Custom POM Industrial Gear Pump Timing Gear
Tianjin SWKS Technology & Development Co., Ltd. develops drawing-based POM molded components for industrial metering pumps and fluid-transfer drive assemblies. The gear pump timing gear is configured around the customer's mating hardware, available installation space and operating duty. Product images illustrate a representative finished design; dimensions, material formulation and interfaces are established in the approved project specification.

Timing within the pump drive
This acetal gear is developed for a customer-defined timing or drive position in industrial pumping equipment. Its tooth geometry coordinates rotary movement with the mating gear and shaft arrangement. Clarify whether the part works in an external transmission chamber, a lubricated enclosure or the pumped fluid. A timing gear and a fluid-displacing pumping gear can share a similar appearance while having different clearance, sealing and loading requirements.
Tooth form and mating mesh
The gear drawing should identify tooth count, module or diametral pitch, pressure angle, face width and any specified profile correction. A photograph alone cannot establish the correct mesh. Tooth thickness and center distance determine the intended backlash together with the mating wheel. The customer defines the operating relationship, and SWKS reviews the proposed molded geometry against that specification before a tool is prepared.
Shaft interface and angular reference
The bore can be a plain register, a keyed connection or another approved drive interface. For a keyed design, provide key width, engagement length, shaft tolerance and the angular relationship between the keyway and teeth. A short hub can help locate the gear axially, but its seating face must match the actual shaft stack. Retention by a clip, nut or neighboring shoulder is separately defined in the assembly.
POM formulation and running conditions
Material selection considers rotational speed, transmitted torque, temperature, lubricant and cycle pattern. Start-up, reversal and occasional stall conditions can be different from continuous running. The resin formulation is therefore selected for the real transmission duty, including any fluid contact and additives. A representative molded gear has no universal torque capacity; the approved design and its validation establish the permissible operating envelope.
Hub transitions and molded tooth quality
The hub-to-web transition and tooth-root region should be considered together. Unnecessary mass at the hub can affect molding uniformity, while an undersized web can change how load reaches the tooth face. Gate and ejector locations are planned around the tooth flanks and shaft references. The acceptance criteria should describe flash, gate vestige and surface condition on the working teeth so appearance checks support the actual mesh.
Meshing trials and inspection records
Prototype or first-off gears should be assembled with the intended mating wheel at the specified center distance. Check rotation, backlash and contact through the full turn rather than at one angular position. The equipment team defines load, noise, temperature and endurance trials for the pump drive. Dimensional reports can include bore size, hub position, tooth-related checks and any runout requirement identified on the gear drawing.
Timing marks, lubrication and spare-part identification
A molded timing mark or orientation feature can assist installation when the pump requires an indexed relationship. Its location should be controlled from the keyway or another functional datum, not merely placed on a convenient free surface. Communicate how the drive is lubricated and whether the gear needs an oil route or clearance around a retaining washer. Revision identification can help distinguish gears that look alike but have different pitch, tooth count or shaft interfaces.
Information needed for a timing gear quotation
Send the complete gear definition, mating wheel data and shaft section. Include the normal speed, peak and continuous torque, operating temperature and lubricant identity. State the quantity for sampling and the expected recurring requirement. Where a master gear, inspection fixture or accepted physical sample is available, identify it with the drawing revision. These inputs allow the molding proposal and approval plan to focus on the pump transmission rather than an approximate tooth shape.
