A smart lock drive often places a motor, gear train and latch mechanism inside a narrow housing. Laiwei manufactures custom spur gears for suitable electronic lock mechanisms according to customer drawings or samples. The tooth profile, bore and mounting features can be specified to fit the actual assembly.
For a new design or replacement project, the most important information is the mating gear, shaft interface and available clearance. We review the module, tooth count, face width and mounting geometry against those requirements. The lock manufacturer should validate operating cycles, sound and security performance in the complete product.
| Parameter | Specification basis |
|---|---|
| Gear type | External straight-tooth spur gear |
| Module, tooth count and pressure angle | Lock gear train drawing |
| Diameter and face width | Available housing space |
| Bore, hub and retention features | Shaft and assembly design |
| Material and finish | Customer use requirements |
| Inspection | Critical tooth and fit dimensions |
| Order quantity | Confirmed by quotation |
Compact dimensions can be matched to the lock housing.
Mounting features can follow the specified motor or latch drive design.
Drawing-based production supports replacement of gears that standard parts cannot match.
Electronic door locks, cabinet locks, safe-lock drives and other compact lock actuators using suitable spur gear transmissions.
Laiwei supports drawing-based and sample-based custom manufacturing. Its machining and gear inspection capabilities help customers define and check the critical interfaces of a lock drive component.
1. Can you make a gear for an existing lock?
Yes. A drawing or sample, together with mating gear and shaft details, will help us assess it.
2. Do you supply a complete smart lock?
This page covers a gear component. Any assembly requirement needs a separate technical discussion.
3. Can you make a special hub or retention feature?
Yes, subject to drawing review and manufacturing feasibility.
4. Can you guarantee the lock’s cycle life?
The complete lock must be tested against the customer’s defined cycle-life requirement.
5. What information is needed for pricing?
A drawing or sample, quantity, material requirement and critical mating dimensions.
