YK2560A数控锥齿轮研齿机

YK2560A数控锥齿轮研齿机

一、 机床结构

采用大、小轮主轴水平放置的卧式布局,小轮主轴为主动轴做H(X)运动,并沿立柱做V(Y)运动。大轮主轴为从动轴做G(Z)运动;V、H、G运动分别由伺服电机驱动精密滚珠丝杠沿直线导轨实现。大、小轮主轴均采用电主轴,转速分别为2400转/分和3000转/分,传动平稳,精度高,噪音小,提高机床使用寿命。机床整体结构紧凑新颖,刚性好,占地面积小,操作者容易接近工件。

二、 机床性能及适用范围

本机床用于高速、精确地研磨最大工件直径达600毫米的弧齿及准双曲面锥齿轮副,适当修正热处理后的变形,研齿后齿面光洁度可达0.8以上,改善接触区位置和大小,传动平稳,降低噪音,提高承载力。适用于修正大、中、小型汽车后桥齿轮热处理后的变形。

三、 机床的主要特点

采用840Dsl数控系统,实现五轴三联动,

安装距可自动调整,

自动认齿并补偿侧隙,识别毛刺和磕碰。通过电主轴施加2~50Nm的扭矩载荷,水平布局直接驱动主轴设计,保持在高速的动力稳定性。在高速情况下,采用双研磨泵将研磨液喷到啮合点上,明显缩短研齿时间,提高生产率,超高速甩净,接触区移动可控,各点速度可控。可回转的操纵箱,更加人性化的人机界面,操作更加方便。防护罩美观安全,自动伸缩的防护门,便于操作者装卸工件。

YK2560A CNC Bevel Gear Lapper

 

. Machine Structure

This is a horizontally displayed machine. The pinion spindle is the driving spindle, which makes the H(X) movements and the V (Y) movements along the column. The gear spindle is the driven spindle and makes the G (Z) movements. All the V, H and G movements are performed through the precision ball screws driven by means of servo motors along the linear guideways. Motor spindles are adopted for both the pinion and gear. The speeds of such spindles are up to 2400rpm and 3000rpm with smooth transmission, high precision and low noise level, thus prolonging the service life of the machine. The new-type machine structure is compact, with fine rigidity and less floor space. The machine operator is easy to access the workpieces.

 

. Machine Performance and Applications

This machine is designed to lap at high speed and precisely the spiral bevel and hypoid gear pairs of diameters up to 600mm, and modify properly the distortions of the gears after the heat treatment. The surface texture after lapping is up to 0.8 and higher, and the positions and sizes of the tooth contact patterns are improved. The gear pairs drive smoothly with low noise, and their load capacity is increased. This machine is suitable for the modifications of gears used on the rear axles after heat treatment for the heavy-duty, medium-sized and light-duty trucks.

 

. Machine Features

A SIEMENS 840Dsl CNC control system is equipped on the machine to perform the simultaneous 3-axis movements, automatic adjustments of the mounting distance, automatic tooth setting and backlash compensation, and the recognitions of burs and collisions. 250Nm toque load can be applied through the high-speed and great torque spindle. Thanks to the direct-driving spindle design of the horizontal arrangement, the machine can sustain the dynamic stability at high speed. Two lapping pumps are used to spray the lapping compound on the meshing point at a high speed. The machine is characterized by the shorter lapping time, increased productivity, ultra-high controllable speed at different points. The machine operation is more convenient because of swiveling control panel and the more humane man-machine interface. The machine enclosure is nice and safe, and the automatic telescopic safeguard door facilitates the loading and unloading of the workpieces.
