Abstract
A kind of horizontal machine main shaft support mechanism, comprise drive end axle bearing sleeve, non-driven-end bearing cover, single row roller bearing, deep groove ball bearing, the drive end of main shaft is provided with single row roller bearing, deep groove ball bearing and drive end axle bearing sleeve, bearing end cover, internal bearing cover are secured by bolts in drive end bearing and put, the anti-drive end of main shaft is provided with single row roller bearing, bearing holder (housing, cover), and bearing end cover, internal bearing cover are secured by bolts on bearing holder (housing, cover).Horizontal machine main shaft support mechanism of the present utility model, is arranged on the drive end of main shaft by the deep groove ball bearing playing axial location effect, because the drive end load of main shaft is greater than anti-drive end, therefore increase the bearing capacity of drive end; And adopting single row roller bearing to replace existing deep groove ball bearing at main shaft anti-drive end, the higher greatly bearing capacity of main shaft, compared with traditional bearing combining structure, has high performance-price ratio, low-loss, bears the features such as radial load is large.
Description
Technical field
The utility model relates to motor device, especially a kind of horizontal machine main shaft support mechanism.
Background technology
In existing horizontal machine main shaft support mechanism, the drive end of main shaft generally installs a single row roller bearing, main shaft anti-drive end installs a deep groove ball bearing, single row roller bearing mainly carries the radial load of main shaft, and the main use playing axial location of deep groove ball bearing, it is little that radial capacity bears in the main shaft support mechanism of this structure, and merit loss is large.
Summary of the invention
The purpose of this utility model is just to provide a kind of under the condition of equal radial cultivation lotus, and cost performance is high, loss is low, bear the large horizontal machine main shaft support mechanism of radial load.
Horizontal machine main shaft support mechanism of the present utility model, comprise drive end axle bearing sleeve, non-driven-end bearing cover, single row roller bearing, deep groove ball bearing, it is characterized in that, the drive end of main shaft is provided with drive end single row roller bearing, deep groove ball bearing and drive end axle bearing sleeve, outer ring and the drive end axle bearing sleeve of drive end single row roller bearing adopt interference fits, its inner ring and main shaft adopt interference fit, outer ring and the drive end axle bearing sleeve of deep groove ball bearing adopt matched in clearance, inner ring and main shaft adopt interference fit, drive end bearing enclosing cover, drive end bearing inner cap is secured by bolts in drive end bearing and puts, drive end axle bearing sleeve is bolted on drive end end cap.The anti-drive end of main shaft is provided with anti-drive end single row roller bearing, non-driven-end bearing cover, the outer ring of anti-drive end single row roller bearing and non-driven-end bearing overlap and adopt interference fits, its inner ring and main shaft adopt interference fit, non-driven-end bearing enclosing cover, non-driven-end bearing inner cap are secured by bolts in non-driven-end bearing and put, and non-driven-end bearing cover is bolted on non-drive end shield.
Horizontal machine main shaft support mechanism of the present utility model, is arranged on the drive end of main shaft by the deep groove ball bearing playing axial location effect, because the drive end load of main shaft is greater than anti-drive end, therefore increase the bearing capacity of drive end; And adopting single row roller bearing to replace existing deep groove ball bearing at main shaft anti-drive end, the higher greatly bearing capacity of main shaft, compared with traditional bearing combining structure, has high performance-price ratio, low-loss, bears the features such as radial load is large.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
