The gear reducer is an external meshing involute helical cylindrical gear reducer manufactured according to the national professional standard ZBJ. Gear reducers are widely used in East China. They are the rotating mechanism of tatami-type lifting machinery and are widely used in metallurgy, mining, hoisting, transportation, cement, construction, chemical, textile, printing and dyeing, and pharmaceutical industries. What are the model parameters of the gear reducer?
1. R-type coaxial gear reducer series
GR series gearboxes are helical gear reducers. GRX series gearboxes are single-stage helical gear reducers. GRXF series gearboxes are flange-mounted single-stage reducers. GRF series gearboxes are flange-mounted. GR...F series gearboxes are foot-mounted, and GRZ series gearboxes are B14 flange-mounted. The R series gearboxes have six types that can be combined into similar types, such as GR17, GRX27, and GRXF37. It matches the basic model number of the gearbox with the numerical model number, similar to RXF57-42-Y80-4-M1, R57-52-Y804-M1, RX57-62-Y80-4-M1, and RF57-72-Y80-40-M1. They use the basic type + numerical model + reduction ratio + motor model (frame number) + number of motor poles, thus forming many combinations.
2. F-type parallel shaft reducer series
The basic types of parallel shaft reducers are as follows: GF mounting parallel shaft-helical gear reducer; GFA…B mounting foot hollow shaft; GFV…B mounting foot spline hollow shaft; GFA hollow shaft mounting; GFV mounting spline hollow shaft; GFAF is B mounting five-flange hollow shaft; GFVF is B5 flange mounting spline hollow shaft; GFAZ is B14 flange mounting; GFVZ is B14 flange mounting spline hollow shaft; GFF is B5 flange mounting; GFH…B foot hollow shaft locking device; GFH mounting hollow shaft locking device; GFHF is B flange hollow shaft locking device; GF HZ is B type mounting flange hollow shaft locking plate.
3. K-series bevel gear reducers
The GK… base is equipped with a spiral bevel gear reducer; the GKA…B spiral gear reducer is mounted on a hollow shaft in the base; the GKV…B base has a splined hollow shaft; the GKH…B base has a hollow shaft locking plate; the GKF is equipped with a B5 flange; the GKAF is equipped with a B5 flanged hollow shaft; the GKVF is a B5 flanged hollow shaft; the GKHF is a B5 flanged hollow shaft; the GKHF also includes a B5 flanged hollow shaft locking plate, GKA hollow shaft, GKV splined hollow shaft, and GKH hollow shaft locking plate; the GKT is equipped with a hollow shaft torsion arm; the GKAZ is equipped with a B14 flanged hollow shaft; the GKVZ is equipped with a B14 flanged hollow shaft; and the GKHZ is a B14 flanged hollow shaft locking plate. This basic model is more common, with hollow shafts being the most prevalent. This type of reducer also comes in various types.
4. S-shaped helical gear worm gear reducer
This type of worm gear reducer has eight basic models. The GS model has a helical gear worm gear reducer, the GSA model has a helical gear worm gear reducer, the GSAF model is a B5 flange mounting type, the GSAZ model is a B 14 flange hollow shaft mounting type, the GSF model is a B flange mounted helical gear reducer, the GSH model has a hollow shaft locking disc, the GSHF model is a B 5 flange hollow shaft locking disc, and the GSHZ model is a B flange mounted hollow shaft locking disc.
Gear reducers? To adapt to fierce market competition and better serve the domestic metal products industry, the design of wire drawing machine transmission systems is shifting towards hardened gear transmission. Specifically, the combination of high-strength narrow V-belts and dedicated hardened gear reducers for wire drawing machines is now widely used in the market. Standard reducers adapted to the overall structure of the wire drawing machine are used, and these reducers are effectively integrated with the mounting housing, main shaft, drum, etc., to form a wire drawing machine transmission system with hardened gears as the main transmission form.
