Abstract
The utility model discloses a composite transmission slewing speed reducer of a worm and gear pair and a gear. The composite transmission slewing speed reducer comprises a base (1), wherein a slewing bearing (2) is arranged on the base (1), and a worm (3) is arranged on one side of the base (1). The composite transmission slewing speed reducer is characterized in that a gear shaft (4) is arranged between the worm (3) and the slewing bearing (2), a worm wheel (5) is arranged on the gear shaft (4), the worm wheel (5) is meshed with the worm (3), the slewing bearing (2) comprises an inner ring and an outer ring, and a gear on the gear shaft (4) is meshed with the outer ring of the slewing bearing (2). According to the composite transmission slewing speed reducer of the worm and gear pair and the gear, the structure is compact, installation is convenient to carry out, the worm wheel consumes little copper alloy in manufacturing, manufacturing cost is reduced, high torque can be transmitted, the speed reducing ratio of two-grade transmission is large, and operation is stable at a low rotating speed.
Description
Technical field
The utility model relates to a kind of rotary decelerator, is specially adapted to the engineering machinery transmission fields such as high-altitude operation vehicle, truck-mounted crane, rotation fork truck.
Background technique
At engineering machinery transmission fields such as high-altitude operation vehicle, truck-mounted crane, rotation fork trucks, there are two critical pieces need to do relative rotation motion, junction at two parts, mainly contain at present two kinds of mode of structure: a kind of is that the toothed revolution support in outer ring is meshed with a toothed worm-gear speed reducer, and shortcoming is that structure is loaded down with trivial details, trouble is adjusted in installation; Another kind of structure is that outer ring is the pivoting support retarder of worm couple, although compact structure, easy for installation, but the pivoting support outer ring is the steel part structure, when needs during than high pulling torque Worm Wheel System can produce gummed, if outer ring is used the edge steel structure instead, cost is too high, and only have the one-level transmission, slow down smaller, when the needs output speed is low, oil hydraulic motor also is in than slow-speed of revolution running, and smoothness of operation is poor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of worm couple and gear Composite Transmission rotary decelerator are provided, its compact structure, easy for installation, it is less that the worm gear making expends Cuprum alloy, reduced fabricating cost, can transmit than high pulling torque, the secondary transmission reduction speed ratio is large, smooth running when the slow-speed of revolution.
The purpose of this utility model is achieved in that a kind of worm couple and gear Composite Transmission rotary decelerator, it comprises pedestal, on described pedestal, be provided with pivoting support, described pedestal one side is provided with worm screw, it is characterized in that: between described worm screw and pivoting support, be provided with gear shaft, be provided with worm gear on described gear shaft, described worm gear is meshed with worm screw, described pivoting support comprises inner ring and outer ring, and the gear on described gear shaft is meshed with the outer ring of pivoting support.
Described worm gear comprises worm gear core and worm gear gear ring, and described worm gear gear ring is made by Cuprum alloy.
The whole Cuprum alloy that adopts of described worm gear is made.
Compared with prior art, the utlity model has following beneficial effect:
A kind of worm couple of the utility model and gear Composite Transmission rotary decelerator, its compact structure, easy for installation, it is less that the worm gear making expends Cuprum alloy, reduced fabricating cost, can transmit than high pulling torque, the secondary transmission reduction speed ratio is large, smooth running when the slow-speed of revolution.
