Indexing tables rotate a workpiece or assembly through a series of fixed stations, with each indexing move needing to land precisely at the same position cycle after cycle across potentially millions of cycles over the equipment’s service life. Positioning drift that would be tolerable in many applications compounds into real production quality issues on an indexing table, where each station’s tooling and processes assume the workpiece arrives at exactly the same point every time.
Ever-Power’s PC+NMRV helical-worm series is specified into indexing table applications across Australian manufacturing and assembly automation, where the combination of low backlash, self-locking station holding, and compact right-angle output suits this demanding positioning duty. This page covers the technical fit for indexing table drives, three manufacturing facility deployments, and answers to specification questions from equipment designers.
| 인덱싱 테이블 수요 | PC+NMRV 설계 응답 |
|---|---|
| 수백만 주기 동안 일관된 스테이션 위치 유지 | 백래시가 적은 헬리컬 프리 스테이지는 위치 오차 누적을 최소화합니다. |
| 스테이션 프로세스가 진행되는 동안 위치 유지 | 셀프록킹 웜 출력단은 연속적인 서보 토크 없이도 위치를 유지합니다. |
| 역 간 빠른 인덱싱 | Helical stage’s higher input speed compatibility supports fast indexing motion |
| 테이블 아래에 차지하는 공간이 작습니다. | 직각 출력 구성은 일반적인 인덱싱 테이블 장착 공간에 적합합니다. |
문제점: 다중 스테이션 조립 인덱싱 테이블에서 장기간 생산 과정 동안 점진적인 위치 오차가 발생했는데, 이는 원래 구동 메커니즘의 백래시 누적 때문인 것으로 밝혀졌습니다.
해결책: PC071+NMRV050 교체품은 검증된 낮은 백래시 성능을 제공하여 장기간의 생산 캠페인 전반에 걸쳐 일관된 스테이션 위치를 유지했습니다.
결과: 업그레이드 후 진행된 대량 생산 과정에서도 위치 일관성이 유지되었습니다.
문제점: 전자 테스트 인덱싱 테이블은 생산량 증가에 맞춰 스테이션 간 이동 시간을 단축해야 했지만, 테스트 장비에 필요한 위치 정확도는 유지해야 했습니다.
해결책: PC063+NMRV040 specified for servo compatibility supporting the faster cycle rate while maintaining the table’s required positioning tolerance.
결과: Increased production cycle rate achieved while maintaining the testing station’s positioning accuracy requirement.
문제점: A precision machining facility’s rotary workholding indexer needed exceptionally reliable station holding during cutting operations, where any drift would directly affect part accuracy.
해결책: PC080+NMRV075는 가공 주기 동안 낮은 백래시 위치 지정과 확인된 자체 잠금 유지 기능을 결합하도록 지정되었습니다.
결과: Consistent part accuracy maintained across the indexer’s production schedule following installation.

The helical pre-stage’s lower inherent backlash compared to a worm-only input reduces the rate of positioning error accumulation over extended service life. Actual long-term accuracy depends on your specific load, ratio, and duty cycle — we can discuss expected performance characteristics for your application during specification.
The gearbox itself drives the table’s rotational positioning; the number of index stations is determined by your table and tooling design rather than the gearbox. Provide your station count and required index angle per cycle, and we will confirm the appropriate ratio for your specific indexing pattern.
Yes, the NMRV worm output stage’s self-locking behaviour above the standard ratio threshold holds the table in its indexed position without requiring continuous servo holding torque, which is valuable during station operations like machining or precision assembly where positional stability matters.
Achievable cycle rate depends on your specific ratio, servo motor capability, and the table’s mechanical design including inertia and required index angle. Provide your throughput target and table specifications, and we will confirm whether your target cycle rate is achievable with the appropriate gearbox configuration.

PC+NMRV units typically carry a higher unit cost than standard NMRV due to the additional helical stage, reflecting the improved backlash and efficiency performance. Whether this premium is justified depends on your specific positioning tolerance and cycle rate requirements — we can advise on whether your application genuinely needs the helical-worm combination or whether standard NMRV meets your needs at lower cost.
