Product Description

the company has ISO9001, ISO14001, ISO45001 and other system certifications, with the concept of "sincerity, safety, seriousness, service". Based on our resources, professional technical background and company philosophy, we are confident to make and realize our commitment to providing customers with products and services that exceed expectations.The travelling wheel block is a type of travelling wheel installed inside the box, which

can be used for universal applications in all industries. Due to the modular design principle,

the workload control of project engineering, the design and manufacturing costs of

travelling units are minimized. The excellent form and positional tolerance of the travelling

wheel and housing facilitate assembly, reducing installation and alignment work.

1,Small wheel diameter, large load-bearing capacity, perfectly matched with offset

gearbox motors or angular geared motors;

2,DRS112~DRS200 is die cast aluminum material box body, DRS250~DRS500 is

ductile iron material.Integrated processing. Beautiful appearance with excellent positional

tolerance, making installation more convenient and accurate;

3,The surface of the box is coated with corrosion-resistant paint(RAL7001), the wheel

block work better 24/7;

4,Compensation for track center distance offset up to 8mm;

5,Adopting a built-in bearing design for better bearing protection;

6,Lifetime maintenance free design, DRS112~DRS200 bearings maintain lubrication

for life, DRS250~DRS500 has oil replenishment holes, making refueling quick and

convenient;

7,Easily replace the walking wheels and maintain the initial installation state of the

wheel box, without the need to recalibrate the wheel block;

8,Provide a variety of materials and designs for walking wheels to meet various

application needs.

You only need to provide us with the load, travelling speed, and working conditions,

and we can tailor the most suitable plan for you! We will provide you with 2D or 3D

drawings.

1.2 Travel wheel materials

40Cr

DRS112~DRS200 using 40Cr hot-rolled round steel for quenching

and tempering treatment.

DRS250~DRS500 using 40Cr forgings and tempering treatment.

The material has high tensile strength, with overall quenching and

surface quenching treatment HB300-380. The walking wheel has a

guiding function. If wheel flange guidance is used, the minimum

gap between the inner surface of the wheel flange and the edge of

the track can be as small as 1mm. The same gap can also be

obtained by arranging guide wheels. If there is an expected

increase in wear, the walking wheel tread or guide wheel rim can be

hardened to HRC56 ± 2 (HB530) without slipping. The hardening of

the walking wheel is only to reduce wear.

polyurethane

Polyurethane is a synthetic rubber material that has better

resistance characteristics compared to other synthetic rubbers.

Compared with metal materials, polyurethane walking wheels have

a significantly high coefficient of friction, making them suitable for

applications with high dynamic response. It has excellent shock

absorption characteristics, so the walking noise can be minimized.

Please note that compared to metal walking wheels, the

load-bearing capacity of polyurethane walking wheels will be

greatly weakened. Due to the low ground contact pressure, walking

wheels made of polyurethane material are particularly suitable for

walking on concrete surfaces; Due to the high coefficient of friction

between the tread of the walking wheel and the contact material,

polyurethane walking wheels are also suitable for friction driven

applications with acceleration up to 1.5m/s2. In addition,

polyurethane materials are suitable for use at temperatures up to

100 degrees Celsius.

Hardening of wheels

When the running wheels are severely worn during operation (such

as when a large amount of iron filings are found on the track edge),

the tread and rim of the metal running wheels can be hardened (to

a depth of 2-3mm), and the running wheels of DRS112~DRS200

will not have rim damage markings. The hardness value reaches

HRC56 ± 2 (HB530).4

Overview

1.3 Box materials

Materials

DRS112~DRS200

Use high-strength aluminum alloy casting

DRS250~DRS500

Use nodular cast iron QT500.

Paint

DRS112~DRS200

The aluminium wheel block housings are provided with a

weather-resistant powder coating in RAL7001 (silver grey) with a

minimum thickness of 90μm before leaving the factory.

DRS250~DRS500

Primer coat: Single coat of silver grey paint, coat thickness approx.

40μm Finish coat: Silver grey RAL7001, 50% shine, approx. 50μm.

Special paint

DRS112~DRS200

If a non-standard colour is requested (standard RAL7001, silver

grey), the pow-der-coated wheel block is painted over.

DRS250~DRS500

The wheel block housing can be painted in a non-standard colour

(standard RAL7001, silver grey).

Acid-resistant paint

finish, outer surfaces

DRS112~DRS200

The surfaces of wheel blocks with a powder-coated finish may be

used in environ-ments with acid vapours without any treatment.

The gap between the two housing parts and the cover is sealed

with an acid-proof varnish. Wheel blocks must also be fitted with

ball bearings featuring double lip seals.

DRS250~DRS500

Wheel blocks can be supplied with an acid protection paint finish for

applications in environments with acid vapours.5

Overview

 

·Flange guide arrangement

The permissible horizontal force on flange-guided wheel blocks must not exceed 20% of

the actual wheel load.

·Wheel blocks with roller guide arrangement

The permissible horizontal force on wheel blocks fitted with a roller guide arrangement

must not exceed 15 % of the actual wheel load. For DRS112~DRS200 with travel wheel

variant E, the value must be limited to 12%.

Exception: DRS200 with top connection, the permissible horizontal force must be limited

to 10% of the actual wheel load. If higher horizontal loads are to be expected, the roller

guide arrangement can be fitted to the steel superstructure, however, not to the wheel

block.

·Flange guide arrangement Wheel blocks with roller guide arrangement, fitted to

the customer's superstructure

The guide roller arrangement as a solo part may transmit 20 % of the permissible wheel

load when fitted to the customer's superstructure.
