求翻译：这种方法是利用50W的电灯泡来加热轴承的，可保证加热的温度在 100℃ 左右，对于较小的轴承可直接放在灯泡上，较大轴承则可置于灯泡的锥形罩内，锥形罩是可防灯泡热量散失的，并使加热非常均匀。锥形罩上下还可以进行调位，在一定的范围之内可以适应于加热不同大小尺寸的轴承。如果是采用的远红外灯泡，要注意灯泡的方向应该向下，以避免红外射线伤害到人的眼睛。这种灯泡是可以节能的。灯泡的加热法适用于数量较少而且不经常要对轴承进行加热的场合，平时情况下灯泡还可用作照明，此外并不需要任何的其他设备。是什么意思？

This method is to use the 50W light bulb to heat the bearing can ensure heating temperatures at around 100 ° c, for smaller bearing directly on the light bulb on larger bearings may be placed within a cone-shaped hood of the bulb, cone-shaped CAP is anti-bulb heat dissipation, and enables very uniform heating. Conical cover can also be adjusted up or down, in a certain range can be adapted to the heating of different sizes of bearings. If you are using far infrared light bulbs, to note the direction of the light bulb should be down, infrared Ray to avoid harm to people's eyes. This energy-saving lamp is. Light bulb of heating applied to fewer and less frequently to heating the bearing of the occasion, usually cases bulbs can also be used as a lighting, and does not need any other equipment.
