Core parameters (TJQ9)

Compatible reducer: B7

Output shaft diameter: 110 mm

Input interface: 650 × 590 × 520, bolt 12-M22 (22 × 12)

Output interface: 560 × 650 × 700, bolt 12-M27 (28 × 10)

Installation related: H ≈ 955, H1 ≈ 210, H2 ≈ 420; Keyway 160 × 200, key 12 × 100 (common)

Selection and installation points

Selection principle: Match the output shaft diameter of the reducer with the frame; When the interface size is consistent, the shaft diameter can fluctuate up/down within a certain range, and non-standard connections can be made with flanges.

Installation method:

No pivot point: equipped with JQ/JJQ clamp type coupling, suitable for mixing with light load and low axial force.

Single pivot point: equipped with HL elastic pin coupling, priority is given when there is no bearing pivot point at the shaft seal.

Double pivot: Used in heavy-duty/high-speed/shaft end deflection sensitive situations, the lower pivot is commonly equipped with a self-aligning roller bearing with a tightening sleeve and a column pin coupling.

Material and environment: gray cast iron HT250 or Q235 welded, with reinforcement in key areas; Surface protection or stainless steel can be used in dusty/humid/corrosive environments.
