Description

Building hoist spiral bevel gear speed reducer
Technical field
The utility model belongs to a kind of gear reducer for lifter, is specifically related to a kind of building hoist spiral bevel gear speed reducer.
Background technique
Speed reducer is the critical piece on building hoist, and speed reducer is the slow-speed of revolution the high rotating speed speed change of motor, increases torque force simultaneously and drives lift to move up and down, and transports workman and structural material in construction.
Building hoist as a vitals on building construction hoist, is especially being brought into play very important effect with spiral bevel gear speed reducer in high-building construction.Therefore, the performance requirement of speed reducer for construction elevator is higher, requires the features such as bearing capacity is large, compact structure, transmission efficiency is high, safety coefficient is high, noise is low, long service life.
The speed reducer overwhelming majority of using on building hoist is at present the speed reducer of the arc cylinder Worm Wheel System mode of Niemann profile of tooth.This speed reducer performance can meet the demands substantially, but its shortcoming is obvious:
(I) transmission efficiency is low, generally 72%-82%.(II) worm and gear is intermeshing, and worm screw material is the steel that hardness is higher, and worm gear material is that the softer copper of hardness becomes, so worm gear wearing and tearing are more serious, the copper scale that wearing and tearing produce further adds again galling, produces vicious circle.(III) transmission efficiency is lower causes the interior temperature rise of casing higher, in temperature rise in summer, can reach 80 ℃ of left and right, and excess Temperature easily makes Sealing generation deformation or rotten, thereby reduces or lose sealing effectiveness, occurs oil leakage phenomenon.(IV), because efficiency is lower, power consumption is larger, and unit in charge of construction's cost is higher.The critical piece worm gear part material of (V) speed reducer itself is non-ferrous metal copper, more valuable, makes manufacturing enterprise's cost high.
Summary of the invention
The utility model is to overcome the technical problem existing in prior art to propose, and its objective is a kind of building hoist spiral bevel gear speed reducer is provided.
The technical solution of the utility model is:
A kind of building hoist spiral bevel gear speed reducer, comprise casing, lower end at casing is connected with case lid, on case lid, be separately installed with from left to right stifle and gear shaft lower end cap, upper end at casing is connected with respectively transparent cover and gear shaft upper end cap from left to right, right side at casing is connected with motor cabinet, inside, right side at casing is provided with curved-tooth bevel gear wheel shaft by bearing, one end of curved-tooth bevel gear wheel shaft is connected with motor shaft, the other end is processed with bevel gear pinion, inside middle at casing is provided with gear shaft by bearing, in the upper end of gear shaft, curved-tooth bevel gear gearwheel is installed, in its lower end, be processed with small gear, in the inside, left side of casing, by bearing, output shaft is installed, in output shaft lower end, gearwheel is installed.
Described bevel gear pinion and the engagement of curved-tooth bevel gear gearwheel, small gear and gearwheel engagement.
The beneficial effects of the utility model are:
The utility model provides a kind of building hoist spiral bevel gear speed reducer, overcome the shortcoming that existing worm type of reduction gearing exists, the utility model is to take the gear reduction unit that quadrature circular arc cone gear is main parts size, its transmission efficiency is higher, transmission efficiency reaches 92%-95%, reduce energy consumption, reduce costs, meet the requirement of national environmental protection energy-saving and emission-reduction; Frictional loss is little, and temperature rise is lower, extends the working life of the Sealings such as oil sealing, greatly reduces the probability of leakage of oil; The high speed input end of speed reducer provided by the utility model below, make a pair of circular arc cone gear flank of tooth complete wetting of speed end in lubricant oil, lubrication effect is better, and frictional loss is less, further reduce the heat producing owing to running up, make energy be converted into efficiently useful work.
