On the described brake casing 1 breather stem vent plug 1-1 is arranged.Reductor can produce a large amount of heats in long-term high-speed operation process; Cause the reductor inner chamber to produce the het expansion phenomenon; For fear of the too high infringement that sealing member is caused of inner chamber air pressure; Increase breather stem vent plug (1-1) device at brake casing 1, in order to keep the balance of reductor inside and ambient pressure.
During use, captive joint with the frame of elevator machinery through the tapped bore of brake casing 1 and fixed bearing 17, the input end of brake axle 29 links to each other with HM Hydraulic Motor 30.The utility model has four kinds of mode of operations, and promptly quiescence, power-lift state, power are transferred state and empty hook is put state soon.The principle of work of existing each state of accompanying drawings the utility model.
1) quiescence
The utility model hoisting speed reducer does not receive the effect of any external force under this state, and promptly HM Hydraulic Motor 30 does not provide input torque, and the oil inlet passage of drg and power-transfer clutch does not have any system oil pressure.At this moment, drg and power-transfer clutch are in normally off.Complete machine remains static under the static friction force effect between the friction lining.
2) power-lift state
When the utility model was in the power-lift state, power-transfer clutch must be in closure state, and is promptly static relatively between friction lining, power take-off shaft 11 and the clutch-bell cover 10.Simultaneously drg is in opening, and the unlatching of drg needs hydraulic efficiency pressure system that enough response pressures are provided, and its piston moves, length of spring compressed, makes between moving plate and the stator of friction lining to throw off.Meanwhile HM Hydraulic Motor 30 drives brake axles 29 and rotates, and the planetary gear train that brake axle 29 drives in the planetary reducers rotates, pass through the double reduction of planetary reducer like this after transmission of power to power take-off shaft 11.Power take-off shaft 11 is through moving plate 22 engagements of male splines and power-transfer clutch; Because of power-transfer clutch is in closure state, like this, moment of torsion is delivered on the clutch-bell cover 10 through friction lining by power take-off shaft 11; Clutch-bell cover 10 is fixed with one with reel 3 again; Moment of torsion is delivered on the reel 3, and power take-off shaft 11 drives reel 3 and rotates, and has realized lift operations.
3) power is transferred state
Power is transferred with the power principle that hoists basic identical, and just reel 3 rotations is in the opposite direction, is become by the flake down state and puts the rope form attitude.By HYDRAULIC CONTROL SYSTEM; Make HM Hydraulic Motor 30 counter-rotatings; The output torque direction of brake axle 29 and planetary reducer is also opposite, and power take-off shaft 11 counter-rotatings are in reel 3 and put the rope form attitude, and the realization weight is transferred; Because of the whole speed transferred in the process transferred fully by the control of HM Hydraulic Motor 30 output speeds, thereby can guarantee that weight steadily transfers.
4) empty hook is put state soon
When starting the fast playing function of empty hook; Power-lift should be stopped and power is transferred operation; Under this state, general HM Hydraulic Motor 30 remains static, and drg should be in closure state at least; Make brake axle 29 and planetary reducer not have takeoff output, open power-transfer clutch simultaneously and just can realize the fast playing function of empty hook.Specific operation process is following: make arrester close, planetary reducer remains static down, with reference to figure 1, Fig. 2; System is through swivel coupling 19, oil inlet passage 11-1 and seal oil chamber 12-1; Give power-transfer clutch certain unlatching oil pressure, piston 12 moves to right under the effect of system oil pressure, and compression cluster spring 14; Make between moving plate 22 and the stator 21 and throw off; No longer include friction force between the friction lining this moment, and clutch-bell cover 10 is thrown off with power take-off shaft 11, make reel 3 fully with power take-off shaft 11 disengagings.And between reel 3 and described planetary reducer and the drg bearing I 4 is arranged; Between reel 3 other ends and the fixed bearing 17 bearing II 18 is arranged, bearing is also all arranged inside and outside the clutch-bell cover 10, so reel 3 has only one degree of freedom at this moment; Under the pulling force of suspension hook deadweight, rotate; Suspension hook is done the movement of falling object of weight, does not need extra power, realizes that empty hook puts soon.Its beneficial effect is, accelerated operating speed, improved work efficiency, simultaneously in the dropping process without any need for power, significantly reduced energy consumption, and safe in utilization, reliable.
