The revolving mechanism consists of a revolving support, a revolving platform and a revolving driving device, wherein the revolving support is arranged on a plane; the revolving platform is arranged on the revolving support; the revolving support is connected with the revolving platform through a bolt; the outer ring of the revolving support is provided with a gear ring; the revolving driving device consists of a variable frequency motor, a planetary reducer and a pinion; and the pinion is meshed with the gear ring. The revolving mechanism has the advantages of reasonable and simple structural design and convenience in installation, maintenance and repair.
Description
Technical field
The utility model relates to a kind of slew gear, is applicable to be installed on excavator, crane and so on the engineering machinery.
Background technology
For making equipment in 360 degree, carry out operation on any direction, so slew gear all is being installed on excavator and crane.And existing slew gear structure more complicated, installation, modification maintenance and repair is all cumbersome.Existing excavator peculiar to vessel adopts roller jacket type slewing supporting device more, and this device dismounting is inconvenient, is unfavorable for maintenance, because it is a ring gear mechanism, this structure is also brought very big difficulty to maintenance again.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reasonable in design, simple, and installation, maintenance, repair are slew gear easily.
It is this slew gear that the utility model solves the problems of the technologies described above the technical scheme that is adopted, its design feature is: be made up of revolution support, revolving dial and device for revolving and driving, described revolution is supported and is provided with in the plane, described revolving dial is arranged on revolution and supports, revolution is supported and is connected with the revolving dial bolt, described revolution is supported the outer ring and is provided with gear ring, and described device for revolving and driving is made up of adjustable frequency motor, planetary reduction gear, pinion, and described pinion is meshed with gear ring.
Planetary reduction gear described in the utility model is provided with block.
Planetary reduction gear described in the utility model is provided with rotating angle measurement apparatus.
The utility model is compared with prior art and is had the following advantages and effect: realized that equipment can carry out operation on any direction in 360 degree; Traditional slewing equipment, revolution support and mostly are ring gear, and this structure is installed inconvenient and is unfavorable for safeguarding.With respect to traditional structure, this slew gear has simple in structure, and is easy for installation, safeguards advantage easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is a perspective view of the present utility model.
Label declaration: block 1, device for revolving and driving 2, rotating angle measurement apparatus 3, projection 4, revolving dial 5, adjustable frequency motor 6, planetary reduction gear 7, pinion 8, revolution support 9, the centre of gyration 10, gear ring 11.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figures 1 to 3, present embodiment is made up of revolving dial 5, revolution support 9, device for revolving and driving 2, and device for revolving and driving 2 is made up of adjustable frequency motor 6, planetary reduction gear 7, pinion 8.Planetary reduction box is fixed on the revolving dial 5 by block 1, and block 1 plays positioning tooth roller box position with joining weldering.Revolving dial 5 and revolution are supported 9 and are connected by bolt, and there is gear ring 11 outer ring of revolution support 9.Adjustable frequency motor 6 links to each other with planetary reduction gear 7, and the output of planetary reduction gear 7 is connected with pinion 8, and pinion 8 is meshed with gear ring 11.Revolution is a revolving dial 5 above supporting 9.Planetary reduction gear 7 is installed on the revolving dial 5, and its output shaft is towards vertical with revolving dial 5 downwards.Revolving dial 5 is up and down to there being eccentric orfice.Planetary reduction gear 7 output shafts stretch out by this hole.During work, drive planetary reduction gear 7 by adjustable frequency motor 6 and rotate, support 5 rotations of 9 outer rings drive revolving dial with revolution thereby drive pinion 8.Because equipment is installed on the revolving dial 5, is driven the rotation of equipment by the rotation of revolving dial 5.Thereby realized that equipment can carry out operation on any direction in 360 degree.Compare with traditional slew gear, this utility model has simple in structure, and is easy for installation, safeguards advantage easy to maintenance.
In addition, need to prove, the specific embodiment described in this manual, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
