YKD2280數控弧齒錐齒輪銑齒機

YKD2280 CNC SPIRAL BEVEL GEAR GENERATOR

一．機床用途及使用范圍

YKD2280型機床為精密數控弧齒錐齒輪銑齒機，可用于加工直徑800毫米，模數15毫米范圍內的各種格里森齒制的弧齒錐齒輪、準雙曲面齒輪和等高齒齒輪。

本機床刀具裝在搖臺上（圓導軌），該結構整體剛性強，工作平穩，精度高。亦可用于硬齒面刮削，該搖臺結構式齒輪機床經久耐用，正常使用壽命可達數十年。

本機床的性好，適合大批量生產粗、精加工中、重型卡車、礦山機械、工程機械、船舶齒輪。

本機床采用西門子828D數控系統和交流數字伺服系統，具有三個數控軸：工件（Y軸）、搖臺（X）軸、床鞍（Z軸），可實現三軸聯動，刀具主軸（S軸）采用交流變頻調速，使機床無需改變任何掛輪可實現切削運動，操作更方便，柔性強，使只具有機械銑齒機操作調整經驗的人員能將常用的YT2250（或Y225）、Y2280等機床調整卡的有關參數轉換為本機床的相應參數使用。

二．機床主要特點：

采用交流變頻電機作主驅動動力源，而搖臺和工件主軸都由伺服電機驅動，床鞍進給由伺服電機通過滾珠絲杠驅動，簡化了傳統的機械結構，無需更換掛輪減少了機床調整時間，縮短了傳動鏈，不但提高了機床精度，而且使操作更為準確、方便。本機床可配置安全防護罩和自動排屑器。機床的密封電氣控制柜可配置空調。

Ⅰ. Applications of Machine

  Model YKD2280 machine is a precision CNC Spiral Bevel Gear Generator, which is designed for roughing and finishing Spiral Bevel Gears and Hypoid Gears ａnd Equidepth gears of the Gleason system with the diameter up to 800mm and module 15mm.

  On this machine, the cutter is mounted on the cradle (circular guideway). The integral structure is rigid, highly accurate ａnd working stably. The cradle-type gear cutting machine, which is also possible for hard surfacing, is durable and the service life will be several dozens of years under normal operating conditions.

  The machine is with universal features and it is suitable for roughing and finishing, in mass production, gears used for medium & heavy load trucks, mining machineries, construction machineries and shipbuilding industry.

  The machine is equipped with a CNC control system 828D (SIEMENS) and designed to operate as a three-axis machine, i.e. cradle rotation (X axis), work spindle rotation (Y axis) and sliding base movement (Z axis) being simultaneously controlled by the CNC control system to cut gears. The rotation of cutter spindle (S axis) is controlled by an A.C. frequency-variable motor for its stepless control. Therefore, no change gears will be used on the machine for cutting gears. The machine operation is easy and flexible.  The clients who have the conventional machines can convert the machine settings used for YT2250 (or Y225) and Y2280 machines into the machine settings for the YKD2280 machine.

Ⅱ. Main Features of Machine        

  An A.C. frequency-variable motor is used as a main driving power source while the cradle rotation ａnd work spindle rotation are driven by the servo motors. The sliding base movement is driven by a servo motor through a ball screw.  All of these features of the machine are for the purpose of simplifying the conventional mechanical structure, reducing the machine setup time and shortening the transmission train because of the change gears elimination.  In this case, not only the machine accuracy is increased, but also the operation is easy and convenient.  Safety guards and an automatical chip conveyor may be provided on the machine. The machine is equipped with a sealed electrical cabinet which is with an air conditioner.

Ⅲ. Power Supply: 380V, 50 HZ

Ⅳ. Main Electrical Parameters:

   A.C. Frequency-variable Motor (main drive)        15KW, 1500rpm

   Servo Motors (cradle & workhead)                42NM, 1500rpm

   Servo Motor (sliding base movement)             23NM, 2000rpm

   Total Power Capacity                                    35KVA
