Embodiment Construction

[0012] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0013] Such as figure 1 The special reducer for cooling towers and air coolers shown includes connecting plate 1, gear box 2, bearing seat 6, driving gear 3, driven gear 4 and main shaft 5, and connecting plate 1, gear box 2 and bearing seat 6 pass through The bolts are connected as a whole, which is very convenient for assembly, disassembly and maintenance. Based on this split structure, the driving gear of the general reducer is easily damaged and needs to be repaired or replaced. Therefore, when it is necessary to repair or replace the driving gear, it is not necessary to replace the entire When the reducer is removed from the equipment, it is only necessary to remove the connecting plate and the driving gear as a whole, which greatly facilitates the maintenance of the reducer.

[0014] The upper bearing of the main shaft 5 is installed...

Abstract

The invention discloses a speed reducer special for a cooling tower and an air cooler. The problems that noise pollution of a planet-gear speed reducer which is matched with an existing cooling tower and an air cooler is serious, 'slipping' happens to a belt speed reducer, and the rotating speed of a fan is made to be unstable are solved. The speed reducer achieves deceleration by the way that a pair of spiral gears is meshed with each other. The speed reducer is structurally composed of a connecting disc, a gear case and a bearing pedestal. Through bolt connection, assembling, disassembling and maintaining of the speed reducer are all very convenient. A driving gear is assembled in the connecting disc through a combined type structure and stretches into the gear case in a cantilever mode to be meshed with a driven gear. The driven gear is arranged on a spindle, an upper bearing of the spindle is mounted on the gear case, and a lower bearing of the spindle is mounted in the bearing pedestal. A single direction thrust ball bearing is used for bearing axial force.

Description

technical field [0001] The invention relates to cooling tower and air cooler technology, in particular to a speed reducer applied to cooling tower and air cooler fans. Background technique [0002] Cooling towers and air coolers are devices that use a reducer to drive a fan to increase the flow of air to take away the heat of cooling water from industrial equipment or refrigerators, and reduce the temperature of the cooling water to achieve circulating water cooling. [0003] Cooling towers or air coolers installed close to residential areas have particularly strict noise requirements and require a high speed fan. For this type of cooling tower, belt reducers are widely used as the transmission device for fans. The transmission principle of the belt reducer belongs to friction transmission, relying on friction to transmit the power of the motor to the large pulley through the small pulley. Although the friction transmission between the V-belt made of rubber and the pulley ...
