副轴

Its main components comprise the transmission case, input shaft, output shaft, countershaft, driving gear, transmission fork, etc.

它的主要组成部分包括变速器、输入轴、输出轴、副传动轴、驱动装置、变速叉，等等。

Mechanical seal supplied with high pressure sealing water is recommended when the slurry pump is installed in series (two stages and above tow stages).and the expeller seal combined with packing seal is used when the pum is installed in single-stage.

对于多级串联采用填料加副叶轮组合式密封，二级和二级以上轴封水最低压力一般为：Pn=其中n≥2；Hi为等i级泵扬程；Hn为第n级泵扬程。对采用机械密封，各级泵的轴封水压力一般要求比泵出水口压力大0.1MPa。

5S-111GPA has 9 forward speeds, 4 forward speeds of main case shift by ZF-BK short travel synchronizer, auxiliary case shift by lock ring synchronizer, the reverse and crawler shift by joint sleeve. The differential drives front axle and rear axle simultaneously. The output shaft and input shaft swivel in the same direction.

变速器具有九前一倒档，主变速器4个前进档采用ZF-BK型短行程同步器换档，副变速器采用锁环式同步器换档，爬档和倒档采用接合套换档，差速器同时驱动前后桥，其输出轴与输入轴旋向相同。

Therefore, in the present study, a retrograde and anterograde experiments were made in the rat to address this issue. After injection of cholera toxin B subunit, a retrograde tracer, into Barrington's nucleus or D-region, some retrogradely labeled neurons were found in lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus of the lumbosacral spinal cord segments. Injection of biotinylated dextran amine into lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus, respectively, a large number of BDA-labeled axon terminals were seen in Barrington's nucleus and D-region.

发现，将逆行示踪剂霍乱毒素 B 亚单位（ Cholera toxin B subunit； CTb ）注射到 Barrington's 核或 D 区后，在大鼠腰骶髓 I 层、骶髓副交感核和后连合核内分布有一定数量的 CTb 逆标神经元；将顺行示踪剂结合生物素的葡聚糖胺(Biotinylated dextran amine； BDA)分别注射到腰骶髓 I 层、骶髓副交感核和后连合核内后， Barrington's 核和 D 区内出现大量顺行标记的轴突终末。

By chosing the material of axle sleeve with high strength and decreasing the length of contact face for axle sleeve and axle neck, the lubrication condition of frictional pairs was improved, and the wear was decreased.

结果表明，通过选用强度优异的轴套作为摩擦副，缩减沟槽尺寸以增加轴套与轴颈的接触面长度，改善了摩擦副的润滑状况，减少了磨损，满足了生产需要。

The re- quired property of sealing material used in mechanical seals is discussed in this paper.

机械密封是一种依靠弹性元件对密封副预紧，在介质与弹性元件压力共同作用下使密封副压紧而达到密封的轴向端面密封装置，其结构见图1。

Installation of two outer openings each staggered 180b, the inner and outer openings staggered opening 90b, and pin the three rings with a fixed, outer and inner expansion force in self-expansion force of working together, close to the surface of the pump cylinder run, inflation is not only the axial ring sealed, and the radial seal Ye Hao, it prevents micro-fine sand and into the axial friction pair, can also prevent the micro-fine sand and into the internal voids in the inner ring 3, the operation will not impede expansion ring breathing.

安装时2个外环开口互错开180b，内环开口与外环开口错开90b，并用销钉将3个环固定，外环在自身胀力和内环胀力共同作用下，紧贴泵筒内表面运行，胀圈不但轴向密封好，而且径向密封也好，故阻止微细砂进入轴向摩擦副，也可阻止微细砂进入内环3的内部空隙中，不会阻碍胀圈运行中呼吸。

This paper presents the Machining Tool geometry of the former flank, the main flank, flank, the main cutting edge, Under the cutting edge tip cutting plane, the main section, the former Kok, horn, wedge angle edge angle, pointed knife, the blade angle, vice horn, Under the Frontier concept, the concept of cutting consumption, and the general circumstances of their choice method for processing slender shaft. cast iron materials, aluminum, stainless steel, rubber materials, plexiglass material, cloth bakelite materials, high temperature alloys, aluminum-magnesium alloy, hardened steel, the typical trapezoidal thread, the thread Triangle, Speaking at the trapezoidal screw thread pitch of the Tool geometry of the selection methods and cutting the amount of cutting fluids reasonable choice.
