Description
Technical field
The present invention relates to pivoting support, especially a kind of slip pivoting support that is applicable to large size bearing.
Background technique
Pivoting support is claimed turntable bearing or extra large size bearing again; Be the new machine parts that worldwide grew up gradually in nearly 40 years along with Development in Machine Industry; It is need do relative rotation motion between all two-part, need bear the mechanical necessary important force transfer element of radial load, thrust load and tilting moment again simultaneously.Along with developing rapidly of main frame industry, pivoting support has obtained using widely.Except that be excavator, tower crane, mobile crane and all kinds of hoist supporting; Also be widely used in mechanical fields such as light industry and machinery, metallurgical machinery, medical machinery, industrial robot, rock tunnel(ling) machine, stacker-reclaimer, missile launcher, radar antenna base, revolving stage, the title in " joint of machine " is arranged.
At present the pivoting support produced of China adopts on structural type and is similar to rolling bearing rolling element-rollaway type structure, and its structural type mainly contains four kinds of single-row ball types, single decussation roller formula, double ball formula, three organ timbering formulas.The rolling revolving supporting mainly is made up of rolling element, inner ring and external toothing.Inner ring and external toothing are separately fixed on revolving dial and the rotary case by high-strength bolt.In actual use, thrust load and the radial load of pivoting support except bearing continuous variation also will bear external agency simultaneously like the pollution of rainwater, sand, salt, mud etc.Because ball, roller contact with line with contacting to point contacts of raceway; The poor-performing of its shock resistance anti-vibration, so the tired spot corrosion of raceway often appears in rolling revolving supporting, the rolling element card is stung or the early failure phenomenas such as burn into wearing and tearing that cause because of external agency.In construction machinery industry, because of rolling revolving bearing device manufacturing process is complicated, cost an arm and a leg, change reasons such as difficult in maintenance, pivoting support early failue has become to influence the principal element in engineer equipment life-span.The operational reliability and the fatigue life of how to improve pivoting support are related domain research urgent problems.
Summary of the invention
Technical problem: the objective of the invention is to overcome the deficiency in the prior art, provide that a kind of bearing capacity is high, the antidumping moment capacity is strong, manufacturing process simple, it is lubricated to need not and maintenance, slip pivoting support that cost is low.
Technological scheme: slip pivoting support of the present invention; Comprise following convex rotating disk, be located at down the top rotary table on the convex rotating disk; Be provided with the connecting bolt that connects to one between top rotary table and the following convex rotating disk; The middle part of following convex rotating disk and top rotary table is provided with central through bore; Be provided with rotating disk in the formed annular groove between following convex rotating disk and the top rotary table; Have a plurality of blind holes that are threaded on the exterior edge face circumference of top rotary table and following convex rotating disk, have a plurality of installation through holes on the excircle of rotating disk.
Described convex rotating disk down and top rotary table are made of metal, and the rotating disk that is located between metal convex rotating disk down and the top rotary table is respectively equipped with wear-resisting drip ring and following wear-resisting drip ring in two ends up and down; Described convex rotating disk down and top rotary table are processed by composite material; Described rotating disk is disk or fluted disc; The described chassis of convex rotating disk down is disk or fluted disc.
Beneficial effect: the present invention utilizes the lower rotary table mounting hole that the slip pivoting support is fixed on the equipment rack; Top rotary table is connected revolution part and drive unit respectively with following convex rotating disk; Employing has the composite material of low coefficient of friction and high wear resistance, need not to add lubricant oil.When drive unit rotates, drive convex rotating disk and top rotary table rotation down, thereby make the revolution part rotation.Slip pivoting support processing and assembling is simple, has saved processing, the heat treatment process of raceway, rolling element in the rolling bearing, and processing cost is low.In rotation process, wear-resisting drip ring bearing capacity is big, and the friction factor between the rotating disk is low, need not lubricated and maintenance, has reduced user cost.Needing can be used for pharmacy, food machinery and precision measurement apparatus and the ultrasonic vibration friction welding apparatuses under the bad working environments, the wind electricity generating system of clean environment to transfer to wind system.This slip pivoting support area of contact supports much larger than rolling revolving, and the bearing capacity of slip pivoting support is high
,Have higher load-carrying properties and antidumping moment, wear-resisting drip ring has self-lubricating property, so need not lubricated in the using process and maintenance, has reduced user cost.
