self-control plain bearing housing 2.Two kinds of supporting bases all are fixed on the support 1, and support 1 firmly is connected with ground, guarantee that live roll 4 stablizes friction in transmission.

Live roll 4 of the present invention is the V-type live roll, and material selection heat-resistance high-strength degree stainless steel guarantees that the seamless bottle type container of big capacity high pressure straight line in heat treatment furnace at the uniform velocity passes through.

Be by sliding cross coupling (9) and minor axis 1 between each T series helix conical gear steering box 8 of the present invention) be connected successively, guarantee that the action of each T series helix conical gear steering box 8 is synchronous; Each T series helix conical gear steering box 8 drives two live rolls 4 by chain drive, has therefore guaranteed that also the action of each live roll 4 is synchronous, makes not wearing and tearing of the seamless bottle type container of big capacity high pressure transmission at high temperature.

Leave the free movement of live roll 4 in the standard bar bearing 5 of the present invention, in the equipment assembling process, adjust the axial location of live roll 4, make the alignment of V-type roller-way, guarantee that the seamless bottle type container of big capacity high pressure passes through smoothly.

Live roll 4 (about 900 ℃) under high-temperature condition can extend, stroke by calculating and actual measurement live roll, the slide bearings 2 of design sufficient size guarantees slide bearings 2 slide-and-guides ratio and slippage, and self-control plain bearing housing 2 can guarantee that live roll 4 freely stretches.

Of the present inventionly be a little that this device has added the synchronism that T series helix conical gear steering box and sliding cross coupling can guarantee live roll on chaindriven basis.The design's live roll two end supports one end adopts the standard rolling bearing seat supports, and axle has certain axial play momentum in bearing support, and the other end is by self-control sliding support seat supports, and axle is free to slide under the elevated temperature heat effects of load.This device can reduce to greatest extent the distortion of the live roll that causes owing to elevated temperature heat load influence asynchronous with transmission that the multiple strand chain transmission causes make the material that transports on the live roll steadily with to the damage of material.
