Basic structure of the planetary decelerator
The planetary decelerators consist mainly of the following core components:
1. Core moving parts
• solar wheels: active wheels at the centre, connected to electric axes
• planetary wheel: 3-6 gears rotated around the solar wheel, evenly distributed
• inner cortex: fixed cortex, bound to planetary wheels
• planetary racks: parts that support planetary wheels and transmit twists
The design team of zhejiang senard has optimized the distribution of the components through the three-dimensional modelling of solidworks and has improved the transmission efficiency。
2. Auxiliary support components
• input/output axis: connect to electric power and loads, transfer power
• axis: support the rotational parts and reduce friction
• boxes: accommodate and protect internal components
• seal: prevention of leakage of lubricants and impurities
Ii. Activation principles for planetary decelerators 1. Basic transmission mode
The standard motion pattern for planetary speed-reducing machines is solar wheels active, inner larvae fixed and planetary shelf output. The reduction ratio formula is:
I = 1 + \\frac{z{ring}
Of which:
\ (z ring}: number of inner dentures
\ (z sun}): sun gears
2. Multi-level transmission principles
For the need for a large slowdown ratio, multi-stage cascades are used:
• two-stage transmissions: two single-stage planetary wheel chains
• three-tier transmissions: three single-stage planetary wheel chains
By optimizing the inter-level connectivity structure, senad reduced the additional loss of multi-level movement and improved overall efficiency。
Senna's structural design innovation 1. High-intensity gear design
• material selection: use of scm440h high-strength alloy steel
• thermal process: vacuum seepage carbon fire, tooth hardening hrc60 ±2
• optimization of the carving: rectification, reduction of rodent impact and friction
2. High precision bearing configuration
• axle bearing type: high-precision bearings at the level of nsk or fag p4
• pre-heavy control: appropriate pre-heavy for bearings to reduce gaps and vibrations
• seal upgrades: improved seal reliability through the introduction of german cfw lips seals
3. Rigid box design
• material selection: high-strength cast iron or aluminium alloy to enhance box rigidity
• structural optimization: additional reinforcements and wall thickness to reduce box deformation
• connectivity: high-strength bolts and positioning sales to ensure rigid connectivity

V. Maintenance and maintenance of planetary decelerators 1. Periodic inspection project
• lubricant status: colour, viscosity and impurities
• vibration and noise: abnormal levels
• temperature: whether the temperature of the boxes and bearings is within normal range internal
• sealed state: leaks
2. Lubricant replacement cycle
Senard suggested the first oil exchange after 500 hours of initial operation。
Vi. Selard's composition structure service 1. Special structure
• reload customization: enhanced gear and bearing configuration
• high-temperature/low-temperature custom: introduction of high-temperature/low-temperature materials and lubricants
• clean customization: full-seal structure, no lubricant leak
