主轴箱是机床的重要的部件，是用于布置机床工作主轴及其传动零件和相应的附加机构的。主轴箱是一个复杂的传动部件，包括主轴组件、换向机构、传动机构、制动装置、操纵机构和润滑装置等。其主要作用是支承主轴并使其旋转，实现主轴启动、制动、变速和换向等功能。下面导轨丝杠厂家来讲讲主轴箱主轴制动机构失灵的处理：

The spindle box is an important component of a machine tool, used to arrange the working spindle, its transmission parts, and corresponding additional mechanisms of the machine tool. The spindle box is a complex transmission component, including spindle components, reversing mechanisms, transmission mechanisms, braking devices, control mechanisms, and lubrication devices. Its main function is to support the main shaft and rotate it, achieving functions such as starting, braking, shifting, and reversing the main shaft. The manufacturer of the guide rail screw will explain the handling of the failure of the spindle brake mechanism of the spindle box:

主轴箱采用多级齿轮传动，通过一定的传动系统，经主轴箱内各个位置上的传动齿轮和传动轴，后把运动传到主轴上，使主轴获得规定的转速和方向。主轴箱传动系统的设计，以及主轴箱各部件的加工工艺直接影响机床的性能。

The spindle box adopts multi-stage gear transmission, and through a certain transmission system, the movement is transmitted to the spindle through the transmission gears and shafts at various positions in the spindle box, enabling the spindle to achieve the specified speed and direction. The design of the spindle box transmission system and the processing technology of each component of the spindle box directly affect the performance of the machine tool.

主轴箱位于车床左方的床身上。主轴Ⅵ的回转运动是由电动机输出的恒定转速，通过带轮和各级齿轮的传递实现的，通过主轴箱内滑移齿轮组成不同的传递路线，主轴可获得各级转速。通过操纵机构还可以实现主轴的起动、停止和换向等。

The spindle box is located on the bed to the left of the lathe. The rotational motion of spindle VI is achieved by the constant speed output by the electric motor, transmitted through the pulley and gears at all levels. Different transmission routes are formed by sliding gears inside the spindle box, and the spindle can obtain various levels of speed. By manipulating the mechanism, the spindle can also be started, stopped, and reversed.

1)制动电磁阀产生故障。

1) The brake solenoid valve has malfunctioned.

采取措施：检查电磁铁YT6是否通电吸合，若不通电应检查电气线路；若电磁阀阀芯被卡住，应拆下清洗电磁阀，检查阀芯是否被拉毛或阀孔有毛刺，若有需修光阀芯外圆和阀孔，必须使阀芯在阀孔内滑动灵活无阻滞现象；要求主轴制动时间约为3s.

Measures taken: Check if the electromagnet YT6 is powered on and engaged, and if it is not powered on, check the electrical circuit; If the solenoid valve core is stuck, it should be removed and cleaned. Check if the valve core is roughened or if there are burrs in the valve hole. If there is a need to polish the outer circle of the valve core and the valve hole, it is necessary to make the valve core slide flexibly and without blockage in the valve hole; The spindle braking time is required to be approximately 3 seconds

2)制动摩擦片产生磨损、表面太光滑、太薄或已经碎裂。

2) The brake friction plate is worn, the surface is too smooth, too thin, or has already broken.

采取措施：更换新的摩擦片，并调整使摩擦片之间留有适当间隙。

Measures taken: Replace the friction plates with new ones and adjust them to leave appropriate gaps between them.

3)制动压力太低，摩擦片之间的摩擦力太小。

3) The braking pressure is too low, and the friction between the friction plates is too small.

采取措施：检查压力阀Y一10B的工作压力，根据要求将其压力调0．6MPa。

Measures taken: Check the working pressure of pressure valve Y-10B and adjust its pressure to 0.6MPa as required.

4)主轴箱内润滑油太多，影响摩擦片之间的制动摩擦力。

4) Too much lubricating oil in the spindle box affects the braking friction between the friction plates.

采取措施：调节主轴箱润滑油节流阀，观察主轴箱油标只有少量润滑油滴下即可，若润滑油太多来不及回油，使摩擦片之间存在润滑油，会影响制动摩擦力。

Measures taken: Adjust the lubricating oil throttle valve of the spindle box and observe that only a small amount of lubricating oil drops from the spindle box oil level. If there is too much lubricating oil and there is no time to return it, there will be lubricating oil between the friction plates, which will affect the braking friction force.
