托辊轴承的选择

Selection of roller bearing

目前主要使用的是深沟向心球轴承和圆锥滚子轴承。

At present, deep groove centrifugal ball bearings and tapered roller bearings are mainly used.

深沟向心球轴承

Deep groove centripetal ball bearing

特点：①可以做成大游隙，允许州苗木 保定通风管道 丝网立柱模具 尼龙输送带 保定防水 保定空压机 高碑店养老院大的加工安装误差和轴的弯曲变形；②运转阻力略低于圆锥滚子轴承；③价格较低。

Features: (1) it can be made into large clearance, allowing greater machining and mounting errors and bending deformation of the shaft; 2. The running resistance is slightly lower than that of the tapered roller bearing; (3) the price is lower.

主要缺点：①抗冲击能力差；②不能承受较大的轴向力；③抗腐蚀能力差；④使用寿命低于圆锥滚子轴承；⑤在相同的承载能力下尺寸较圆锥滚子轴承大。

Main shortcomings: (1) poor impact resistance; (2) cannot bear large axial force; (3) poor corrosion resistance; (4) service life is lower than tapered roller bearing; 5. The size of the same bearing capacity is larger than that of tapered roller bearing.
