Traverse Assembly

Our traverse assemblies are meticulously designed to meet the specific needs of our customers.

Customization of Traverse Assemblies

Our traverse assemblies are expertly tailored to meet the unique needs of our customers, with several essential factors considered during customization :

1. Maximum Traverse Stroke Length

Our traverse assemblies are expertly tailored to meet the unique needs of our customers, with several essential factors considered during customization:

2. Guide Assembly Requirements

We can incorporate appropriate guide assemblies to match your application.

3. Load Carrier

We offer the option to attach a load carrier equipped with linear bearings to the Rollring assembly. This feature effectively reduces the direct load on the traverse unit, enabling it to handle substantial loads with ease.

Our commitment to customization ensures that you receive a traverse assembly perfectly tailored to your needs, whether you require extended stroke lengths, guide assemblies, or the ability to handle heavy loads.

Traverse Assembly Components

A traverse assembly typically includes the following key components:

  • 1. Traverse Unit
  • 2. Shaft
  • 3. Mounting Brackets
  • 4. Steady Rail
  • 5. Guide Assemblies
  • 6. Reversal End Limits

refer figure 16/17

When dealing with heavy loads, excessive winding tension, or guide overhang, it's advisable to incorporate a load carrier with linear bearings supported on guide shafts/rails for enhanced performance.

Shaft Specifications

The shaft is critical for optimal performance and should possess the following attributes:

  • Material: C45
  • Shaft Straightness: Within 50μ per 300 mm
  • Surface Hardness: 58 to 60 HRC
  • Surface Finish and Straightness
  • Tolerance on Diameter: g6
  • Heat Treatment: High-frequency induction hardening
  • Depth of Effective Hardness: 1 to 2.8 mm
  • Corrosion Protection: Hard chrome plating

Shaft Length:

The minimum length between support brackets should equal the maximum stroke length plus L1 (where L1 relates to the length of the traverse unit).

(Refer to Figure 23)

Key Components

1. Guide Rail
Prevents the traverse unit from rotating on the shaft. Ensure that the guide bearing moves unhindered along the rail.
2. Mounting Bracket
Supports the shaft on a bearing.
3. Guide Assembly
The traverse unit's top side features four tapped holes for guide assembly mounting. Ensure the bolt length adheres to specifications to prevent damage.
4. Reversal End Limits
Use a threaded shaft with a nut or a plain shaft with an adjustable stopper to alter the stroke length.

Load Carrier

Reduces the load applied to the traverse unit, enabling it to handle heavy loads. This is particularly useful for applications with heavy guide assemblies, high tension, or twisting forces.

Types of Load Carriers

1. Bearing-Mounted Load Carrier:

A plate with four number radial roller bearings mounted on the traverse unit and supported by a rail. Suitable for normal applications.

2. Load Carrier with Linear Bearing and Guide Shaft:

Features four linear bearings on a load carrier coupled to the traverse unit. Guide assemblies are mounted on the load carrier. Ideal for handling heavy loads.

3. Load Carrier with LM Block and Rail:

Includes four LM blocks on two rails mounted on a machined plate. Suitable for very heavy loads.

4. Bellows:

Bellow-type covers are provided on the shaft to prevent dust accumulation, minimizing wear on the rolling rings and shaft. Specifically designed for dusty environments.

Specialised Configurations

Vertical Traverse Assembly
For vertical take-up or winding, traverse units can operate on vertically mounted shafts. A load carrier with linear bearings and guide shafts is recommended for mounting wire guide pulleys. A counterweight equivalent to the traverse unit's weight is suggested to reduce the force required for upward movement.

Traverse Assembly with Motorized End Limit Control
A small motor facilitates remote adjustment of traverse reversal end limit positions.

Bi-conical Bobbin Winding
In bi-conical bobbin winding, end limits shift as needed during winding, with a PLC controlling the number of bobbin rotations. The stroke length increases based on wire diameter and bobbin taper, managed by a small PLC.

Note: Incorporating these components and considerations ensures optimal performance and adaptability of traverse assemblies across a wide range of applications.

Ball Screw Traverse Assembly

Our Ball Screw Traverse Assemblies are designed for both vertical and horizontal applications, accommodating various load types and optimizing traverse stroke and speed. Each assembly features

Precision Rolled Ball Screw

Includes a matching nut.

Load Carrier

Available with linear bearings and shaft or with LM block and rail.

Drive Options

Choose between AC Motor or Servo Motor.

Control Panel (Optional)

Includes a variable frequency drive for AC motor or servomotors, servo drive, PLC, and necessary accessories.

Maintenance

Lubrication

Shaft:
Apply a very thin film of oil. Clean the shaft before application to ensure an even layer. In dusty environments, clean and reapply oil every shift to prevent dust accumulation, which can cause wear on the rolling rings and shaft. For severe conditions such as high dust, corrosive environments, or extreme temperatures, more frequent lubrication is recommended.

Reversal Mechanism:
Lubricate the springs and reversal lever weekly with high-viscosity oil (SAE 90 or equivalent). Increase the frequency of lubrication in dusty environments to prevent spring breakage.

Spring Replacement:
Ensure the longer end of the spring is inserted into the reversal lever.

Side Thrust:
Traverse units are pre-set for side thrust. If wear on the rolling rings or shaft occurs, the unit may slip or fail to reverse at the end limit. A slotted screw is located on the bottom side of the unit (near the reversal mechanism); tighten this slowly with a screwdriver to adjust side thrust. Avoid overtightening. If wear is significant, replace the rolling rings.

Servicing

We offer repair and service for our traverse units. Units can be sent to our factory for servicing. Please contact us for any service requirements or assistance.
