Abstract
A kind of walking mechanism of DC power supply gas welding-cutting machine, comprise the shell of a DC power supply gas welding-cutting machine, shell is cylinder, the lower end of shell is provided with axletree by bearing, the two ends of axletree are provided with wheel separately, a DC planetary variable speed electric motors, particularly is coaxially arranged with in shell, gap is provided with between the outside of DC planetary variable speed electric motors, particularly and the inner side of shell, the output shaft of DC planetary variable speed electric motors, particularly is coaxially arranged with worm screw, axletree is provided with worm gear, and worm and wheel engages.The utility model utilizes the direct outputting power of DC planetary variable speed electric motors, particularly, simple and compact for structure, overall volume is little, DC planetary variable speed electric motors, particularly and outer casing inner wall have a circle air barrier, the flame high temperature of shell cannot be transmitted to DC planetary variable speed electric motors, particularly, substantially increases system security reliability, and power is directly exported by DC planetary variable speed electric motors, particularly output shaft, decrease the accumulated error of motor vibrations error, speed change error and output error, substantially increase precision.
Description
Technical field:
The utility model relates to mechanical field, particularly relates to the frame for movement of gas welding-cutting machine, and particularly a kind of DC power supply shell is the walking mechanism of cylinder gas welding-cutting machine.
Background technology:
In prior art, portion gas welding-cutting machine adopts battery-powered, to adapt to the restriction of using area, in gas welding-cutting machine, be provided with again the walking mechanism be made up of motor, gear-shift mechanism and wheel, gas welding-cutting machine can be run along certain machining locus.But gear-shift mechanism is directly installed on the housing of gas welding-cutting machine, flame high temperature can be directly transferred on gear-shift mechanism, causes gear-shift mechanism and motor damage.
Summary of the invention:
The purpose of this utility model is the walking mechanism providing a kind of DC power supply gas welding-cutting machine, and the walking mechanism of described this DC power supply gas welding-cutting machine will to solve in prior art gas welding-cutting machine walking mechanism middle gear speed changer easily by the technical problem of flame high temperature failure.
The walking mechanism of this DC power supply gas welding-cutting machine of the present utility model, comprise the shell of a DC power supply gas welding-cutting machine, described shell is cylinder, the lower end of shell is provided with an axletree by bearing, described axletree is parallel to the radial direction of shell, the two ends of axletree are provided with a wheel separately, wherein, a DC planetary variable speed electric motors, particularly is coaxially arranged with in described shell, perpendicular to axial directionly in shell be fixedly installed a dividing plate, described DC planetary variable speed electric motors, particularly is fixedly connected with described dividing plate, gap is provided with between the outside of DC planetary variable speed electric motors, particularly and the inner side of shell, the output shaft of DC planetary variable speed electric motors, particularly is coaxially arranged with worm screw, described axletree is provided with worm gear, described worm screw engages with described worm gear.
Operation principle of the present utility model is: utilize the direct outputting power of DC planetary variable speed electric motors, particularly, gear-shift mechanism need not be set separately, DC planetary variable speed electric motors, particularly and outer casing inner wall have a circle air barrier, make the flame high temperature of shell cannot be transmitted to DC planetary variable speed electric motors, particularly, substantially increase system security reliability.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model arranges DC planetary variable speed electric motors, particularly in the shell of DC power supply gas welding-cutting machine, utilize the direct outputting power of DC planetary variable speed electric motors, particularly, gear-shift mechanism need not be set separately, simple and compact for structure, overall volume is little, form small-sized low speed power system, DC planetary variable speed electric motors, particularly and outer casing inner wall have a circle air barrier, make the flame high temperature of shell cannot be transmitted to DC planetary variable speed electric motors, particularly, substantially increase system security reliability, power is directly exported by DC planetary variable speed electric motors, particularly output shaft, decrease motor vibrations error, the accumulated error of speed change error and output error, substantially increase cutting accuracy.The utility model precision is high, and the life-span is long, easy to maintenance, lightweight.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the walking mechanism of DC power supply gas welding-cutting machine of the present utility model.
Detailed description of the invention:
Embodiment 1:
As shown in Figure 1, the walking mechanism of DC power supply gas welding-cutting machine of the present utility model, comprise the shell 1 of a DC power supply gas welding-cutting machine, described shell 1 is in cylinder, the lower end of shell 1 is provided with an axletree 2 by bearing, described axletree 2 is parallel to the radial direction of shell 1, the two ends of axletree 2 are provided with a wheel 3 separately, wherein, a DC planetary variable speed electric motors, particularly 4 is coaxially arranged with in described shell 1, perpendicular to axial directionly in shell 1 be fixedly installed a dividing plate 7, described DC planetary variable speed electric motors, particularly 4 is fixedly connected with described dividing plate 7, gap is provided with between the outside of DC planetary variable speed electric motors, particularly 4 and the inner side of shell 1, the output shaft of DC planetary variable speed electric motors, particularly 4 is coaxially arranged with worm screw 5, described axletree 2 is provided with worm gear 6, described worm screw 5 engages with described worm gear 6.
The operation principle of the present embodiment is: utilize DC planetary variable speed electric motors, particularly 4 directly outputting power, gear-shift mechanism need not be set separately, DC planetary variable speed electric motors, particularly 4 and shell 1 inwall have a circle air barrier, make the flame high temperature of shell 1 cannot be transmitted to DC planetary variable speed electric motors, particularly 4, substantially increase system security reliability.
