我們聊聊在機(jī)械設(shè)計(jì)中，我們必須掌握的有關(guān)軸轂聯(lián)接的知識(shí)！軸轂聯(lián)接是軸轂與軸相連接的軸上零件，常見(jiàn)齒輪、帶輪等。聯(lián)接使回轉(zhuǎn)零件在軸上定位和固定，以便傳遞運(yùn)動(dòng)和動(dòng)力。

We talk about the mechanical design, we must master the knowledge about the shaft hub connection. Shaft hub connection is the axle hub and shaft connected to the shaft parts, common gear, belt wheel, and so on. The connection enables the rotating parts to be  and fixed on the axis to transmit motion and power.

鍵是一種標(biāo)準(zhǔn)件，通常用于聯(lián)接軸與軸上旋轉(zhuǎn)零件與擺動(dòng)零件，起周向固定零件的作用以傳遞旋轉(zhuǎn)運(yùn)動(dòng)和扭矩，楔鍵還可以起單向軸向固定零件。而導(dǎo)鍵、滑鍵、花鍵還可用作軸上移動(dòng)的導(dǎo)向裝置。 根據(jù)鍵的結(jié)構(gòu)形式，鍵聯(lián)接可分為平鍵聯(lián)接、半圓鍵聯(lián)接、楔鍵聯(lián)接和切向鍵聯(lián)接等幾類。

The key is a standard part, which is usually used to connect the rotating parts and swing parts of the shaft and the axle to move the fixed parts to transmit rotary motion and torque, and the wedge key can also play a one-way axial fixation part. The guide, slippery key and the spline can also be used as a guiding device for moving on the axis. According to the structure of the key, key joins can be divided into a flat bond, a semicircle bond, a wedge bond and a tangent bond.

銷聯(lián)接一般用來(lái)傳遞不大的載荷或作安全裝置；另一作用是起定位作用。常與帶孔螺栓和六角開(kāi)槽螺母配對(duì)使用，把銷插入螺栓的孔與螺母的槽中，以防螺母松脫。銷按形狀分為圓柱銷、圓錐銷和異形銷三類。

Pin connecti are generally used to transfer small loads or safety devices; the other is to play the role of . It is often paired with hole bolts and six angle slotting nuts to insert the pin into the hole of the bolt and the slot in the nut so as to prevent the loosening of the nut. The pin is divided into three types: cylindrical pin, conical pin and special pin.
