Description
Technical field
The utility model belongs to mechanical manufacturing field, relates in particular to the novel hoisting speed reducer of a kind of car hosit with the self-regulated heart function.
Background technology
Reductor is the mechanical drive of national economy numerous areas, industry related products classification has comprised all kinds of gear reduction units, planet-gear speed reducer and worm decelerating machine, also comprised various dedicated transmission, product support area relates to industries such as metallurgy, coloured, coal, building materials, boats and ships, water conservancy, electric power, construction machinery and equipment and petrochemical industry.Hoisting speed reducer is a kind of reductor, be mainly used on all kinds of elevator machineries, be characterized in utilizing gear, planetary wheel to make the speed conv, the revolution of motor is decelerated to desired revolution, and obtaining the mechanism of torque greatly, the effect of hoisting speed reducer mainly contains: reduction of speed improves output torque simultaneously; Slow down and reduced the inertia of load simultaneously.The car hosit of conventional structure adopts the planetary wheel drive mechanism of inner gear output mostly with hoisting speed reducer, supported as the left side of winch by a pair of tapered roller bearing through pretension, the right right-hand member support of supporting by the band tilting bearing retrains, the advantage of this transmission device is that messenger chain is short, the mechanical efficiency height, it is less to take up room, and is used on the lifting mechanism of car hosit in a large number.Conventional structure is owing to the bearing brackett of reductor is all captiveed joint with reel with inner gear, the bearing brackett of reductor and inner gear and reel connect firmly and are integral, thereby require high to two hole right alignmenies of hoisting speed reducer mounting bracket, because car hosit drop-gear box frame processing at present is because of the technological ability restriction, weld behind many employing fine limit works, be out of shape comparatively seriously, cause elevator cabinet working accuracy to be difficult to improve, become the technical task that current car hosit industry is difficult to break through.If elevator cabinet working accuracy is not high, directly cause the rotation axis of reel to tilt, bearing brackett and inner gear rotation axis that the rotation axis of reel tilts will cause to connect firmly with it also produce simultaneously, cause gear and the local additional harmful stress of bearing in the running to increase, light then cause the bearing localized wear of reductor to increase that efficient reduces, gear teeth face increases because contacting the inhomogeneous abnormal sound that causes, heavy then because of gear and the damage of the local sharply wearing and tearing of bearing et out of order.In order to overcome above-mentioned defective, the utility model provides a kind of car hosit with the self-regulated heart function novel hoisting speed reducer, change the hoisting speed reducer inner gear of conventional structure the connection of into short gear coupler relocation mechanism with being connected by captive joint of reel, when the reel rotation axis produces bigger leaning angle because error appears in support two end supports hole right alignment, the rotation axis of reductor inner gear is not subjected to the restriction of reel rotation axis fully, thereby the gear that guarantees reductor meshes all the time at the correct engagement state; The utility model is selected the spherical outer ring deep groove ball bearing for use simultaneously, makes the reel rotation axis that the adjustment capability of bigger angle displacement be arranged, thereby eliminates the additional harmful stress on the bearing.After using the spherical outer ring deep groove ball bearing following advantage is arranged: 1. the intrinsic gap of fixed end bearing is kept, have the aligning ability, can perfectly remedy the negative effect that elevator cabinet working accuracy deficiency is brought; 2. mechanical model is better, the harmful stress that did not exist the location to cause; 3. good manufacturability, the deep groove ball bearing structure is easily assembled, is dismantled, and processing technology is simple; 4. spherical outer ring deep groove ball bearing structure friction force is little, the mechanical efficiency height.The spherical outer ring deep groove ball bearing is with after the globe bearing bearing matches, can discharge the degree of freedom of angle displacement, right-hand member support by the band tilting bearing that links retrains, can allow spool axis that the certain angle displacement capacity is arranged, eliminate the harmful stress problem that causes reducer gear and bearing because of reductor support two end supports hole decentraction fully, after above-mentioned technical innovation, the utility model product is compared with the conventional hoisting speed reducer of same specification, and it is simple to have production technology, dependable performance, productive costs is low, can improve 2 times of hoisting speed reducer life-spans with first-class series of advantages.
Summary of the invention:
The problem that the utility model mainly solves provides the novel hoisting speed reducer of a kind of car hosit with the self-regulated heart function, this hoisting speed reducer improves the structure of conventional hoisting speed reducer, change the hoisting speed reducer inner gear of conventional structure into short gear coupler relocation mechanism with the captive joint of reel and be connected, can guarantee that the gear engagement of reductor is all the time at the correct engagement state; Select the spherical outer ring deep groove ball bearing simultaneously for use, make the reel rotation axis that the adjustment capability of bigger angle displacement be arranged, can eliminate the additional harmful stress on the bearing, have that vibrations are little, noise is little, the advantage of long service life.
The technical solution adopted in the utility model is:
The novel hoisting speed reducer of a kind of car hosit with the self-regulated heart function comprises: the right-hand member of reductor 1, spherical outer ring deep groove ball bearing 2, globe bearing bearing 3, inner gear 4, reel 5, band tilting bearing supports 6; Power is from the left end input of reductor 1, final output inner gear 4 outputs by reductor 1, inner gear 4 is floated by short gear coupler relocation mechanism with reel 5 and is connected, give reel 5 transmission of power, the steel rope of hoisting crane is wrapped on the reel 5, the left end of reel 5 is supported on formation left side support on the reductor body through globe bearing bearing 3 and spherical outer ring deep groove ball bearing 2, and the right-hand member of band tilting bearing supports the right support of 6 formation.
Further technical scheme of the present utility model is:
