UGEARS - Differential (educational ) - 3-D Wooden Puzzle - Mechanical Model Kit

The UGears STEM LAB Differential Wooden 3D Model is a stylised educational model, an interactive study guide to the mechanism, for learning its essentials and principles of working. The Differential was designed to ensure that the drive wheels sitting on the same axle rotate with a different rate and cover different distances at the same time. This mechanism allows the car to make turns without the wheels skidding, prevents wheel-slip, reduces tyre wear, and makes entering and going out of turns easier for the driver. Having assembled the Differential, you can unblock it pushing the lever in position 1 (Up) and set both wheels in motion by rotation of the drive gear or the wheel. The Control lever regulates the smooth locking of the left and right wheels independently by turning left or right respectively. In the down position of the lever, both wheels are linked in a rigid coupling and can either rotate together (propelled by the drive gear or a wheel) or lock simultaneously (by the lever of the wheel).

When and who invented it
The car differential was invented by French engineer Onesiphore Pecqueur in 1825. In the 1930s of the 20th century, German automotive engineer Ferdinand Porsche made significant improvements to the device.

Usage
Differentials are used mainly in cars as a part of the transmission mechanism. They improve maneuvrability and performance of a car.

Assemble it and discover the principle of working of the Car Differential.

  • Experiment: the model comes with a Pocket Model s Study Guide with a creation story and mechanism design as well as engaging and interesting tasks.
  • Immerse yourself in Augmented Reality (AR), find out how the Counter is used in a production line, and interact with it via the dedicated Ugears application.

The mechanism of the Differential is composed of:

  • The drive gear
  • The locking lever
  • The side gear
  • The locking clutch
  • The wheel

The Differential is developed to serve as a learning tool rather than a puzzle.
Just like the rest of Ugear s collections, putting STEM-lab models together is fun and comprehensive: everything you need to build, learn, and discover comes in a box. There you will find:

  • High-quality wooden boards with pre-cut details and other standard supplies. Assembly requires no glue or additional tools. The details come out of the boards with a slight push.
  • Detailed step-by-step color instruction manual. Easy to follow easy to learn.
  • Examples and suggestions for your fun hands-on projects.
  • QR-code to Pocket Model s Study Guide (the Differential Essentials with a description of the mechanism, principle of working, main characteristics, definitions, and formulas).
  • QR-code to Ugears AR Application. New exciting features from Ugears to make your learning experience even more fascinating!

When such rare cases arise, you will be contacted via email with shipping options and/or an Oakridge team member will try to reach out to you via your telephone contact information, to inform you and offer some shipping options and estimates.

RETURNS & REPLACEMENTS:


DEFECTIVE RETURNS:

All packaging of products are inspected prior to shipment. If the item is inoperable, and has no apparent damage, it may be considered defective. However, with many hobby-grade hobby and toy items, remote control items, race sets, items (hobby, toy & gifts) that require assembly, and electronic and battery operated items, its often just a better understanding or some guidance that is required. This is why, if you are experiencing a problem, we suggest that you contact our Customer Service Department about the item you purchased, before taking any action. Many times, its a simple adjustment or a missed/incorrect assembly step.

• Used, defective merchandise should be returned directly to the manufacturer for warranty repair or replacement. Manufacturer defects found after the product has been used revert to the manufacturer's warranty and usually require proof of purchase (a copy of which can be obtained upon customer request), and they will handle any problems for you directly. Be sure that you have already sent your warranty card in for the item. Any and all Defects/Returns are returned at the customer's expense as we do not reimburse or pay for shipping.
• Since many manufacturers insist on handling defects directly, assistance with missing puzzle pieces, paint-by-number paints, model parts, slot car parts, remote control parts, doll house parts, toy parts, or missing instructions must be handled directly with the manufacturer for warranty repair or replacement. Any and all Defects/Returns are returned at the customer's expense as we do not reimburse or pay for shipping.
• If you have not used the product, and you feel it is defective, we suggest that you contact our Customer Service Department immediately for our help, before taking any further action. If it is determined that an item is defective, the instructions on how to handle defective product situations will vary, since many manufacturers insist on handling defects directly.
• Items that are 
in new and unused condition, and determined by our Customer Service Department to be Defective merchandise, and are approved for return directly to us by the manufacturer, must have a Return Authorization Number. Without a Return Authorization, your return will not be accepted, authorized or recognized, regardless of any proof of mailing. The Return Authorization Number must be clearly marked on the outside of the package in large bold print and adjacent to the address label. 
• Any and all Defects/Returns are returned at the customer's expense as we do not reimburse or pay for shipping. We also will not pay for any postage due on any Returns.
• Upon return and inspection, if there are no used or abused issues, we will send you a replacement at no extra charge.
• All authorized defective product returns are handled as an exchange only.

In almost every case, these issues always work out to our customers' 100% satisfaction.



DAMAGED RETURNS:

All packaging of products are inspected prior to shipment. Damaged merchandise includes items that have been damaged in shipping.
• If a shipment arrives at your door, in hand by our carrier, with apparent shipping damage, please refuse the delivery and make sure that the driver marks "Damaged" on the box and makes note of it in his/her system/hand pad.
• If you find the delivery left at your door and it is damaged, take pictures of the damages and provide these to our customer service department, so that we can forward your claim to our carriers.
• If you have already accepted delivery and then find shipping damage, please call our Customer Service Department immediately. Save all packaging material and paperwork; do not throw anything away! If you attempt to return the merchandise yourself, you will jeopardize our chances of making a claim, and you may not receive credit for the return. In many cases you will be required to take pictures of the damages and to provide these to our customer service department, so that we can forward your claim to our carriers.

Once we get acknowledgement and a approval disposition from our carriers, we will send you a replacement at no extra charge. In every case, these issues always work out to our customers' 100% satisfaction.

 

RETURNING RESELLABLE MERCHANDISE:

We will accept merchandise for return that was purchased from Oakridge Hobbies, within 30 days of receipt.

All authorized returns are subject to a 15% Restocking Fee. Shipping Fees are not refundable.

Opened packaging, broken seals, items removed from packaging, used, tested, abused, crashed items, running fuel through a model engine, installing radio parts in a model, cutting up or opening parts in kits, running out of materials provided in a kit, discarding the packing material are some examples of what constitutes used and unreturnable merchandise.
• We do not accept returns via COD or billed to Oakridge Hobbies, or its affiliated websites, in any way. No refund will be credited for any shipping costs. No returned merchandise will be accepted without an authorization number.
• Any and all Returns are returned at the customer's expense as we do not reimburse or pay for shipping. We also will not pay for any postage due on any Returns. (Also see our Special Promotions Section regarding orders received via a "FREE SHIPPING" offer/promo.)
