Abstract
The utility model relates to a right-angle planetary speed reduction device, which comprises a shell, a spiral bevel gear pair, a sun gear and a planetary transmission mechanism, wherein the spiral bevel gear pair and the sun gear are arranged in the shell, and the planetary transmission mechanism consists of an inner ring gear, a planetary gear and a planetary carrier. The right-angle planetary speed reduction device has the main points that the spiral bevel gear pair consists of a spiral bevel driving gear and a spiral bevel driven gear which are equal in depth of tooth; the spiral bevel driving gear is provided with a power input shaft; and the planetary carrier is provided with a power output shaft. The right-angle planetary speed reduction device is simple in structure, easy in manufacturing and low in manufacturing cost. When the spiral bevel driving gear and the spiral bevel driven gear which are equal in depth of tooth are adopted, the noise is small and the bearing strength is high when the gears are meshed, thereby, the durability and the reliability of the speed reduction device are improved, the service life of the speed reduction device is prolonged, and the operation and maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of gear drive, is specifically related to a kind of right angle planetary reduction gear transmission device.
Background technique
The gear reduction transmission device has obtained using widely in engineering machinery; Stir companion's machine like mixed earth and just generally adopt the gear reduction transmission device, its structure of this speed reduction gearing is: convergent tooth (tapered tooth) formula helical bevel gear (umbrella gear) and planetary pinion drive mechanism are formed.Big, the easy heating of the noise that sends during its engagement of this convergent tooth (tapered tooth) formula helical bevel gear, working gear temperature height, working life is short, poor working environment.Install silencer, service intermittent additional or install cooling unit additional, can enhance heat with reduce noise, improve working environment, guarantee the normal operation of equipment.But install the heat radiation that silencer can reduce gear again additional, installing cooling unit additional can increase working service operating cost again, and service intermittent can reduce the equipment rate of attendance again.This just needs, and a kind of noise is little, the gear reduction transmission device of good heat dissipation effect.
Summary of the invention
The purpose of the utility model is the shortcoming that will overcome above-mentioned technology, provides a kind of simple in structure, and the operation noise is little, temperature is low, long service life, the right angle planetary reduction gear transmission device that use and maintenance cost is low.
The right angle planetary reduction gear transmission device of the utility model; The epicyclic transmission mechanism that comprises housing, is arranged on spiral bevel gear pair and the sun gear in the housing and constitutes by ring gear, planet wheel, planet carrier, it is characterized in that: spiral awl driving gear, spiral awl driven gear that described spiral bevel gear pair is equated by tooth depth constitute; Spiral awl driving gear is provided with power input shaft, and planet carrier is provided with pto.
The right angle planetary reduction gear transmission structures of the utility model is simple, easy to manufacture, manufacturing expense is low; The employing Equal-Height Spiral Bevel Gear is secondary; The noise of gear engagement is little, bearing strength is high; Improve serviceability, reliability and the working life of speed reduction gearing, reduced the device use and maintenance cost.

Among the figure: 1, spiral awl driving gear, 2, spiral awl driven gear, 3, ring gear, 4, planet wheel, 5, sun gear, 6, planet carrier, 7, housing, 8, power input shaft, 9, pto.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe:
The right angle planetary reduction gear transmission device of the utility model, the epicyclic transmission mechanism that comprises housing 7, is arranged on spiral bevel gear pair and the sun gear 5 in the housing 7 and constitutes by ring gear 3, planet wheel 4, planet carrier 6.Spiral awl driving gear 1, spiral awl driven gear 2 that spiral bevel gear pair is equated by tooth depth constitute; Spiral awl driving gear 1 is provided with power input shaft 8, and planet carrier 6 is provided with pto 9.
The utility model is work like this:
The power input is by power input shaft 8 inputs on the spiral awl driving gear 1; Through spiral awl driven gear 2; After the epicyclic transmission mechanism that passes to sun gear 5 successively and be made up of ring gear 3, planet wheel 4, planet carrier 6 slows down, by pto 9 outputs that are arranged on the planet carrier 6.
