جلبة عمود نقل الحركة
Countershaft Bushing
Identify parts for Metso cone crushers, check models and drawing numbers, confirm materials and processes, and submit an inquiry.
المعدات, Models and Drawing References
Identify the installed machine model and key dimensions, then check the part number, drawing number, drawing revision and physical interfaces.
Models and Key Dimensions
Metso HP Series (HP100-HP800), GP Series (GP100-GP550) and MP Series
Drawing Number / Part Number
See the OEM part number table below
Provide the equipment nameplate, complete model and existing part number so that the installation position and drawings can be checked.
Drawing Revision
Confirm dimensions by measuring the sample or using the customer drawing. Cross-check the drawing revision against the model on the equipment nameplate.
المواد والعمليات
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
C95400 aluminum bronze (ASTM B148)
Aluminum bronze sand casting; verify composition, as-cast or heat-treated condition and mechanical properties against ASTM B148 and the drawing.
C93200 leaded tin bronze (SAE 660)
Leaded tin bronze bearing material; verify composition and properties against the applicable standard and supply condition, and maintain the lubrication specified by the equipment design.
C54400 Phosphor Bronze
Wrought leaded phosphor bronze; verify properties and load requirements against the product form, supply condition and drawing.
Wear and Replacement Criteria
Common wear patterns and maintenance guidance are outlined below. Determine replacement intervals from operating conditions, processed material and equipment performance data.
Common Wear Patterns
- Gear mesh forces cause uneven bushing wear, with one side wearing faster than the other.
- Inadequate lubrication causes direct metal contact between the bushing and journal, producing heat and seizure.
- Extended operation enlarges the bushing bore and gear mesh clearance, increasing noise and vibration.
- Contaminated lubricant causes scoring on the bushing surface.
Replacement Criteria
Check bushing bore wear and clearance against the maintenance limits for the model. Inspect the bushing if abnormal gear noise persists after adjustment, and replace it if seizure marks or extensive scoring are present. Check the gear tooth contact pattern after replacement.
Materials and Process Control
تعتمد متطلبات المواد والمعالجة الحرارية والتركيبات المركبة والفحص على الرسم المحدد وظروف التشغيل والمراجعة الفنية.
Material Grade / Substrate
C95400 aluminum bronze (ASTM B148), C93200 leaded tin bronze (SAE 660), or C54400 phosphor bronze
Heat Treatment Condition
اتبع المعيار المطبق لدرجة المادة؛ وأكِّد متطلبات المعالجة الحرارية والصلادة وفقًا للرسم.
Composite / Hardfacing Requirements
الجلبات البرونزية غير مناسبة للإصلاح باللحام التراكبي. استبدل الجلبة المتآكلة كقطعة كاملة؛ ولا يُنصح بإصلاح السطح.
Dimensions and Inspection
يتم التصنيع وفقًا لرسومات منتجة من قياسات القطعة أو مقدمة من العميل. تتبع تفاوتات أسطح التزاوج الحرجة متطلبات الشركة المصنعة الأصلية. استخدم فحص UT/MT لتقييم المسبوكات من حيث المسامية الانكماشية والشقوق وفقًا لمعايير القبول المتفق عليها.
قد لا تكون الأجزاء التي تحمل الاسم نفسه قابلة للتبادل بسبب اختلاف طراز الماكينة أو مراجعة الرسم أو واجهة التركيب أو مواصفات المادة. يُرجى استخدام الطراز الكامل والرقم التسلسلي ورقم الرسم والرسم قبل التصنيع.
