根據(jù)永保機(jī)械裝載機(jī)專家的計(jì)算和分析，小型裝載機(jī)活塞桿彎曲的原因有以下幾點(diǎn)：
1、動(dòng)臂缸兩端與機(jī)架和動(dòng)臂連接有傾斜現(xiàn)象，支承寬度過小
Both ends of the boom cylinder is connected to the frame and boom tilt, bearing width is too small.
2、裝配調(diào)整間隙不當(dāng)，導(dǎo)致側(cè)面磨損嚴(yán)重
Adjust the gap to improper assembly, leading to serious side wear.
3、動(dòng)臂缸下端排料處沉積料積累和動(dòng)臂缸下端外側(cè)磨損
Sedimentary material accumulation and the lower boom cylinder boom cylinder discharge at the lower end of the outer wear.
4、沉積料積累嚴(yán)重，旋轉(zhuǎn)摩擦力較大
Severe accumulation of sedimentary material, large rotary friction.

同時(shí)，永保機(jī)械的專家為大家提供了一下改進(jìn)措施：

1、加大支承寬度，一般支承寬度為活塞桿直徑的1.2～1.5倍。
Increase the bearing width, the width of the support rod diameter generally 1.2 to 1.5 times.
2、在裝配過程中，充分利用調(diào)整墊保證動(dòng)臂缸兩端與機(jī)架和動(dòng)臂的配合間隙與對(duì)中性，提高調(diào)整墊材料耐磨性能。
During assembly, adjustment pad to ensure full use of the boom cylinder with the gap at both ends of the rack and boom with neutral, adjust the pad material to improve wear resistance.
3、改進(jìn)排料結(jié)構(gòu)，增大排料板的開口距離H1和傾斜角度α，減少落料的積存，利于落料順利自然排出；增大動(dòng)臂缸下端與主機(jī)連接處排料的距離H2，以利于大尺寸石料的排出。
Improved nesting structure, increasing the discharge opening from the board of H1 and tilt angle α, reducing the backlog blanking, blanking conducive to the smooth natural discharge; increasing the lower end of the boom cylinder connection with the host nesting distance H2, in order to facilitate discharge large stone.
4、使用說明書規(guī)定對(duì)積存料定期清除的要求。改進(jìn)后，活塞桿未再發(fā)生彎曲。
Use the instructions provided on the accumulation of material removed regularly request. After the improvements, the rod bent not happen again.
