主軸箱是機床的重要的部件，是用于布置機床工作主軸及其傳動零件和相應的附加機構的。主軸箱是一個復雜的傳動部件，包括主軸組件、換向機構、傳動機構、制動裝置、操縱機構和潤滑裝置等。其主要作用是支承主軸并使其旋轉，實現(xiàn)主軸啟動、制動、變速和換向等功能。下面導軌絲杠廠家來講講主軸箱主軸制動機構失靈的處理：

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:

主軸箱采用多級齒輪傳動，通過一定的傳動系統(tǒng)，經主軸箱內各個位置上的傳動齒輪和傳動軸，后把運動傳到主軸上，使主軸獲得規(guī)定的轉速和方向。主軸箱傳動系統(tǒng)的設計，以及主軸箱各部件的加工工藝直接影響機床的性能。

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.

主軸箱位于車床左方的床身上。主軸Ⅵ的回轉運動是由電動機輸出的恒定轉速，通過帶輪和各級齒輪的傳遞實現(xiàn)的，通過主軸箱內滑移齒輪組成不同的傳遞路線，主軸可獲得各級轉速。通過操縱機構還可以實現(xiàn)主軸的起動、停止和換向等。

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)制動電磁閥產生故障。

1) The brake solenoid valve has malfunctioned.

采取措施：檢查電磁鐵YT6是否通電吸合，若不通電應檢查電氣線路；若電磁閥閥芯被卡住，應拆下清洗電磁閥，檢查閥芯是否被拉毛或閥孔有毛刺，若有需修光閥芯外圓和閥孔，必須使閥芯在閥孔內滑動靈活無阻滯現(xiàn)象；要求主軸制動時間約為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)制動摩擦片產生磨損、表面太光滑、太薄或已經碎裂。

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

采取措施：更換新的摩擦片，并調整使摩擦片之間留有適當間隙。

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

3)制動壓力太低，摩擦片之間的摩擦力太小。

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

采取措施：檢查壓力閥Y一10B的工作壓力，根據要求將其壓力調0．6MPa。

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

4)主軸箱內潤滑油太多，影響摩擦片之間的制動摩擦力。

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

采取措施：調節(jié)主軸箱潤滑油節(jié)流閥，觀察主軸箱油標只有少量潤滑油滴下即可，若潤滑油太多來不及回油，使摩擦片之間存在潤滑油，會影響制動摩擦力。

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.
