What’s in a Constromech Assembly?

Sprocket Rim (drive / idler)

Standard Scope: One-piece or 3-/6-piece segmented rim in quenched-and-tempered alloy steel; precise Pitch Circle Diameter (PCD) matched to chain size

Optional / Spare Items: Spare rim segments; full replacement rims

Replaceable Teeth (DDA / ASP profiles)

Standard Scope: Bolt-on or weld-on teeth, case-hardened to 50–55 HRC for extreme wear life

Optional / Spare Items: Extra tooth sets, shim plates, mounting hardware

Hub

Standard Scope: CNC-bored, key-seated, and stress-relieved steel hub; concentricity ≤ 0.03 mm

Optional / Spare Items: Split hubs for confined installs; taper-lock bushings

Shaft

Standard Scope: Solid or hollow alloy-steel shaft, optional induction-hardened journal zones; supplied with keyways and endcaps

Optional / Spare Items: Spare shafts, woodruff keys, locking assemblies

Bearing Blocks

Standard Scope: Plummer blocks with double-row spherical-roller bearings; factory-packed with high-temp grease

Optional / Spare Items: Labyrinth seals, felt rings, bearing spacers

Sealing System

Standard Scope: Dual labyrinth or contact seals + flinger discs to keep dust and clinker fines out of bearings

Optional / Spare Items: Spare seal kits, grease nipples

Torque Limiter / Backstop (drive end)

Standard Scope: Optional overrunning clutch or hydraulic torque arm for anti-rollback protection

Optional / Spare Items: Replacement backstop elements

Fasteners & Shims

Standard Scope: 8.8 or 10.9 grade bolts, nuts, and spring washers to DIN standards

Optional / Spare Items: Full bolt packs, spacer kits

All components arrive match-marked and serialized for traceability and ease of re-ordering.

Technical Design Highlights

Finite-Element-verified tooth geometry ensures uniform stress distribution and maximizes chain and tooth life.
Pitch accuracy: PCD tolerance ±0.25 mm; axial run-out ≤ 0.05 mm—guarantees smooth chain engagement and reduced vibration.
Induction-hardened tooth flanks (4–6 mm case depth) resist abrasive wear from clinker, slag, and limestone.
Dynamic balancing to G 6.3 (ISO 1940-1) at operating speed prevents premature bearing failure on high-RPM return stations.
Surface shot-peening of rims and teeth improves fatigue strength by up to 30 %.
Pre-greased & plug-sealed bearings mean no field lubrication before start-up.

Operational Advantages

Plug-and-Play Installation
- Pre-assembled shaft–hub–bearing package drops straight into existing pillow-block pedestals or flange interfaces.
Reduced Downtime
- Segmented rims and replaceable teeth allow one-man replacement without pulling the shaft.
Extended Service Life
- Superior metallurgy, deeper case depth, and precision machining cut wear rates, slippage, and chain whip.
Energy Efficiency
- Perfect tooth–chain meshing reduces friction losses and motor load.
Predictive-Maintenance Friendly
- All wear parts (teeth, seals, bearings) are stocked as spares with identical serial references; vibration and temperature points clearly indicated on the hub for sensor mounting.
