Abstract
A rotation support table for a crane is disclosed, which comprises a gear ring, a rotary disc, a rotary table and a drive gear, wherein the rotary table is fixed together with the rotary disc; the drive gear with a transmission structure fixed on the rotary table is meshed with the gear teeth of the gear ring; a bottom plate is further provided; a circle of convex rings of the rotary disc is located in a ditch formed by the expanding hole of the gear ring and the bottom plate; a circle of rolling balls is arranged between the upper and lower surfaces of the convex rings of the rotary disc and the inner end surface of the expanding hole of the gear ring as well as the upper surface of the bottom plate respectively; the gear ring is fixed with the bottom plate and a frame via bolts uniformly distributed in a circumferential direction; a plurality of superposed gaskets are lined between the butt-joint surfaces of the gear ring and the bottom plate; and the gaskets are sleeved on the bolts. The rotation support table for a crane disclosed by the utility model can conveniently eliminate the gap of the rotary disc, thereby prolonging the service life of the rotary disc and reducing the cost paid by a user; and the rotation support table for a crane is convenient to maintain.
Description
Technical field
The utility model relates to a kind of crane revolution brace table, is used for the rotation of crane bench board.
Background technology
Original crane revolution brace table, what always use is the synthetic rotating disk of one, after turntable clearance exceeds standard, keeps in repair the adjustment chance, service life, weak point was very big waste for the user.
Summary of the invention
The purpose of the utility model provides a kind of crane revolution brace table, solves the defective that can not keep in repair after original crane revolution brace table turntable clearance exceeds standard.
The purpose of the utility model realizes as follows: this crane revolution brace table comprises gear ring, rotating disk, turntable and driven wheel; Turntable and rotating disk are fixed together; Be fixed on the tooth mesh of the driven wheel and the gear ring of the drive mechanism on the turntable; Other has a base plate, and all bulge loops of rotating disk are in the groove that gear ring hole enlargement hole and base plate form, the top and bottom of rotating disk bulge loop and gear ring hole enlargement hole inner end surface and above the base plate between arrange all balls respectively; Bolt through circumferentially being uniformly distributed with between gear ring and base plate and the vehicle frame is lined with some pads of stack between gear ring and the base plate interface, pad is enclosed within on the bolt.The characteristics of the utility model are to be convenient to dismounting, after period of service has been grown rotating disk and the gap occurred, can unclamp bolt and extract pad adjustment, have prolonged the service life of rotating disk.
The utility model can conveniently be eliminated turntable clearance, has prolonged the service life of rotating disk, has reduced the cost that the user pays, and is convenient to maintenance.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
With reference to accompanying drawing; This crane revolution brace table comprises gear ring 1, rotating disk 3, turntable 2 and driven wheel 4; Turntable 2 is fixed together with rotating disk 3, is fixed on the tooth mesh of driven wheel 4 with the gear ring 1 of the drive mechanism on the turntable 2, and other has a base plate 6; One all bulge loops of rotating disk 3 are in the groove that gear ring 1 hole enlargement hole and base plate 6 form, and arrange all balls 5 respectively between the top and bottom of rotating disk 3 bulge loops and gear ring 1 hole enlargement hole inner end surface and base plate 6 are top; Bolt through circumferentially being uniformly distributed with between gear ring 1 and base plate 6 and the vehicle frame 8 is lined with some pads 7 of stack between gear ring 1 and base plate 6 interfaces, pad 7 is enclosed within on the bolt, can eliminate the gap between rotating disk 3 and gear ring 1, the base plate 6 through reducing pad 7.
