Description
Technical field:
The utility model relates to a kind of slew gear, and this mechanism can be applicable to the rotating occasion of various needs, as is applicable to the revolution of fire monitor barrel.
Background technology:
At present, various slew gears are more, but the fire monitor of using for fire-fighting fire extinguishing, its slew gear has specific requirement, and such as good airproof performance, volume is little to wait requirement, just present slew gear is often reasonable not because of design, can run into variety of issue during use.
Summary of the invention:
The utility model has designed a kind of slew gear, and this mechanism design is reasonable, compact conformation, and revolution is flexibly.
The purpose of this utility model realizes by following measures:
A kind of slew gear, this mechanism is provided with worm-and-wheel gear, and this slew gear is provided with inside and outside cover and case, and overcoat and upper main body are connected, inner sleeve and lower main body are connected, inside and outside cover assembles mutually, and the worm gear set of described worm-and-wheel gear is contained in the outer ring of overcoat, and this worm gear and overcoat connect as one, the internal perisporium of this worm gear also cooperates by steel ball with inner sleeve, this slew gear is located in the described case, and this case and upper main body are connected, and described worm screw is installed on the case.
Further design of the present utility model is:
Described worm screw two ends are supported in the case 11 by bearing block.
Described inner sleeve outer ring sleeve has a mold insert, and inner sleeve cooperates with the worm gear internal perisporium by this mold insert, and described steel ball is located between mold insert and the worm gear.
The input of worm screw links to each other with CD-ROM drive motor.
Described inside and outside cover mating surface is provided with sealing ring.
Described case one side and upper main body are connected, and opposite side and overcoat cooperation place are provided with sealing ring.
The junction of inner sleeve, case and upper main body also is provided with sealing ring.
The utility model has following advantage compared to existing technology:
The utility model adopts worm gear structure, has designed a kind of slew gear, and this slew gear is provided with inside and outside cover and case, and each several part cooperates closely, and compact conformation designs ingeniously, and favorable sealing property is applicable to multiple revolution occasion.
Slew gear of the present utility model though adopt worm-and-wheel gear, improves it, has saved the rotating shaft of worm gear.Be roll structure between worm gear inner surface and the inner sleeve in the utility model, be equivalent to thus form bearing arrangement, worm gear is equivalent to the outer back-up ring of bearing, thereby is convenient to revolution, also simplifies the structure.
Slew gear of the present utility model improves worm-and-wheel gear, and structural design is compacter, and it is little to take up room, and is suitable for the slew gear of multiple occasion.
Description of drawings
The structural representation of Fig. 1 the utility model slew gear.
Fig. 2 the utility model worm screw part analyse and observe diagram.
Among the figure: the 1-inner sleeve; The 2-overcoat; The 3-case; The 4-worm gear; The 5-worm screw; 501-worm screw input; The 6-mold insert; The 7-steel ball; The upper main body of 8-; Main body under the 9-; The 10-bearing; The 101-sealing ring; The 102-sealing ring; The 103-sealing ring; The 104-sealing ring; The 105-sealing ring.
The specific embodiment
Embodiment one:
Slew gear of the present utility model as shown in Figure 1 and Figure 2, this slew gear is provided with worm-and-wheel gear, this slew gear is provided with inside and outside cover and case, overcoat 2 is connected with upper main body 8, inner sleeve 1 is connected with lower main body 9, inside and outside cover assembles (part is suit mutually) mutually, and the worm gear 4 of worm-and-wheel gear is sleeved on overcoat 2 outer rings and adaptive with it, and this worm gear 4 connects as one with overcoat 2.Inner sleeve 1 outer ring sleeve has a mold insert 6, and this mold insert 6 is fixed with one with inner sleeve 1, and this mold insert 6 is annular solid.Inner sleeve 1 cooperates with worm gear 4 internal perisporiums by this mold insert, and is provided with steel ball between mold insert 6 and worm gear 4.Be equivalent to form a bearing arrangement between worm gear 4 and the inner sleeve 1, thus the frictional force when having reduced revolution, and make this cover mechanism structure compacter, organic becoming one.
This slew gear is located in the case 3, and mainly to play sealing function, this case 3 is connected with upper main body 8 case 3, and worm screw 5 is installed on the case 1.The two ends of worm screw 5 are supported in the case 3 by bearing block, and worm screw input 501 links to each other with CD-ROM drive motor and 4 adopts the spheroidal graphite cast-iron materials.
The course of work:
During the utility model revolution, CD-ROM drive motor drives worm screw and rotates, the worm drive worm gear, because worm gear and lower main body are connected, and are motionless, so worm screw is rotated around worm gear, simultaneously worm screw also drives case, inner sleeve, mold insert and turns round together, thereby realizes the rotation of upper main body.Internus ball bearing structure between mold insert and the worm gear, inner sleeve cooperate with overcoat and are bottom only, and at mating surface sealing ring are housed, and the steel ball between worm gear and the mold insert is conducive to smooth and easy, the neatly revolution of main body.
The utility model not only is provided with sealing ring at inside and outside cover mating surface.Case one side and upper main body are connected, and opposite side cooperates with overcoat also locates to be provided with sealing ring.The junction of inner sleeve, case and upper main body also is provided with sealing ring, has guaranteed being sealed and matched of this slew gear, prevents from revealing in the turning course.
Embodiment two:
This slew gear can be used for the revolution of the barrel of fire monitor, and upper main body is the big gun body, and lower main body is lower big gun body.This slew gear can be used for adjusting big gun head spray angle.
