主要规格见表1。
表1轴承号9111418轴径D(mm)8090100100110125125140160160180200轴承号222835轴径D(mm)200225250250280300300315335轴承的轴瓦与轴承座采用球面配合，具有自动调心性。
轴瓦的内径尺寸公差由精加工保证，首次使用不须刮研，结构紧凑，安装维修十分方便。
2 产品结构说明2.1 座式滑动轴承结构见附图2.2 轴承结构整体从水平位置分开，关键部件有轴承座、轴瓦、甩油环、浮动密封圈、测温元件等。
2.3 座式球面轴承的两侧密封结构均采用浮动密封。
轴承外盖座内装有浮动密封圈，浮动密封圈由两半组成，通过弹簧固定在轴上，运行时随着轴的位置的变化而自由浮动，材料为可熔性聚酰亚胺,模塑成形。
2.4 油环由冷拉黄铜制成。
在轴瓦内部开有油环槽，油环挂在轴上，下部浸入油中通过轴带动油环旋转，油环将油带到轴上，经导油槽将油较均匀地分配至整个轴瓦承载面。
2.5 为了防止轴电流对轴瓦巴氏合金产生电腐蚀，在滑动轴承与底座之间加有2层绝缘垫板，联接滑动轴承和底座的螺栓采取了可靠的绝缘措施。
电机出厂时，两端轴承与底座之间均带有钢制锥销，电机与整个机组安装调度完毕后，将一端轴承的两钢制锥销取出，换上尼龙锥销，以防止灰尘进入销孔。

4．调心式径向滑动轴承（自位轴承）
特点：轴瓦能自动调整位置，以适应轴的偏斜。
注：调心式轴承必须成对使用。
当轴倾斜时，可保证轴颈与轴承配合表面接触良好，从而避免产生偏载。
主要用于轴的刚度较小，轴承宽度较大的场合。

The standard rated voltage of this series motors are 220V , 380Vt 440Vt 550V and 660V .The voltage beyond above scope can be negotiated when placing ordears.3. Separate excitation is the basic excitation type of this series motors. Four terminals of the excitation winding are divided into two groups. In case the two groups are in series or parallel connection. the excitation voltage is 220V or 100V respectively. Excitation voltage beyond the scope can be negotiated.Forced excitation is allowed with the voltage of less than 500V . During forced excitation I the transient excitation current can exceed the rated excitation current slightly until the excitation current gets stablilized.4. Short time overload capability:The DC motors (class A) can sustain the short time (1 min) overload specified in the following list:Percent of the rated currentPercent of the basic speedoccasionallyoften used 100200300 and above 200180*160140175160*150125The DC motors (class B) can sustain the short time (1 min) overload specified in the following list:Percent of the rated currentPercent of the basic speedoccasionallyoften used 100200300 and above 200180*200180*175160*175160*160140*The data in brackets are applied in case the basic speed of the motors is equal to or greater than the speed specified in the following list:shaft height(mm)315355400450500560 basic speed(r/min)10001000900800710630The occasionally used short time overload capability refers to the motors' capability of sustaining continuous overload within 1 minute in emergent or unusual cases The transient switching device of breaker is suggested to be rectified according to such capability.The often used short time overload capability. as a part of normal operating period refers to the motors' capability of sustaining overload repetatly.After short time overload operation. light load operation is necessary to restrict the load root-mean-square of the whole load period within its continuous rating.The DC motors (Class B) can sustain following contiunous load:(1)Under the rated armature voltage and rated speed the motor can be continuously operated with 115 overload. In this case, temperature rise will be relatively higher, and the otherperformance may be different from those under specified ratings.(2)Soon after continuous operation under rated armature voltage and rated speed. the motor can be operated with 125overload for two hours. In this case. temperature rise will not exceed thespecified value, while the other performance may be different from those under specified raings.Under lower overload, longer time overload is allowed. For the motors (class B). the occasionally used overload times is 2.5 times (under the rated speed) within 15 sec. (please consult with the manufacturer in detail)5. Speed adjustment.No speed adjustment is specified for this series motors. Any special requirements in this field by customers can be discussed.6. Current variation:The allowable current variation( di/dt )of this series motors under all speeds and loads is 200 times of the rated current per second.7.Noise and vibration:The noise level of this series motors conform to the specifications stipulated in ‘Noise measuring Method for Electric Machines of GB2806 and Standard of Noise Level for Electric Machines' of IEC34-9.Vibration of this series motors conform to the specifications stipulated in vibration Measuring Method for Electric.

