圣霖國際聯(lián)接機(jī)生產(chǎn)品牌企業(yè) 圣霖國際精益求精

與平鍵聯(lián)接比較，花鍵聯(lián)接在強(qiáng)度、工藝和使用方面有下列特點(diǎn)：在軸上與轂孔上直接而均勻地制出較多的齒與槽，故聯(lián)接受力較為均勻；因槽較淺，齒根處應(yīng)力集中較小，軸與轂的強(qiáng)度削弱較少。

Compared with the flat bond connection, the spline connection has the following characteristics in strength, process and use.More teeth and grooves are made directly and evenly on the shaft and hub hole, so the joint force is more uniform.

Because of the shallow groove, the stress at the root of the tooth is small, and the strength of the shaft and hub is weakened less.

型面聯(lián)接：是利用非圓剖面的軸與相應(yīng)形狀的零件的轂孔配合而構(gòu)成的聯(lián)接，作為機(jī)械傳動(dòng)中的聯(lián)接方式，型面聯(lián)接相對(duì)于傳統(tǒng)的鍵聯(lián)接相比，具有聯(lián)接強(qiáng)度高，沒有應(yīng)力集中，可以傳遞大扭矩且的同時(shí)也可以承受沖擊載荷，并且對(duì)于一些大型機(jī)械裝備來講其拆裝方便及維修便利。

is the hub hole type surface connection: the non-circular section axis and the corresponding shape parts with a connection, as the connection mode in mechanical transmission, compared with the traditional linkage type surface connection compared with connecting strength, no stress , can  large torque and high efficiency at the same time it can withstand the impact load, and for some large mechanical equipment for its disassembly and convenient maintenance.

機(jī)用虎鉗的結(jié)構(gòu)及原理。機(jī)用虎鉗是機(jī)械加工中常用的裝夾機(jī)構(gòu)，其結(jié)構(gòu)如圖1所示。其主要工作原理：轉(zhuǎn)動(dòng)方頭帶動(dòng)絲杠，在螺母（通過緊固螺釘固定在虎鉗體上）的作用下，做螺旋運(yùn)動(dòng)的絲杠帶動(dòng)與之聯(lián)接的活動(dòng)座沿絲杠軸線方向來回移動(dòng)。

The structure and principle of machine vise. Machine vise is a common clamping mechanism in mechanical processing. Its structure is shown in Figure 1. The main principle: rotation of the lead screw nut in the square, (fixed in the vise body through a fastening screw) under the action of moving spirally driven screw connected with the movable seat to move back and forth along the screw axis.
