Abstract
The utility model discloses a fourteen-machine-frame heavy load speed reducer which comprises a machine body and fourteen sets of speed reducing devices arranged in the machine body. The fourteen sets of speed reducing devices are divided into an upper layer and a lower layer and are arranged in a staggering mode. Each set of speed reducing device comprises an input shaft and an output shaft which penetrate through the machine body, a first-level gear pair, a first-level transmission shaft, a second-level gear pair, a second-level transmission shaft and a third-level gear pair, wherein the first-level gear pair, the first-level transmission shaft, the second-level gear pair, the second-level transmission shaft and the third-level gear pair are arranged in the machine body. The input shaft is in transmission connection with the first-level transmission shaft through the first-level gear pair, the first-level transmission shaft is in transmission connection with the second-level transmission shaft through the second-level gear pair. The second-level transmission shaft is in transmission connection with the output shaft through the third-level gear pair.
Description
Technical field
The utility model belongs to the speed reducer field, relates to a kind of heavily loaded speed reducer.
Background technique
Existing heavily loaded speed reducer is that 14 three grades of independent transmission soft tooth flank gear speed reducers are combined, because gear pair is the soft flank of tooth, gear material adopts middle-carbon steel, quenching and tempering hardness, and gear hobbing is shaped, not grinding of the flank of tooth; The manufacturer's standard precision is not high, and gear tooth intensity is little, and output power is lower; Make that speed reducer transmission accuracy and transmission efficiency are low, output torque is little, and impact resistance is poor, and tooth surface abrasion is fast, and volume increases, Heavy Weight; Speed reducer is short working life, and operational safety and safety coefficient are less, and many speed reducers are installed inconvenience, the increasing of installation precision error; Noise is big, temperature rise.Compare with the hardened face gear speed reducer, under the identical situation of bearing capacity, volume increases 2/3, and efficient reduces 10%, and bearing capacity only is 1/5, and noise increases 5 decibels.
The model utility content
Technical problem:The utility model provides the 14 frames heavy duty speed reducer of a kind of compact structure, easy for installation, pipe production line that installation precision is high.
Technological scheme:14 frames heavy duty speed reducer of the present utility model, comprise body and 14 groups of speed reducer that are arranged in the body, 14 groups of speed reducer are divided into two-layer being crisscross arranged up and down, every group of speed reducer comprises input shaft and the output shaft that passes body, be arranged on the one-level gear pair in the body, the one-level transmission shaft, the secondary gear pair, secondary drive shaft and tertiary gear pair, input shaft is in transmission connection by one-level gear pair and one-level transmission shaft, the one-level transmission shaft is in transmission connection with secondary drive shaft by secondary gear is secondary, and secondary drive shaft is in transmission connection with output shaft by tertiary gear is secondary.
In the utility model, one-level gear pair, secondary gear pair and tertiary gear pair all adopt hard flank of tooth cylindrical gears.
Beneficial effect:The utility model compared with prior art has the following advantages:
Collecting many independent speed reducers is one, reduces volume, compact structure, easy for installation, has improved installation precision; The reducer gear pair all changes the hard flank of tooth into, and flank of tooth carburizing and quenching, roll flute have improved transmission accuracy, output torque and transmission efficiency greatly; Gear tooth intensity strengthens, and impact resistance is good, has strengthened the safety reliability of speed reducer transmission; Stable drive, noise is little, long service life.
Description of drawings
Fig. 1 is the utility model speed reducer left view, and Fig. 2 is for overlooking section mechanism view.
Have among the figure: body 1, input shaft 2, output shaft 3, one-level gear pair 4, one-level transmission shaft 5, secondary gear pair 6, secondary drive shaft 7, tertiary gear pair 8.
Embodiment
Below in conjunction with Figure of description the utility model is done further and to be specified.
14 frames heavy duty speed reducer of the present utility model comprises body 1 and 14 groups of speed reducer that are arranged in the body 1,14 groups of speed reducer are divided into two rows and are crisscross arranged, the upper strata arranges 7 groups, lower floor arranges 7 groups, and every group of speed reducer comprises input shaft 2, output shaft 3, one-level gear pair 4, one-level transmission shaft 5, secondary gear pair 6, secondary drive shaft 7 and tertiary gear pair 8.Input shaft 2 and output shaft 3 pass body 1, and one-level gear pair 4, one-level transmission shaft 5, secondary gear pair 6, secondary drive shaft 7 and tertiary gear pair 8 are arranged in the body 1.Input shaft 2 is in transmission connection by one-level gear pair 4 and one-level transmission shaft 5, and one-level transmission shaft 5 is in transmission connection by secondary gear secondary 6 and secondary drive shaft 7, and secondary drive shaft 7 is in transmission connection by tertiary gear secondary 8 and output shaft 3.
In the utility model, one-level gear pair 4, secondary gear secondary 6 and tertiary gear pair 8 all adopt hard flank of tooth cylindrical gears.
