Abstract
A plasma rotating electrode powder making device transmission device comprises motors and rollers connected with the motors through couplers. The motors, the couplers and the rollers are arranged into two groups in parallel. A compression roller is arranged above the two groups of rollers, a bar is arranged among the two groups of rollers and the compression roller, and a tip of a material pushing device is inserted into a center hole of the bar. Due to the fact that the bar is arranged among the two groups of rollers arranged horizontally and the compression roller, and the two groups of rollers and the compression roller form three-roller support, the bar can be firmly controlled. The transmission device solves the problem that the bar is unstable under high speed rotating of the existing transmission device. The three-roller support ensures that the bar advances stably under pushing of the material pushing device when the bar rotates at high speed, a plasma gun does not need to move, plasma arc is stable, and generated powder is higher in quality.
Description
Technical field
The utility model relates to a kind of transmission device, is specifically related to a kind of transmission device of plasma rotating electrode powder manufacturing apparatus.
Background technology
Refining metallic powder can adopt aerosolization and plasma rotating electrode method to produce, and the powder good sphericity that plasma rotating electrode method is produced, has important purposes in the superalloy powder field of producing.Due to plasma rotating electrode powder manufacturing apparatus complex structure, at present domestic is substantially all from Russian import, and therefore the further investigation of article on plasma rotation electrode powder manufacturing apparatus has great significance.
Plasma rotating electrode powder manufacturing apparatus is made up of a series of parts that are coupled to each other, device and system, and utilizes vacuum seal that each several part is linked together.Spray chamber, machine driving chamber and charging box are the primary structures of equipment, and the transmission device Main Function in machine driving chamber is bar to be delivered to spray chamber by root melt and make needed powder.The quality of transmission device directly has influence on the height of the product quality of producing by the method.
Because plasma rotating electrode method flouring technology has high requirement to the rotating speed of bar, at present, the moving bars of motor straight tape splicing that adopt rotate more at home, by the bar that moves axially fusing rotation of plasma gun.The defect of design is like this: bar is that one end connects the shaft coupling connecting with motor, changes bar comparatively complicated, and bar is also had to technological requirement, must guarantee to coordinate with shaft coupling.Even like this, bar is extremely unstable under High Rotation Speed, and especially larger away from the amount of deflection of motor side, the design of plasma gun has higher requirement, and the powder quality obtaining neither be very high, and more severe patient is easily accidents caused.
Utility model content
The purpose of this utility model is to provide a kind of transmission device of plasma rotating electrode powder manufacturing apparatus, has solved the not high problem of powder quality that existing transmission device is extremely unstable at the lower bar that runs up and obtain.
The technical scheme that the utility model adopts is, the transmission device of plasma rotating electrode powder manufacturing apparatus, comprise motor and the cylinder being connected by shaft coupling with motor, motor, shaft coupling and cylinder are arranged with two groups in parallel, the top of two series cylinders is provided with hold-down roller, between two series cylinders and hold-down roller, be provided with bar, in the centre bore of the top insertion bar of material-pulling device.
Feature of the present utility model is also,
The bottom of bar contacts with two series cylinders, the top of bar and hold-down roller close contact.
The shaft shoulder place at cylinder two ends is provided with bearing.
The shaft shoulder place at hold-down roller two ends is provided with bearing.
Bearing adopts the water-cooling structure bearing of magnet fluid sealing.
The beneficial effects of the utility model are, the transmission device of the utility model plasma rotating electrode powder manufacturing apparatus, by bar being arranged between two groups of horizontally disposed cylinders and hold-down roller, two series cylinders and hold-down roller form three-roller type to be supported, and can control firmly bar; Solve the transmission device of existing plasma rotating electrode powder manufacturing apparatus under High Rotation Speed, the unsettled shortcoming of bar, three-roller type supports, can guarantee that bar is in the time of High Rotation Speed, bar is stable advancing under the passing of material-pulling device, plasma gun does not need mobile, and plasma arc is more stable, and the powder quality of generation is higher.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The transmission device of the utility model plasma rotating electrode powder manufacturing apparatus, as shown in Figure 1, comprise motor 1 and the cylinder 7 being connected by shaft coupling 2 with motor 1, motor 1, shaft coupling 2 and cylinder 7 are arranged with two groups in parallel, the top of two series cylinders 7 is provided with hold-down roller 4, between two series cylinders 7 and hold-down roller 4, be provided with bar 5, in the centre bore of the top insertion bar 5 of material-pulling device 3, promote bar 5 and move horizontally.
The bottom of bar 5 contacts with two series cylinders 7, the top of bar 5 and hold-down roller 4 close contact, and two series cylinders 7 form three-roller type with hold-down roller 4 to be supported, and can control firmly bar 5.
The shaft shoulder place at cylinder 7 two ends is provided with bearing 6, and the shaft shoulder place at hold-down roller 4 two ends is provided with bearing 6; Due to cylinder 7 high speed rotating, the environment of transmission device work has again dust, therefore bearing 6 is had to particular/special requirement, and bearing 6 of the present invention adopts the water-cooling structure bearing of magnet fluid sealing.
The operation principle of the transmission device of the utility model plasma rotating electrode powder manufacturing apparatus: motor 1 is high-speed electric expreess locomotive, is directly passed to cylinder 7 by the effect of shaft coupling 2 by the speed of motor 1, drives cylinder 7 high speed rotating; Hold-down roller 4 is being pressed bar 5 and cylinder 7 close contacts, and bar 5 forms friction with cylinder 7, and under the drive of frictional force, cylinder 7 is with bar 5 high speed rotating; Meanwhile, material-pulling device 3 promotes bar 5 and moves horizontally, and so far bar 5 can be realized high speed rotating and move horizontally, and transmission effect as shown in Figure 2.
The transmission device of the utility model plasma rotating electrode powder manufacturing apparatus, by bar 5 being arranged between two groups of horizontally disposed cylinders 7 and hold-down roller 4, two series cylinders 7 form three-roller type with hold-down roller 4 to be supported, and can control firmly bar 5; Solve the transmission device of existing plasma rotating electrode powder manufacturing apparatus under High Rotation Speed, the unsettled shortcoming of bar, three-roller type supports, can guarantee that bar is in the time of High Rotation Speed, bar is stable advancing under the passing of material-pulling device 3, plasma gun does not need mobile, and plasma arc is more stable, and the powder quality of generation is higher.
It is selecting of bearing 6 that the utility model is achieved most crucial, adopt the water-cooling structure bearing of magnet fluid sealing, micro powder under equipment working condition can not enter in bearing 6 under magnetic fluid effect, and water-cooling structure can solve the heat that high speed rotary grinding generates simultaneously.
