Description
Technical field
The utility model belongs to gear drive, particularly relates to a kind of pivoting support and has the transmission device of this pivoting support.
Background technique
Pivoting support mostly is gear transmission, is widely used in the machinery by pivoting support transmission requirement such as hoist, excavator and solar electrical energy generation.The pivoting support of current use is made up of the outer ring with the gear teeth, inner ring, steel ball and spacing block, even circumferential in the raceway between outer ring and inner ring and successively compartment of terrain steel ball and spacing block are installed.The defect existed is pivoting support outer ring is one-piece steel structure, the gear teeth of steel endless screw and outer ring cooperatively interact, when reality uses, the gear teeth are easily engaged with worm screw, cause transmission efficiency low, especially during high speed heavy load, poor work stability, poor reliability, using scope is very limited.
Model utility content
In order to overcome the defect that prior art exists, the purpose of this utility model is to provide the split type pivoting support of a kind of worm gear, solves the problem that is easily engaged with worm screw of the gear teeth, and stable work in work, reliably, transmission efficiency is high.
The split type pivoting support of worm gear, comprise steel outer ring, inner ring, steel ball and spacing block, even circumferential in raceway between outer ring and inner ring and successively compartment of terrain steel ball and spacing block are installed, be characterized in that described outer ring is mounted opposite on the circumferential surface of side and establish ring-shaped step, step is established Cuprum alloy worm gear, the central axis of the central axis of worm gear and inner ring, steel ball on the same line, is fixed on outer ring by Cock screw.
The utility model improves further, and described outer ring step surface is along the central axis place plane symmetry of steel ball, inner ring, and Cock screw is circumferentially all equipped with in the outer, side of step surface.
The utility model improves further, and the thickness of described worm gear is determined according to the distance of worm screw and step surface, and inner ring surface is close to step surface, and the outer ring surface gear teeth match with worm screw.
Another object of the present utility model is to provide a kind of worm and gear pivoting support transmission device, comprise housing, worm screw, cover plate and the split type pivoting support of above-mentioned worm gear, pivoting support is placed in housing and matches with worm screw, pivoting support inner ring is fixed by screw and housing, cover plate buckle closure is on housing, and pivoting support outer ring is fixed by screw and cover plate.
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; Cuprum alloy worm gear is installed in the steel outer ring of this pivoting support, effectively solves the problem that the gear teeth are easily engaged with worm screw, improve transmission efficiency, ensure stability and the reliability of pivoting support transmission operation, can high speed rotary be realized, expand practical ranges.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the sectional view of the split type pivoting support of worm gear;
Fig. 2 is the sectional view of worm and gear pivoting support transmission device.
In figure: 1-worm gear, the 1.1-gear teeth, 2-outer ring, 2.1-step, 3-steel ball, 4-Cock screw, 5-inner ring, 6-worm screw, 7-cover plate, 8-housing.
