Cycloidal Gearbox

The cycloidal pin wheel gear reducer is a kind of planetary transmission principle, which adopts the cycloidal pin gear meshing and planetary transmission principle, so it is usually called the planetary cycloidal reducer. The planetary cycloidal pin gear reducer can be widely used in petroleum, environmental protection, chemical industry, cement, transportation, textile, pharmaceutical, food, printing, lifting, mining, metallurgy, construction, power generation, and other industries as a driving or reducing device. Its unique stable structure can replace ordinary cylindrical gear reducers and worm gear reducers in many cases. Therefore, a planetary cycloidal pin gear reducer is widely used in various industries and fields and is widely welcomed by users.

 Cyclo Gearbox Theory of Operation

Cycloidal gearbox uses the principle of cycloidal gear to provide a high transmission ratio (usually 100:1 or higher), with excellent torsional stiffness, good impact load capacity, stable backlash, and low wear within the service life of the gearbox.

The cycloidal gearbox has many designs, but its basic principle is an input shaft eccentrically mounted on a driving member or , which drives the cycloidal disk with an eccentric motion. When the disc rotates, the convex angle of the cycloidal disc is like a tooth, which meshes with the pin on the fixed gear ring. The cycloidal disc also has roller pins projecting through the disc, which are connected to the output disc, which transmits motion to the output shaft.

The number of convex angles (teeth) on the cycloidal disk is lower than the number of pins (teeth) on the to achieve deceleration and torque multiplication. To prevent the output shaft from “swinging,” the roller pin connected to the output plate is installed in a hole slightly larger than the pin diameter. A single cycloidal disc bears the unbalanced force, which can be compensated using a second cycloidal disc (offset by 180 degrees from the first cycloidal disc).
Cycloidal gear is more challenging to manufacture than involute gear, which requires highly accurate manufacturing and assembly. But they do provide significant benefits in some applications. First, they can provide transmission ratios up to 300:1 in relatively small packages, especially gearbox length, because they do not need to “stack” gear stages like planetary designs.
Because of its rolling contact and lower Hertz contact stress, the friction and wear of cycloidal on the tooth surface are also lower. Its good torsional stiffness and the ability to withstand impact load make it an ideal choice for heavy industrial applications requiring servo accuracy and stiffness.

 Advantages and disadvantages of planetary gearbox

Cycloidal Gearbox Advantages

Cycloidal drives can begin with zero backlash and large torque capacity even though compact in dimension, unlike Involute gearboxes. These are helpful in scenarios wherever reduced speed with higher torque capacity is needed. Cycloidal drives may be developed with drastically larger make contact with places for his or her dimension than any gear-based transmission for example, epicyclic gears, applying force through many of the ‘teeth' at the moment, enabling pretty high torque output for your size with the drive with the price of utilising sliding make contact with.

Cycloidal Gearbox Disadvantages

Due to the eccentric nature of the drive, should the cycloidal disk is not balanced by a 2nd disk or a counterweight, it can generate vibration, which can propagate by way of the driven shafts and physique. This can also cause improved dress over the exterior teeth of the cycloidal disk as component bearings. With two discs, the static imbalance is corrected, but a little dynamic inequality remains; this is frequently viewed as acceptable for most applications, but to cut back vibration higher pace drives use three (or much more) discs to permit the imbalance to be corrected, the outer discs move in unison and in opposition to the middle one particular that's twice as massive.

 Maintenance (Disassembly and Assembly)

Our company manufactures all kinds of cycloidal reducers with the same internal structure, whose disassembly
and assembly has the same order. Lubrication oil should first be run out before disassembly, and the oil
pump of the vertical reducer should be first disassembled.

  1. Disassembly: First, loosen the attachment bolt, disassemble 4 and 10, and then successively disassemble
    parts 6, 7, and 8. Assembly adopts the opposite order.
  2. Assembly
    Following attentions should be paid to assembly:
  • Clean all parts before assembly.
  • Lubricate rolling and sliding surfaces to form the condition of insufficient lubrication.
  • Tags of two cycloidal wheels must be kept 180°.
  • Carefully adjust the spring's elasticity the in the rubber oil seal and lubricate the grease.
  • Inject lubricating oil or lubricating grease after assembly with horizontal oil level up to the red line of oil
    pointer and vertical oil level up to the middle line of the oil pointer.
  • Manually turn high-speed shaft, and make an open drive if the check is OK. Check the working condition of the oil pump of the vertical reducer, and put it into use if the review is OK.
  • Strictly conform to requirements to disassemble the direct-coupled motor, and it is forbidden to start
    disassembly from the motor flange.
