Description
Technical field
The utility model belongs to pivoting support, particularly a kind of straight-tooth end-tooth pivoting support.
Background technique
Pivoting support is a kind of large size bearing that can bear combined load, can bear larger axial, radial load and tilting moment simultaneously.
Pivoting support is turntable bearing again, and some people is also called: swivel bearing, convolution supporting.Pivoting support is applied very extensive in real industry, and being called by people: " joint of machine ", is need between two articles to do relative rotation motion, needs again the necessary important transmission part of machinery simultaneously bearing axial force, radial force, tilting moment.Along with developing rapidly of machinery industry, pivoting support is widely used in industries such as ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial machineries.
The centering that pivoting support generally realizes pivoting support and associated part by positioning spigot and bolt is installed and moment transmission.The field used along with pivoting support constantly expands, engineering machinery tonnage is also increasing, existing pivoting support centering installation and moment transfer mode can not meet the demand of industry high speed development, particularly large-tonnage associated part and pivoting support centering install extremely inconvenience, centering can expend operator's plenty of time, and by bolt axis to tightening force carry-over moment, easily cause stress to concentrate, bolt failure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of straight-tooth end-tooth pivoting support, realize pivoting support and large-tonnage associated part self contering centering is installed and the transmission of larger torque, avoid stress to concentrate causing the generation of bolt failure phenomenon, simultaneously, little to original pivoting support structural modification, easily industrially realize, there is certain application value.
For achieving the above object, a kind of straight-tooth end-tooth of the utility model pivoting support, it comprises outer ring, inner ring, blocking, taper pin, Stamping Steel Ribbon, roller, spacing block and oil nozzle, it is outer interior formula structure between described outer ring and inner ring, namely outer ring is positioned at the outside of inner ring, and form raceway in the middle part of described outer ring and inner ring, between outer ring and inner ring, joint is sealed by Stamping Steel Ribbon, prevent entering of dust foreign material, the lubricating grease between roller can be preserved.Roller and spacing block are arranged in raceway, in the middle part of outer ring, have the hydraulic fluid port be connected with raceway, described oil nozzle is fixedly installed on hydraulic fluid port, can grease up in raceway in the past by oil nozzle, lubrication roller and raceway, it is straight-tooth end-tooth that end face is installed in described outer ring.When pivoting support and large-tonnage associated part are installed, only need sling above pivoting support by large-tonnage associated part, pivoting support and large-tonnage associated part can realize self contering centering, without the need to the artificial centering of actuator after slinging, and the saving installation time; Meanwhile, between this pivoting support and large-tonnage associated part, there is not relative movement, without the need to the effect of bolt, use pivoting support to get final product direct transmitting torque.
The utility model is further improved, and the profile angle of the straight-tooth end-tooth of described pivoting support is 40 ° or 60 °, is optimum, to realize pivoting support and large-tonnage associated part self contering centering more easily with 40 °; Profile angle is the angle of the adjacent flank of tooth between adjacent two teeth of the outer ring installation end face of pivoting support.
The utility model is further improved, and described roller type is single-row ball type or double ball, and spacing block is ball spacing block, can realize the self-alignment of roller.
The utility model structure is simple, easy to use, achieve pivoting support and large-tonnage associated part self contering centering is installed and the transmission of larger torque, avoid stress to concentrate causing the generation of bolt failure phenomenon, simultaneously, little to original pivoting support structural modification, easily industrially realize, there is certain application value.