Shou!d the specification of class B motor be given, one can use the specification list for class A motors to choose the preliminary type of class B. First of all, the rated power of class B motor shall be enlarged by 25%, according to which a corresponding type and specification can be selected out from the specification list for class A. The "A"in the symbol of the selected type,however, shall be replaced with "B" and the capacity shall be replaced with the non-enlarged power(that means with the original capacity of the class B). Final specifications and data can be discussed between customers and manufacturer.For example:Motor required by customer:class B motor of 96kW 220V 185r/minPower enlarged by 25%:120kW 220V 185r/minCorresponding type in the specification list for class A:Z450-2A(118kW 220V 179r/min)Type transformed from class A to class B:Z450-2B(approximate 96kW 220V 185r/min)The motor of this type can basically meet the customer’s requirements.Output-speed conversion (for motors of class A):Besides the five voltages and corresponding outputs and speeds specified in the technical data list, other voltage grades and their corresponding outputs and speeds can be derived from motors of any specifications.

滑动轴承z09
工润滑只能间歇定时供给（油、脂），适用于低速、轻载和不重要场
所。

14.1 滑动轴承
14.1.5 非液体润滑轴承的计算
不能保证液体润滑状态的轴承，统称为非液体润滑轴承。
这种轴承主要的失效形式是磨损，因此，其计算准则主要也是防止 轴承材料的磨损及维持轴颈与轴瓦表面之间的边界膜的存在。
（1）轴承合金 轴承合金又称巴氏合金，分为锡基轴承合金和铅基轴承合金两大类。它 们具有较好的顺应性、嵌藏性、跑合性、耐磨性、浇注性，锡基轴承合金还
有很好的抗胶合性能。但它们的强度、硬度和熔点低，且价格昂贵，因此，
通常将其浇注在软钢、铸铁或青铜的轴瓦基体上作轴承衬来使用。 （2）青铜 青铜是常用的轴瓦材料，它的跑合性能不如轴承合金，但强度高，价格 较便宜。

（2）立式轴环推力滑动轴承
图示为轴环推力滑动轴承，由带有轴环的轴和轴瓦组成。这种轴
承一般用于低速轻载场合。其中左图为单环结构，右图为多环结构， 能承受较大的双向轴向载荷。
14.1 滑动轴承
14.1 滑动轴承
14.1.3 轴瓦的结构和材料
不承受载荷。在上轴
瓦上开有油孔和油沟， 润滑油由油孔输入后，
经油沟分布到整个轴
瓦表面上。
14.1 滑动轴承
油沟和油孔只能开在不承受载荷的区域，以免降低油膜的承载能 力。油沟和油室的轴向长度应比轴瓦宽度短，以免油从两端大量流失。 轴瓦两端凸肩可以防止轴瓦的轴向窜动并承受一定的轴向力。

Z系列座式滑动轴承-
一、产品概述
电机用Z系列座式滑动轴承一般适用于卧式电机或其他卧式旋转机械。
该系列轴承具有结构简单、运行可靠、使用维护方便等特点。
其技术要求、结构与尺寸均符合GB755《旋转电机基本技术要求》及JB/T743《电机用Z 系列座式滑动轴承》。
二、型号说明
M表示轴承座一端带闷盖,不带闷盖时省略
J表示轴承绝缘，不绝缘时省略
轴承标称直径（mm）
轴承系列号
标注范例：Z14-140MJ表示座式滑动轴承系列号14，轴承标称直径￠140mm，一端闷盖式结构，轴承绝缘。
三、技术特征：
Z系列轴承为卧式安装圆柱瓦滑动轴承，它直接安装在主机底座上，一般成对使用，需要防止轴电流时，非主负载端（非轴伸端）选用绝缘轴承。
轴承的润滑一般为油环自润滑方式。
轴承座上附有油标、油环视察窗、进油孔、排油孔等。
主要运行条件如下：
1.适用于转速范围：190～3000 r/min
2.振动值: ≤2.8 mm/s
3.轴承允许的最高温度: ≤80°C
4.最高环境温度: ≤40°C
