Abstract
The utility model relates to a tension sprocket of a hoist for a full-automatic continuous aluminum alloy hub heat treatment device, comprising a sprocket (1), a fastening nut (3), a fixing plate (4) and a rotating shaft (5). The tension sprocket is characterized in that two annular oil grooves (2) which have a certain space are arranged on a shaft body of the rotating shaft (5) where the sprocket (1) is arranged; left and right spiral oil grooves (2.1) which are communicated with the two annular oil grooves are turned between the two oil grooves; an oil inlet hole which is communicated with the annular oil grooves (2) on the rotating shaft is arranged on the sprocket; and an oil cup (6) which is filled with high temperature-resistant water-resistant lubricating grease is arranged in the oil inlet hole. By using the mechanism, the tension sprocket and the shaft in rotating operate flexibly no matter under the high temperature or quenching from the water.
Description
Technical field
The utility model relates to a kind of thermal treatment unit elevator chain wheel drive structure, especially a kind of tightener sprocket of full-automatic continuous aluminum alloy wheel hub thermal treatment unit elevator
Background technology
Full-automatic continuous aluminum alloy wheel hub thermal treatment unit, be a kind of no material frame aluminium alloy wheel hub thermal treatment unit, mainly form by major partss such as inlet transfer roller, inlet elevator, steel structure platform, solid smelting furnace, quenching elevator, quenching tank, aging oven inlet conveying workbench, aging oven, export platform, exit lifting machine, outlet transfer rollers.The wheel hub treating processes is by the conveying roller on the feeder, aluminium alloy wheel hub to be processed is delivered on the import elevator, by the import elevator aluminium alloy wheel hub is risen in the solid smelting furnace again, by the transmission roller on the elevator wheel hub is delivered on the transmission roller in the solid smelting furnace, (Gu smelting furnace is positioned on the steel platform of aging oven top), import elevator decline reposition then, the aluminium alloy wheel hub that is fed in the solid smelting furnace is divided into operation continuously on three layers of cylinder in solid smelting furnace, in stove, meet the requirements of and carry out solid fully molten the processing in the technological temperature, when aluminium alloy wheel hub is consolidated molten handling in consolidating smelting furnace after, quenching is fallen machine and is risen in the solid smelting furnace, by the conveying roller on the quenching elevator aluminium alloy wheel hub is received on the elevator, straight line is lowered in the water of quenching tank then, make aluminium alloy wheel hub carry out quench treatment in the water of certain temperature having, after finishing, quench treatment by the conveying roller of quenching elevator aluminium alloy wheel hub is delivered on the aging oven inlet worktable again, the elevator that quenches then restores playback, at this moment by the conveying roller of aging oven inlet worktable aluminium being closed wheel hub again delivers on three layers of cylinder in the aging oven, operation continuously on the conveying roller of aluminium alloy wheel hub in aging oven, in having the stove of aging temp, carry out ageing treatment.After handling, conveying roller on the aging oven export platform is received aluminium alloy wheel hub on the worktable, at this moment again by the exit lifting machine three layers of wheel hub on the export platform, the lifting action by elevator is respectively aluminium alloy wheel hub receiving on the outlet transfer roller in layer.This process is solid molten, quenching, the whole operations of timeliness thermal treatment that full-automatic successive has been finished aluminium alloy wheel hub.Full-automatic continuous aluminum alloy wheel hub after this improvement does not have material frame thermal treatment unit, though have material frame thermal treatment unit to compare with the continuous aluminum alloy wheel hub, in combustion gas energy consumption and comprehensive energy consumption, type of drive, motor configuration, UTILIZATION OF VESIDUAL HEAT IN, quenching efficiency equipment failure rate and level of automation aspects bigger use advantage is arranged all, but, some medium and small use enterprises are hung back because cost height, the maintenance cost in the use of equipment is excessive.For example: the effect of the quenching elevator in the full-automatic continuous aluminum alloy wheel hub thermal treatment unit is the solid molten wheel hub of handling well to be picked out to deliver in the quenching tank again quench, and wheel hub is delivered on the aging oven inlet worktable after having quenched again.It is in 535 ℃ the body of heater that roller driving chain wheel mechanism in this process on the elevator will arrive temperature in the solid smelting furnace, pick out wheel hub after, in 15 seconds, in water temperature is 80 ℃ the water of quenching tank, go immediately again.Because sprocket wheel expands with heat and contract with cold, tend to take place the motionless fault of tightener sprocket rotation.
The utility model content
The purpose of the present utility model: be intended to propose a kind of tightener sprocket of full-automatic continuous aluminum alloy wheel hub thermal treatment unit, avoid the generation of the motionless fault of tightener sprocket rotation.
The tightener sprocket of this full-automatic continuous aluminum alloy wheel hub thermal treatment unit elevator, comprise sprocket wheel, fitting nut, retaining plate, rotation axis, it is characterized in that: described rotation axis settles the axis body at sprocket wheel position to be provided with twice tool endless-oil groove at regular intervals, car goes out the left and right spiral oil groove that connects with two endless-oil grooves between the twice oil groove, and establish on the sprocket wheel one with rotation axis on the oil supply hole that connects of annular oil groove, the lubricating cup of the fire resistant water resistant lubricating grease of annotating is housed in this oil supply hole.
The tightener sprocket of this full-automatic continuous aluminum alloy wheel hub thermal treatment unit elevator that proposes according to above technical scheme, can make tightener sprocket and axle when rotating no matter after at high temperature still quenching in the water, can both go slick, effectively avoid tightener sprocket to change the generation of motionless accident.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is existing sprocket wheel tightener sprocket structural representation.
Among the figure: the left and right spiral oil groove 3-of 1-sprocket wheel 2-oil groove 2.1-fitting nut 4-retaining plate 5-rotation axis 6-lubricating cup
Embodiment
The tightener sprocket of this full-automatic continuous aluminum alloy wheel hub thermal treatment unit elevator that proposes according to above technical scheme, it is to being used for a kind of improvement of full-automatic continuous aluminum alloy wheel hub thermal treatment unit quenching hoisting appliance now, the tightener sprocket mechanism of this full-automatic continuous aluminum alloy wheel hub thermal treatment unit, comprise sprocket wheel 1, fitting nut 3, retaining plate 4, rotation axis 5, its improved method is: the method for employing is that the endless-oil groove 2 of the rotation axis 5 car bipassage rings of sprocket wheel 1 around whole rotation is installed on axle, car goes out a left side between the twice oil groove then, right-hand screw oil groove 2.1, and get on the sprocket wheel one with rotation axis on the oil supply hole that connects of annular oil groove 2, the lubricating cup of the fire resistant water resistant lubricating grease of annotating is housed in this oil supply hole.
During use waterproof and resistant to elevated temperatures again grease robbed regularly to get to oil and store in the lubricating cup in the oil groove, make tightener sprocket and axle when rotating no matter after at high temperature still quenching in the water, can both go slick.
