Abstract
The invention discloses an overturning moment resisting device for a swing bearing, which is applied to the industry of swing bearings for heading machines. The entire device consists of an upper rotary table, a bearing sleeve, a bearing, a shaft, a frame bottom plate, a swing bearing, a first connecting bolt and a second connecting bolt, wherein the bearing sleeve is welded on the upper rotary table of a heading machine according to the requirement on the outer diameter installation size of a selected bearing capable of bearing a relatively high radial load; the shaft is welded on the frame bottom plate according to the inner diameter installation size of the selected bearing; a spigot coaxial with the bearing sleeve is processed on the installation contact surface between the upper rotary table and the swing bearing according to the requirement on the inner ring installation size of the swing bearing; and a spigot coaxial with the shaft is processed on the installation contact surface between the frame bottom plate and the swing bearing according to the requirement on the outer ring installation size of the swing bearing. The device obtains a larger overturning moment by using the upper rotary table of the heading machine which has the same machine width in combination with the swing bearing and the problem that a heading machine with an overlarge transverse size is not suitable for a working condition is solved. A relatively small swing bearing can be selected when the device is used on the heading machine, so that the transverse size of the heading machine is reduced correspondingly.

Summary of the invention:
The object of the present invention is to provide a kind of device that can cooperate floating bearing to use, the development machine upper turntable that is used identical machine width by this device and floating bearing can obtain larger anti-tilting moment, thereby solve development machine because of the excessive problem that can not be applicable to operating mode of lateral dimension, thereby can select the less floating bearing to make that the development machine lateral dimension is corresponding to be reduced by use this device at development machine, make development machine go for more multi-state, effectively improve the utilization rate of same model development machine.
The object of the present invention is achieved like this: a kind of device of floating bearing overturning or slip resistance analysis moment, whole device is comprised of upper turntable, bearing holder (housing, cover), bearing, axle, framework soleplate, floating bearing, the first connecting bolt, the second connecting bolt, external diameter installation dimension according to the selected bearing that can bear larger radial load on the upper turntable of development machine requires to add the weldering bearing holder (housing, cover), and basis selects the internal diameter installation dimension of bearing to add the weldering axle on framework soleplate; The interior ring installation dimension of with good grounds floating bearing requires to process the seam that the axiality relation is arranged with bearing holder (housing, cover) on the contact surface installing with floating bearing on the upper turntable; The outer shroud installation dimension of with good grounds floating bearing requires to process the seam that the axiality relation is arranged with axle on framework soleplate and floating bearing installation contact surface; The outer shroud installation dimension of with good grounds floating bearing requires to process the seam that the axiality relation is arranged with axle on framework soleplate and floating bearing installation contact surface; External diameter installation dimension according to the bearing of selecting on the development machine upper turntable adds the weldering bearing holder (housing, cover) coaxial with the floating bearing installation site, adds the weldering axle coaxial with the floating bearing installation site according to the internal diameter installation dimension of selecting bearing on framework soleplate; The bearing of selecting is installed in axle, and floating bearing is installed in axle to be had on the framework soleplate of coaxial relation seam, does the location with the bearing outside diameter selected, install with bearing holder (housing, cover) upper turntable welded together on; The axial compression that is directed to floating bearing that produces during cutting part of development machine work passes on the interior ring of floating bearing by upper turntable, the second roller finally passes on the framework soleplate after passing to the outer shroud of floating bearing in floating bearing, so the bearing of installation is owing to adopt end-play not to be subjected to responsive to axial force; The floating bearing tilting moment that is directed to that produces during cutting part of development machine work is delivered on the upper turntable, a part of part tilting moment is passed on the interior ring of floating bearing by the second connecting bolt that is connected with upper turntable, pass to the outer shroud of floating bearing by the first roller in the floating bearing and the second roller, pass on the framework soleplate by the first connecting bolt that is connected with the outer shroud of floating bearing; Part tilting moment passes to bearing by the bearing holder (housing, cover) that welds together with upper turntable, passes to framework soleplate by the bearing warp beam.
Main points of the present invention are its structure and operating principle.Its operating principle is: a kind of device that this device and common floating bearing are used, can obtain larger anti-tilting moment by the floating bearing that installs this device same model additional, after development machine uses, can effectively reduce machine-wide, increase the adaptation condition ability of development machine; The device of floating bearing overturning or slip resistance analysis moment is by increasing the cover bearing arrangement coaxial with the floating bearing installation site at ordinary construction, thereby reaches this device and floating bearing bears overturning moment jointly.
A kind of device of floating bearing overturning or slip resistance analysis moment compared with prior art, have the development machine upper turntable that is used identical machine width by this device and floating bearing and can obtain larger anti-tilting moment, thereby solve development machine because of the excessive problem that can not be applicable to operating mode of lateral dimension, thereby can select the less floating bearing to make that the development machine lateral dimension is corresponding to be reduced by use this device at development machine, make development machine go for more multi-state, effectively improve the advantages such as utilization rate of same model development machine, will be widely used in development machine floating bearing industry.
