Abstract
The utility model discloses a driving slewing bearing of a plane enveloping worm wheel. The driving slewing bearing comprises a worm wheel outer ring, a worm wheel inner ring, a taper pin, a plug, a steel ball, an isolation block, an oil nozzle and a sealing strip, wherein the outer periphery of the worm wheel outer ring is provided with an outer annular arc groove; a through hole is formed in a plane perpendicular to the outer periphery of the outer ring, the through hole is internally provided with the oil nozzle, and the outer periphery of the inner ring is provided with an outer annular arc groove, the inner periphery of the outer ring is provided with an inner annular arc groove, and the inner annular arc groove and the outer annular arc groove are mutually matched to form a raceway for enabling a ball to operate; the inner ring is provided with a pin hole and a blocking hole, the plug is provided with a through hole which is perpendicular to the pin hole, and the taper pin is inserted into the pin hole to fix the plug. The driving slewing bearing provided by the utility model has the advantages that the transmission efficiency and the carrying capacity are improved, the vibration and noises are reduced in operation, the manufacture is easy, and the accurate machining and quenching grinding completely conforming to a meshing principle are easy to realize.
Description
Technical field
The utility model relates to the structure-design technique field of pivoting support, is specially a kind of planar envelope worm drive pivoting support.
Background technique
Pivoting support is used widely in real industry, by people, be called " joint of machine ", between two articles, to need to do relative rotation motion, need again to bear the necessary important transmission part of machinery of axial force, radial force, tilting moment simultaneously, have compact structure, motion steadily, the feature such as precision is high and bearing capacity is strong.Except various engineering machinery, the application area of pivoting support expands at present gradually, as the equipment such as harbour facilities, metallurgical equipment, drill platform have started to use pivoting support to replace original bearing on a large scale.
Common cylinder Worm Wheel System transmission efficiency is lower, weares and teares more serious, and when its engagement driving, the relative sliding velocity of meshing wheel between cog is large, therefore frictional loss is large, efficiency is low, relative sliding velocity conference makes flank of tooth heavy wear, heating.Because this transmission is sliding friction transmission, meeting in service produces more heat, makes thermal expansion between each part of pivoting support and sealing produce difference, thereby forms gap at each fitting surface; Lubricating oil, because the rising of temperature is thinning, easily causes leakage, worm gear wearing and tearing.
Model utility content
The purpose of this utility model is to provide a kind of planar envelope worm drive pivoting support, to solve cylinder worm gear in prior art, is difficult for the problems such as grinding, transmission efficiency is low, tooth surface abrasion is very fast, load is relatively little.
In order to address the above problem, the technological scheme that the utility model adopts is:
A kind of planar envelope worm drive pivoting support, include worm-gear type outer ring, inner ring, taper pin, stop up, steel ball, spacing block, oil nozzle and Stamping Steel Ribbon, it is characterized in that: described worm-gear type outer ring outer circumferential face is provided with outer ring arc groove, in the plane vertical with outer ring outer circumferential face, have through hole, oil nozzle is housed in through hole, the outer circumferential face of described inner ring offers outer ring arc groove, the inner peripheral surface of outer ring offers interior annular arc groove, interior annular arc groove and outer ring arc groove cooperatively interact and form the raceway for ball operation, on inner ring, have pin-and-hole and plugging hole, obstruction is provided with the through hole vertical with pin-and-hole, taper pin inserts fixing obstruction in pin-and-hole.
Described a kind of planar envelope worm drive pivoting support, is characterized in that: described steel ball and spacing block are packed into and in raceway, are connected inner ring and outer ring by plugging hole.
Described a kind of planar envelope worm drive pivoting support, is characterized in that: the raceway above and below between described inner ring and outer ring is provided with seal groove, and Stamping Steel Ribbon is housed in seal groove.
Described a kind of planar envelope worm drive pivoting support, is characterized in that: the material of described inner ring and outer ring is 42CrMo.
Advantage of the present utility model:
Planar double enveloping turbine and worm pair is to take the flank of tooth that a plane goes out toroid helicoids worm as generatrix by relative circular movement envelope to take the flank of tooth of worm screw again and by relative movement envelope, go out the flank of tooth of worm gear as generatrix.With respect to common worm couple, planar double enveloping worm couple is that a kind of novel rotary driving form and its are that multiple tooth contact contacts with two Line of contact, the Precise Grinding after cure process of the flank of tooth of turbine forms, and tooth face hardness surface table rugosity grade improves can reach very high flute profile precision.Planar double enveloping worm drive pivoting support is a kind of advanced person's heavily carrying transmission device, when toroid helicoids worm with matching carries out engagement driving, by expanding area of contact, improve oil film formation condition, the Relative radius of curvature that increases between the flank of tooth improves transmission efficiency and bearing capacity, bearing capacity is stronger; More easily form oil and contain, lubricated more abundant, there is higher efficiency.Planar envelope worm drive pivoting support is easy to manufacture, more easily realizes and meets the accurate processing of its theory of engagement and the grinding of hardening completely.
