Description
Technical field
The utility model relates to pivoting support field, particularly the wheeled pivoting support of a kind of herringbone tooth.
Background technique
Pivoting support (also claiming turntable bearing) is as the important foundation element of engineering machinery and building machinery, except various engineering machinery, the application area of pivoting support is expanding gradually, similar harbour facilities, metallurgical equipment, creeps into the equipment platforms such as platform and has started to use pivoting support to replace original bearing on a large scale.And according to existing technology, the existing pivoting support kind of drive mostly is gear transmission, the high efficiency of its high bearing capacity and transmission, is applied in each large heavy type and light-duty machinery.
Straight-tooth is wheeled, to be that we are daily can see bevel gear type, and herringbone tooth is wheeled just to be used on large power machine.The machine spur gear that transmission force is little, what strength was larger just uses helical gear instead.But along with the development of engineering machinery and building machinery industry, large-scale dynamic power machine gets more and more, becoming increasingly complex of main frame operating mode, especially when transmitting under some need high-speed overload condition, and during the comparatively complicated operating mode of environment, current pivoting support teeth portion structural type can not meet the needs in market day by day.
Summary of the invention
Technical problem to be solved in the utility model is to provide the wheeled pivoting support of herringbone tooth, pivoting support is not only made to operate more steady, be applicable to again the main frame needing high-mechanic transmission simultaneously, the application of pivoting support can be expanded, thus make pivoting support industry obtain the development of diversification.
For achieving the above object, the wheeled pivoting support of the herringbone tooth that the utility model proposes, for the wheeled pivoting support of integrated type Cylinder Gear, it comprises inner ring, outer ring and rolling element, rolling element is arranged in the raceway between inner ring and outer ring, described outer ring is herringbone gear, a part of facewidth is right-hand teeth, and in another part facewidth, is left-hand teeth.
The wheeled pivoting support of described herringbone tooth is the wheeled pivoting support of equiphase herringbone tooth, i.e. centered by the surface of contact of more than helical teeth up and down of outer ring lower helical teeth, axisymmetric is arranged.
The wheeled pivoting support of described herringbone tooth is the not wheeled pivoting support of equiphase herringbone tooth, and namely the helical teeth up and down of outer ring is in people's word arrangement of staggering, and such arrangement makes engagement more smooth-going, only has a small amount of noise that side helical teeth engagement produces in synchronization.On the other hand, staggered due to two row helical teeth, thus add the contact ratio of gear, from Meshing Process of Spur Gear, the engagement of a pair gear teeth can only promote follower and turn over certain angle, gear is operated continuously, just must last engagement is not yet departed to the gear teeth time, rear a pair gear teeth can enter engagement in time.Contact ratio increases, and means that the gear teeth logarithm simultaneously participating in engaging increases, to the generation material impact of gear.With regard to contact ratio, increase its value and can reduce single load to the gear teeth, can reduce the gear teeth engaging-in and nibble out time load impacting, favourable to reduction gear noiose.Secondly, along with the increase of contact teeth number, single driving error to the gear teeth, by homogenizing, can reduce the dynamic exciting of the gear teeth.When pressure angle is identical, if contact ratio increases, teeth bending strength will increase undoubtedly.This be due to contact ratio increase time, the worst point of load in outside i.e. outside monodentate contact points is away from tooth top, and when this some loads, form factor is increase.In high-precision gear transmission, the allowable load of contact strength of tooth surface reduces with the reduction of contact ratio, and in the gear transmission in low precision, maximum Contact Stress of Gear just increases thereupon.And gear improves the method for contact ratio for strengthening the gear number of teeth, lengthening tooth depth, reducing gear spacing, adopt helical gear (helix angle is larger, and contact ratio is larger), etc. method, but these will be restricted, and can not arbitrarily increase.And the not wheeled pivoting support of equiphase herringbone tooth, just by regulating the phase difference between upper and lower two row helical teeth, thus improve the contact ratio of gear parts, transmission is more steady, and noise is less, improves the bearing capacity of pivoting support.Therefore, in the heavy duties such as some Hoisting Machineries, wind power plant, medical military industry equipment, robot or precision type instrument, under equal conditions compare general herringbone gear type pivoting support, adopt the not wheeled pivoting support of equiphase herringbone tooth more can meet complicated main frame working condition requirement, expand the application of pivoting support.
And the selection of the helix angle of herringbone tooth is also had certain requirements:
(1), helixangleβ can not be too small; The contrast of the straight-tooth arrived before and helical teeth, herringbone tooth, exactly in order to prove that herringbone tooth is better than straight-tooth in a lot.If but helix angle is too little, this advantage is just not obvious;
(2), helixangleβ is sure not excessive; Helix angle is too large, not only increases the axial load of supporting, and the slip of the flank of tooth is very violent, and wearing and tearing are very fast, and then cause spot corrosion or gummed, and generally, the supporting bearing so large axial load is also difficult to choose.
Consider several aspects such as the wheeled pivoting support operating conditions of herringbone tooth and manufacture cost, helix angle can be chosen within the scope of this at 15 ° ~ 45 °.
The wheeled pivoting support of herringbone tooth also can be divided into single row type, crossed pin roller type, double-row type and bowling pin combination type according to rolling element structure.The wheeled pivoting support of herringbone tooth has that bearing capacity is high, stable drive and the advantage such as thrust load is little, is widely used in the transmission system of heavy machinery.
Be the position controlling herringbone central plane, the relatively split type positional error greatly reducing herringbone central plane to a certain extent of integrated type by the maximum difficulty of herringbone gear assembling main points known processing herringbone gear, thus meet higher matching requirements.
