Description
Technical field
The utility model relates to a kind of reductor, particularly relates to a kind of rail mounted Special speed reducer for construction hoist.
Background technology
At present, rail mounted elevator is the general vertical transportation machinery of elevator machinery industry in the world, and be well known that three transmissions of no band counterweight and two transmission devices of band counterweight, output gear is three and two.Do not have the installation of counterweight, run safer, but the wearing and tearing of gear, tooth bar are very fast, and during operation, gear pressure is comparatively large, and vibration is comparatively large, and service life is short; Have the accident often having a variety of causes to cause counterweight to drop from eminence when the installation of counterweight, operation to issue, safety is poor.Impulsive force to rack-and-gear for this reason when manufacturer can only use frequency conversion or soft-sphere model instead to reduce start and stop, in the hope of improving the operational safety performance of product, but the service life of gear, tooth bar is still shorter.
It is lower to there is operating characteristic in its product, there is certain potential safety hazard.
Summary of the invention
The utility model mainly solves the deficiencies in the prior art, there is provided a kind of structure simple, operationally power is passed on tooth bar, to reduce the operating pressure to tooth bar unit area, thus the impact shock reduced when running, mechanism is operated steadily, reduces the rate of wear, drastically increase the safety performance of product, thus reach the rail mounted Special speed reducer for construction hoist improving product object in service life technically.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of rail mounted Special speed reducer for construction hoist, comprise casing, input module and output precision is provided with in described casing, described input module comprises transmission shaft and input shaft, described transmission shaft overcoat has crowngear, the head of described input shaft is provided with the input crowngear be meshed with crowngear, on described transmission shaft, cover has the bridge shaft clamping plate rotated with input shaft for a pair, bridge shaft is provided with in described bridge shaft clamping plate, on described bridge shaft, cover has carrier gear, and on described transmission shaft, cover has the transmission gear be meshed with carrier gear;
Described output precision comprises output shaft, and on described output shaft, cover has the output drive gear be meshed with carrier gear, and the external part cover of described output shaft has output pinion;
Described input shaft is driven by motor, and described output precision is provided with two, and the output drive gear in two output precisions and the carrier gear of an input module form isosceles triangle shape and distribute.
As preferably, the bottom of described casing is provided with drain oil, and the bottom of described casing is provided with filler port.
As preferably, described casing is provided with roller.
Principle of work:
Input shaft there is input crowngear, primary transmission gear is formed with the crowngear that transmission shaft is installed, transmission shaft also has miniature gears, with the carrier gear be contained on bridge shaft, is contained in the compound planet gear of output drive gear composition centered by carrier gear on output shaft; Bridge shaft and transmission shaft have bridge shaft clamping plate to be connected, and bridge shaft clamping plate can rotate with two axles; Output pinion, outside casing, can be installed in output shaft one end.
Output shaft and output gear have two covers, and its axle core line is vertical with input shaft axis.
Transmission gear on transmission shaft becomes equicrural triangle to distribute with the output drive gear on two output shafts centered by carrier gear, bridge shaft can with bridge shaft clamping plate around drive axis, to ensure two output drive gears, load is even all the time, and safe in operation is steady.
Secondary gear reduction gear ratio comes suitably to adjust by the number of teeth of secondary gear; The horsepower output of reductor can change corresponding mechanical dimension and realize.
Therefore, rail mounted Special speed reducer for construction hoist of the present utility model, compact conformation degree is high, long service life, can reduce building hoist complete machine cost, operate steadily, and safety performance improves.
