主轴

The invention belongs to the field of mechanical manufacture equipment, in particular to a serial A/B shaft mainshaft head structure which is driven by a telescopic branched chain and can be matched with other devices so as to carry out the composite processing.

本发明属于机械制造设备领域，特别涉及一种能配合其它装置进行复合加工的用伸缩支链驱动的串联式A/B轴主轴头结构。

Machine drive principle: No matter it is mono-block type or detached type, we take electromotor as original motor to convey the power to retarder input shaft (high-speed rotation axle) through direct connection or triangular belt and retarder output shaft (low-speed rotation shaft) connects directly with the joint screw or low-speed rotation shaft connects with the main shaft joint screw through coupling thrust bearing socket.

机械传动原理：本司产品无论是整体式的还是分体塑料再生机，均以电动机为原动机，通过直连式或三角带将电动的力传递给减速器轮入轴由减速器输出直通联接螺杆或经低速轴通过联轴器止推轴承座主轴联接螺杆，使螺杆按设计要求及生产工艺要求的扭矩和转速匀速地旋转，以达到塑料塑化后定压、定量、均匀地连续挤出的目的。

The linear velocity of the press roller is about 2.5m/s, which can exhaust the gas out of materials effectively and heighten the compact degree of the pellet product.

主轴的转速约为60rpm。■压辊的线速度约为2.5m/s，可有效去除物料中的气体，增加了产品的紧密程度。

Ring gauge and part of the cap enters that gauge, at least 5 mm of the length of the cap

采用的笔帽其垂直主轴环直径规格为16 (+0.05，-0) mm ，且笔帽插入部分至少5 mm 长

Mm diameter ring gauge of 19 mm

采用的笔帽其垂直主轴环直径规格为16 (+0.05，-0) mm

There are bearing pedestal and blowing case on the main machine base. There is grinding case on the blowing case, whose middle part has multilayer dial equipping on the main bearing. On each dial, there are numbers of roller, and there are corresponding ring for each dial.

主机机座上装有轴承座及进风壳体，进风壳体上装有磨腔壳体，套装在主轴上的多层转盘位于磨腔壳体中部，在每层转盘圆周上均布有数个环辊，磨腔壳体内圆周有滚道的磨环。

In order to adjust the request, the major problem is that, the dynamic balancing of the Rice mill shaft is not resolved.

要达到以上要求，对于国产碾米机最主要的问题之一就是碾米机主轴的动平衡问题。

In this paper, the principle of dynamic balancing for rice mill shafts is studied.

研究了碾米机主轴部件的去重动平衡原理，详细讨论了动平衡解耦原理、重径积计算中去重质量质心位置的轴向变动等问

So based on the kinetic analysis of the Rice mill shaft, to resolve the dynamic balancing problem, it has very important theory and practicality signification for the rice mill manufacturing.

因此，对碾米机主轴部件进行动力学分析，解决碾米机的动平衡问题，对我国的碾米机制造业有着重要的理论意义和实用价值。

Rice mill shaft as the important component of the machine, have some original not dynamic balancing on its complicated structure. It leads to the machine become more vibration、yawp、abrasion、shortening parts' life and low precision.

碾米机主轴部分是碾米机械的关键部件，其结构形状比较复杂，存在多处原始的动不平衡因素，正是由于这种动不平衡造成了碾米机的振动加剧、噪声增加、成米精度差，而且还加剧了零件的磨损，降低了产品的使用寿命。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
