SPJ-246-C (0370SH7800) and ASPJ-247-C (0370SH7900) are matched spiral bevel gears made of 20CrMo, suitable for reducers. The unified parameters are pressure angle 20° and module 1.5, which are 37° left-hand (28 teeth, gear ratio 1.428) and 37° right-hand (40 teeth) respectively. Manufactured by precision machining, heat treatment and full inspection, they have high precision and good wear resistance, meeting the needs of reducer transmission matching.
Description
This product is a pair of matched spiral bevel gears, with models ASPJ-246-C and ASPJ-247-C, corresponding to part numbers 0370SH7800 and 0370SH7900 respectively. Both are special transmission gears for reducers, made of 20CrMo alloy steel, which has good strength, toughness and wear resistance, and can meet the requirements of long-term stable transmission of reducers.

The two gears share the same basic core parameters: pressure angle 20°, module 1.5, and the overall processing technology is consistent. The specific process is: Sawing → Turning → Machining Center Processing → Rough Grinding of Clamping Position → Gear Milling → Heat Treatment → Hanging Shot Blasting → Outer Diameter Grinding + Facing → Facing → Gear Grinding (ASPJ-246-C adds an extra rough grinding of clamping position process) → Marking → Full Visual Inspection. Multiple precision processes ensure that the product’s dimensional accuracy, tooth surface quality and appearance meet the standards.

Specific parameter differences: ASPJ-246-C is a left-hand spiral bevel gear with a spiral angle of 37°/L, 28 teeth, gear ratio 1.428, gear outer diameter 43mm, overall length 31.5mm, and single weight 0.1777kg; ASPJ-247-C is a right-hand spiral bevel gear with a spiral angle of 37°/R, 40 teeth, gear outer diameter 60.5mm, overall length 52.2mm, and single weight 0.4027kg. The two gears are meshed in pairs to adapt to the specific transmission ratio requirements of the reducer.
