Description
Technical field
The utility model relates to gumming device manufacturing technology field, is specifically related to a kind of three fast xanthating machine special reduction gears.
Background technique
Xanthating machine belongs to viscose glue and produces key equipment, and pulp, through dipping, squeezing, cooled soda cellulose, complicated physical and chemical changes occurs in xanthating machine reactor.In the different phase of reaction, require that the stirring in the reactor of xanthating machine provides different power and speed, so that whole process can complete smoothly.And the motor reducer of standard generally can only provide a speed, therefore the requirement of production can not be met, transmission of power in whole course of reaction must be completed to sacrifice seed output and quality.
Xanthating machine is in the past mini-plant, and the power that speed reducer needs is less, specifically describes as follows:
Working principle: reference Fig. 1, reductor shaft Z11 are pto＝power take-off, stir be connected with reactor.Axle Z5 is double-speed motor input end, and motor and speed reducer adopt hydraulic couplers to be connected, and double-speed motor power and rotating speed are respectively 90kW, 960r/min and 110kW, 1450r/min.Axle Z1 and motor adopt hydraulic couplers to be connected, and power of motor and rotating speed are 75kW, 1450r/min.
A speed reducer has three rotating speeds to realize in the following way simultaneously:
Speed reducer Z5 axle is equipped with free wheel device C8, the internal surface of C8 coordinates with the optical axis position of Z5, the inner hole of outer surface and gear Z4, at the two ends of C8 by good Z5 and Z4 of bearings, to ensure that Z5 and Z4 is coaxial.When the double-speed motor be connected with Z5 axle drives, Z4 and Z5 throws off by free wheel device C8, thus ensures that Z3 and Z1 is not dragged, and avoids because the running of Z5 axle drives Z3, Z1 High Rotation Speed to cause driving.
When Z1 axle rotates, by gear and gear shaft, transmission is reached Z4, now free wheel device C8 is used by as non-return device, drives Z5 running, thus transmission is reached Z11.By the function of free wheel device C8, achieve whole speed reducer and can export 3 speed.
Said apparatus Shortcomings:
1, speed reducer needs nonstandard manufacture, and interchangeability is poor, and due to domestic manufacturing firm level limited, cause that speed reducer rate of fault is high, spare parts consumption is high.Similar joint famous brand can not according to nonstandard manufacture.
2, free wheel device C8 is easily damaged parts, needs whole speed reducer to disassemble in Renewal process, causes the repair time long, higher to maintainer's level requirement.Need Z5, Z4 to change when changing free wheel device, and Z5, Z4 gear not yet may wear to the degree needing to change, and causes great waste simultaneously simultaneously.
3, this speed reducer moment of torsion is less, can not meet the requirement that main equipment drives, if again developed, the cycle is long costly.
Summary of the invention
The purpose of this utility model is to provide a kind of three fast xanthating machine special reduction gears, and its design science is reasonable, and speed reducer moment of torsion is large, and adopt two standard speed reducer patterns, add the interchangeability of spare part, overhaul more convenient, rate of fault significantly reduces.
In order to solve the problem existing for background technique, the utility model is by the following technical solutions: it comprises main gear reducer, free wheel device, coupling, secondary speed reducer, one end of main gear reducer is coaxially connected with free wheel device, one end of free wheel device is coaxially connected with secondary speed reducer by coupling, the other end of main gear reducer is connected with the input end of double-speed motor by hydraulic couplers, the lower end of secondary speed reducer is connected with input end of motor by coupling, and the pto＝power take-off of main gear reducer adopts expansion sleeve to be connected with the main shaft of xanthating machine.
Described main gear reducer adopts PHD9136 type, reduction speed ratio 38.55, allowable torque 550kN.m, service factor 1.3; Main gear reducer configuration double-speed motor 160kW 1450r/min, 110kW 960r/min, corresponding main gear reducer power output shaft speed is respectively 24.9r/min, 37.6r/min.
Described secondary speed reducer adopts PHD9075 type, reduction speed ratio 12.54, allowable torque 47kN.m, service factor 4.3; Secondary speed reducer configuration motor 132kW 1450r/min, corresponding main gear reducer power output shaft speed 3.0r/min.
FB270 type free wheel device selected by described free wheel device, need use moment of torsion 40kN.m.
Principle of the present utility model is: when combined speed reducer needs 3.0r/min to export, and starts 132kW speed reducer, i.e. secondary speed reducer; The 110kW 960r/min motor in double-speed motor is started when combined speed reducer needs 24.9r/min to export; The 160kW 1450r/min motor in double-speed motor is started when combined speed reducer needs 37.6r/min to export.
When double-speed motor starts, because speed discrepancy transmission is by total dynamic interruption, namely secondary speed reducer part is thrown off automatically, does not operate.When the machine operation that secondary speed reducer connects, free wheel device is in sync state, namely drives the input shaft run-in synchronism of main gear reducer.
The utility model has following beneficial effect:
1, this speed reducer moment of torsion is 550 kN.m, and little speed reducer 28 kN.m comparatively pass by has had and increases substantially.
2, adopt two standard speed reducer patterns, speed reducer is produced by famous foreign brand, and quality is more guaranteed, adds the interchangeability of spare part simultaneously.
3, free wheel device becomes separate unit, if easily damaged parts free wheel device breaks down, only need change clutch body, need not tear whole speed reducer open, overhaul more convenient, can avoid changing other gears causes waste simultaneously.
4, rate of fault significantly reduces, originally the maintenance in use needing more than twice every year of structure, and existing structure only needs conventional maintenance, never fault occurs up to now.
