Abstract
A main bearing device of woodworking machine comprises a bearing body whose two ends are mounted with a bearing, and a main shaft in the bearing body. The utility model is characterized in that a bearing sleeve is mounted outside two ends of the main shaft in the bearing body, a bearing is mounted in the bearing sleeve, and the ends of the bearing and bearing sleeve are mounted with end covers. When in installment, user first installs a bearing in the bearing sleeve, mounts the bearing and bearing sleeve on the main shaft, and mounts the bearing sleeve, bearing and main shaft in the bearing body together, with simple assembly, and when in maintenance or exchange of bearing or main shaft, user only needs to detach the bearing sleeve from the bearing body (the bearing is detached with the bearing sleeve). Compared with the prior art, the utility model has simple production, low production cost, better concentricity, avoided dust, long service life, simple detachment of bearing or the like and easy exchange. The bearing body and the bearing sleeve are fixed via fixing bolts, with firm installment and stable fit with main shaft.
Description
Technical field
The utility model relates to woodworking machine, particularly relates to woodworking machine main bearing device, mainly is applicable to various high speeds Shandong machine, sander and planing machine, belongs to woodworking machinery.
Background technique
Woodworking machinery is extensive use of in furniture making and building, decorative craft, and in recent years, various types of woodworking machine are comparatively fast developed.Woodworking machine mainly be main shaft by bearings on frame, drive running by power transmission belt wheel.The prior art bearing is to be directly installed in two of machine bearing body or abrasive belt wheel, the shortcoming of its existence is that bearing rubs in high speed rotating greatly, be easy to generate distortion, make two concentricity of main shaft poor, rotating speed reduces, and friction ambassador's pellet shot from a slingshot (bearing) can generate heat, and has influenced the working life of bearing; Be that bearing is directly installed in the bearing support on the other hand,,, do not have the accessory transposing, dismantle, keep in repair very difficult in case damage if equipment such as trouble, particularly large-scale milling machine are keeped in repair in bearing or main shaft damage.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of Bearing Installation easy, two good concentricity, dismounting, replacing convenience, spindle speed raising, the woodworking machine main bearing device of bearing long service life.
The technological scheme of the utility model woodworking machine main bearing device is: comprise bearing support, in bearing support two, bearing is installed, main shaft is installed in the bearing support, it is characterized in that installation shaft bearing sleeve outside bearing support inner main axis two, Bearing Installation is installed silently lid at the end face of bearing and bearing housing in bearing housing.
Woodworking machine main bearing device of the present utility model, during installation earlier with Bearing Installation in bearing housing, be installed in bearing and bearing housing on the main shaft together again, put into bearing, bearing housing and main shaft in the bearing support together then, just adopt bearing is installed in the bearing housing, be fixed on bearing support two ends (screw is fastening) again, assemble very convenient, if damage such as bearing or main shaft needs repairing, changes, as long as bearing housing etc. is unloaded (bearing and then unloads) bearing housing in bearing support.Compared with the prior art, this programme machining is convenient, low cost of manufacture, and assembling is rationally, and is indeformable, good concentricity improves rotating speed, avoids dust to invade long service life again, dismounting only damages and need change bearing housing and bearing or main shaft easily, need not change bearing support, need not relate to complete machine.
Woodworking machine main bearing device of the present utility model, its bearing support and bearing housing are fixed by clamping bolt, and it is firm to install, and cooperates more stable with main shaft.Its described bearing is interior each two of every head bearing cover, between two bearings back-up ring is installed.Its described bearing housing can be the eccentric shaft bearing sleeve.
