Structure and Principle

This refiner is made up of main body, coupling and feed gear, etc.

1.Main body

The refiner has 2 CZPT sections. By the inclination angle of abrasion pattern, 4 CZPT plates are fixed, 2 left and 2 right. Two left plates are fixed on inner wall of machine shell and inside of rotating disc and 2 right plates are fixed on outside of rotating disc and moving pedestal, forming 2 CZPT sections (see drawing for installation instruction). Stock is conveyed to CZPT section through inlet pipe. After beating and refining, pumped out from the CZPT section and flows into shell, at last discharged from outlet pipe.

There are 2 bearings on the main shaft and fixed by bearing pedestal and connected to motor via coupling by Nylon column pins. The turntable is on the other side of the main shaft. And there are CZPT discs on each end of the turntable, and the turntable rotates between 2 CZPT discs and axially moves under pressure.

Movable pedestal is adjusted by feed gear with axial movement to adjust the space between 2 CZPT sections. A feather key is set between movable pedestal and machine case and pushed by trapezoidal screw.

The cover is a welded structure which is connected with the case by pin roll. Withdraw the whole movable pedestal into the cover and loosen the locking bolts before opening the cover. Keep the surface clean and withdraw the movable pedestal into the cover before closing the cover. Then fix uniformly fasten bolts.

2.Coupling

Coupling is connected by Nylon column pin with the character of easy dismounting and maintenance. It meets the requirement of displacement of feeding and relieving and transmit torque

3.Feed gear

Feed gear covers worm gear reduction system. Under force of worm gear, trapezoidal thread screw rotates and drive the movable pedestal forward or backward. The movable pedestal moves 0.23mm for each circle of motor. When rotating clockwise, it moves forward while anticlockwise backward.

公司简介

标准长度花键轴

标准长度花键轴采用低碳钢制造，适用于大多数维修工作、定制机械制造以及其他众多应用。所有标准长度花键轴的长度均为 2-3/4 英寸，全花键轴可提供任意长度，其他材质和工作长度可根据要求提供报价。CZPT 制造公司荣幸地提供这些标准长度花键轴。

碟式制动器安装接口为花键式

碟刹安装接口有两种常见类型：花键式和中锁式。花键式碟刹更为常见，通常也更容易安装。中锁式碟刹则需要使用工具拆卸碟轮毂上的锁紧环。六孔碟片安装更简便，仅需六颗螺栓。中锁式碟刹常用于高性能公路自行车。
柱式碟刹需要柱式转接器，而平装式碟刹则不需要。柱式转接器更为常见，常用于碳纤维山地车，而平装式接口正逐渐成为公路车和砾石公路车的标准配置。不过，所有碟刹转接器都可调节以适应不同的碟片尺寸。公路车通常使用 160 毫米碟片，而山地车则使用 180 毫米或 200 毫米碟片。

螺旋花键式碟刹安装接口

螺旋花键式盘式制动器安装接口采用花键连接轮毂和制动盘。这种花键连接允许制动盘和轮毂之间有较大的径向和旋转位移。如果花键连接松动，制动盘相对于轮毂的移动会导致异响。
刹车盘和轮毂上的花键通过气隙连接。该气隙有助于减少刹车盘向轮毂的热量传导。本发明解决了刹车松开时刹车盘的噪音、发热和回缩问题，同时也解决了刹车盘的倾斜和拖拽问题。如果您不确定这种安装方式是否适合您，请咨询您的技师。
采用螺旋花键的盘式制动器安装接口可与其他车轮部件配合使用。它们尤其适用于轮毂对轮毂组件的盘式制动器安装接口。间隔元件（优选沿圆周方向布置）无论制动盘如何旋转，都能提供基本相同的功能。优选地，制动盘周围布置3个间隔元件。每个间隔元件与制动盘花键和轮毂之间的间隙均相等。
间隔元件 6 包括螺旋弹簧部分 6.1 和沿切向延伸的钩状结构 6.4。这些钩状结构在两个方向上均与制动盘 1 抵靠。螺旋弹簧部分 5.1 和 6.1 具有足够的刚度以吸收径向冲击。间隔元件沿啮合区域的圆周布置。
一种螺旋花键盘式安装座包括一个由螺旋弹簧构成的稳定元件。该螺旋弹簧延伸至盘片的花键和齿上。延伸段的两端向相反方向延伸，两端的支架分别与盘片的花键和齿啮合。该稳定元件沿盘片宽度轴向布置。
螺旋花键式碟刹安装接口在自行车和公路自行车中应用广泛。这种接口可靠耐用，是安装刹车的理想选择。花键广泛应用于航空航天领域，具有更高的疲劳寿命和可靠性。花键式碟刹与五通轴之间的接口由铝和醋酸纤维制成。
由于花键轮毂以螺旋方式安装碟片，弹簧钢丝与碟片 2 将紧密接触。弹簧钢丝与碟片接触时，会产生均匀分布在整个碟片上的摩擦力。这使得碟片能够进行大范围的轴向运动。与同类产品相比，采用螺旋花键的碟式制动器安装接口具有更高的强度和刚度。
螺旋花键式碟刹安装接口可以有多种花键表面。花键表面是碟刹安装接口中最常见的类型。它们通常由不锈钢或铝制成，可用于各种应用。但是，花键式碟刹安装座无法支撑带有超大尺寸刹车卡钳的碟刹盘。
