Abstract
A device for testing the service life of a tile line sun wheel comprises a frame, a servomotor, a motor bracket, an upper pressure roll shaft, a lower pressure roll, a roll shaft bracket and a protective casing, wherein the upper pressure roll shaft and a lower pressure roll shaft are arranged on the roll shaft bracket, and the lower pressure roll is arranged on the lower pressure roll shaft through a bearing; the servomotor is connected with a speed reducer, the output shaft of the speed reducer is connected with the upper pressure roll shaft, and a friction baffle strip is arranged on the lower pressure roll in the axial direction of the lower pressure roll; a to-be-tested tile line sun wheel is fixedly connected with the upper pressure roll shaft and in tight contact with the lower pressure roll; and the protective casing is arranged on the peripheries of the servomotor, the upper pressure roll shaft and the lower pressure roll. The device provided by the utility model adopts the servomotor to drive the to-be-tested sun wheel to rotate and enables the to-be-tested sun wheel to be in tight contact with the pressure rolls with friction strips to simulate the actual operating condition of the sun wheel, thereby testing the service life of the sun wheel, providing reference for actual production and avoiding production accidents.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to the workpiece proving installation in serviceable life, particularly a kind of watt device of line sun gear life test that is used for.
Background technology:
In the automatic tinuous production of corrugated board cardboard is carried out cutting and finished by transverse cutting unit, watt feed roller that the line transverse cutting unit uses is rubber sun gear structure, is light pressure wheel.Sun gear generally is the high-tension elastomeric material, requirement has extraordinary quality and can not weigh cardboard wounded, so the urethane rubber (PU material) of special formulation commonly used processes, it is 50 degree～60 degree that general shore hardness detects, have characteristics such as wear-resistant, friction factor height, guarantee at the long term life of producing in using, if its sun gear product quality defective (material or size etc.) during work is used will be broken in too early wearing and tearing; When it breaks, will cause a watt line paper feeding pressure inequality, carry not steadily, cardboard is skidded or result in blockage, even can be parked in the phenomenon of transverse cutting unit front, so the maximum time desired value (being its serviceable life) that sun gear can bear be very crucial.In the prior art, do not carried out the device of fast detecting watt line sun gear life-span, to avoid when reality is used, causing industrial accident.
Summary of the invention:
The purpose of this utility model is to provide a kind of watt device of line sun gear life test that is used for, and the described this watt device of line sun gear life test that is used for will solve prior art and can not test watt technical matters in line sun gear life-span fast.
This watt device of line sun gear life test that is used for of the present utility model, by frame, servomotor, electric machine support, the upward pressure roll shaft, downforce roll shaft and rollers constitute, wherein, described electric machine support is arranged on the described frame, described servomotor is arranged on the electric machine support, described rollers is arranged on the frame, described upward pressure roll shaft and downforce roll shaft are set in parallel on the rollers, be provided with the downforce roller by bearing on the downforce roll shaft, the output shaft of servomotor is connected with a speed reduction unit, the output shaft of described speed reduction unit is connected with the upward pressure roll shaft, and it axially is provided with a friction blend stop described downforce roller upper edge.
Further, described frame is provided with a protective cover, and described protective cover is positioned at the same side of servomotor, upward pressure roll shaft and downforce roller.
Further, be provided with vertical chute in the described rollers, an end of described downforce roll shaft is arranged in the described vertical chute and is fastening by bolt and rollers.
Further, be provided with a photoelectric sensor directly over the top of rollers, the upward pressure roll shaft, the output signal end of described photoelectric sensor is connected with a controller, described controller is arranged in the switch board, the coil of described servomotor is connected with controller, switch board is provided with input media, and described input media is connected with controller.
Further, described servomotor is Lenze's motor.
Principle of work of the present utility model is: sun gear to be measured is fixedly installed on the upward pressure roll shaft, and the output shaft of servomotor and speed reduction unit drives the upward pressure roll shaft and rotates, and the upward pressure roll shaft drives sun gear and rotates together; The downforce roller is by being bolted on the rollers, its up and down rigging position be adjustable, needing to adjust downforce roller surface before the experiment be 0 value with sun gear surface engagement gap, and contact pressure arrives a certain setting value up and down; The friction blend stop of simulation cardboard is fixed on the downforce roller in advance.Owing to the interaction of friction force, sun gear rotates the friction shelves bar that just drives downforce roller and simulation cardboard and rotates simultaneously during running, and the friction blend stop of simulation cardboard is made by metal material.Sun gear is more strict much than the relative evil of the condition of operating mode in the actual motion with the frictional resistance between the downforce roller during motion, because the big manyfold of pressure of its contact pressure real work, the also fast manyfold of speed, passed through the continuous uninterrupted running like this, because of phase mutual friction in its work, need the diffusing a large amount of heat of row, add extraneous temperature, will make rubber components aggravation aging cracking at leisure, forward certain certain revolution to, will wear out and break in the surface of sun gear, be exactly the life-span of its use the limit duration of runs when it breaks.The servomotor coil inside has a stable range of current during operate as normal; variation as its immediate current when the sun gear surface breakdown will exceed its setting range value; thereby realize the motor auto stop, the whole test duration is that life value can be by electrical control cubicles screen displaying and record.
The utility model and prior art are compared, and its effect is actively with tangible.The utility model adopts driven by servomotor sun gear to be measured to rotate, sun gear to be measured is compressed with the pressure roll that has fricting strip contact, simulated solar is taken turns actual working condition, thereby can test out the serviceable life of sun gear, for actual production provides reference, avoid industrial accident.
