Abstract
The utility model relates to an upside-down type low-noise speed reducer of a cooling tower, which is characterized in that a speed reducing mechanism is composed of a hypoid conical driving gear 4 and a hypoid conical driven gear 5 which are in a curve tooth shape, wherein, the axial lines of the driving and the driven gears are arranged in an inclined mode and in a 90 DEG different plane vertical mode; an axis of a motor is connected with the driving gear 4 by a connecting axis sleeve 2 and a flat key arranged in the sleeve to transfer torque to the driven gear 5; the driven gear 5 is linked with an output axis 7 by a bolt to transfer power to the output axis. In the embodiment, the motor 1 is connected with a connecting flange 3 to form an integral body. The utility model has the characteristics of small axial size, compact structure, and lowering noise. The utility model is especially suitable to be arranged in a cooling tower in an upside-down mode, and thereby, the speed reducer which is traditionally matched with the cooling tower and a mounting method are changed. The utility model is good for reducing cost of the cooling tower and enhancing performance.
Description
The utility model relates to speed reducer, particularly a kind of upside-down mounting type low noise speed reducer of cooling tower.
At present, domestic medium-sized glass fibre reinforced plastics cooling tower generally adopts belt speed reducer or planet-gear speed reducer as transmission device, speed reducer is installed in the cooling tower top, the weight and the dynamic load of speed reducer and blower fan are born by tower body, and this is all totally unfavorable to the noise that reduces glass fibre reinforced plastics cooling tower, because of motor and speed reducer on same axis, the oversize existing tower of axial dimension must increase height could be adopted, it is affected in application, and waste material increases cost.
The purpose of this utility model provides a kind of employing Hypoid Gear Drives principle, in conjunction with medium-sized glass fibre reinforced plastics cooling tower structural feature and transmission requirement, can reduce the cost of cooling tower and the upside-down mounting type low noise speed reducer of cooling tower of noise.
Above-mentioned purpose of the present utility model is to realize by such technological scheme, it is a kind of upside-down mounting type low noise speed reducer of cooling tower, comprise motor and reducing gear, it is characterized in that: reducing gear is the driving and driven gear of hypoid circular cone of a pair of employing curve profile of tooth, and it is vertical that wherein driving and driven Gear axis is biased to 90 ° of antarafacials; Motor shaft is connected by the flat key in coupling band and the cover with driving gear, and moment of torsion is passed to driven gear, and driven gear and output shaft are given output shaft with Bolt Connection with transmission of power.
Said structure of the present utility model is further specified by the embodiment that accompanying drawing provides.
Accompanying drawing is a structure sectional view of the present utility model.
Referring to accompanying drawing: the upside-down mounting type low noise speed reducer of cooling tower among the figure, comprise housing 6, motor 1 and reducing gear, it is characterized in that: reducing gear is the driving and driven gear 4,5 of the hypoid circular cone of a pair of employing curve profile of tooth, and it is vertical that wherein driving and driven Gear axis is biased to 90 ° of antarafacials; Motor shaft is connected by the flat key in coupling band 2 and the cover with driving gear 4, and moment of torsion is passed to driven gear 5, and driven gear 5 is given output shaft with output shaft 7 usefulness Bolt Connection with transmission of power.In the present embodiment, motor 1 is connected as a single entity with adpting flange 3.
It is vertical that reducing gear of the present utility model adopts curve profile of tooth, driving and driven Gear axis to be biased to 90 ° of antarafacials, the diameter and the helix angle of driving gear are big, the strength of gear teeth is improved greatly, gear is in transmission process, the load that acts on gear increases gradually from entering engagement, break away from engagement and minimizing gradually, Nie He tooth remains on more than two pairs at least simultaneously.Therefore, it is very steady to turn round, and noise is low, efficient is high, and bearing capacity and velocity ratio are big, reliable performance and compact structure.It with the cylindrical gear of straight tooth velocity ratio of power, noise reduces more than 5 decibels at least.
The utility model is owing to adopt the speed reducer structure of described structure: the retarder axis is become 90 ° of layouts with electrical axis, directly be connected as a single entity, axial dimension shortens greatly, and compact structure is particularly suitable for the mounting type of upside-down.Only need the housing structure frame is changed a little, just can be supporting with the speed reducer of the utility model structure.
Use of the present utility model both can be installed in cooling tower intake pipe top, also can be on steelframe with the structural frame two supports, no longer load-bearing and make tower ancient piece of jade, round, flat and with a hole in its centre attenuate of tower body, cost will be reduced significantly, adopt the utility model deceleration function that the integrated noise of tower body is descended significantly, can be near the effect of belt speed reducer.Reason is: determined its noise low 4-5 decibel than the planet-gear speed reducer of same specification on, transmission principle; Two, because different with existing speed reducer mounting type, structural frame directly is not connected on the tower, has avoided causing because of the vibration of speed reducer the vibration of tower body, and noise is reduced; Three, because the center of gravity that the utility model speed reducer is installed is lower, tower body becomes the natural barrier of speed reducer noise transfer.
In sum: for medium-sized glass fibre reinforced plastics cooling tower, adopt speed reducer described in the utility model supporting,, significantly reduced of the pollution of planet-gear speed reducer noise to environment with the cost of tower is reduced; Saved the tired brain of belt conveyer again, also eliminated the burden that outer transmission speed reducer is installed because of the belt elongation.Axial dimension is short, and compact structure is particularly suitable for upside-down installation in cooling tower, has changed supporting speed reducer and the mounting type of cooling tower tradition, and is very beneficial for reducing the cooling tower cost and improving performance.
