Those skilled in the art are to be understood that, the controllable pressure formula braking thread discharge disk provided in the utility model embodiment possesses automatic brake functions, it adopts pressure technology can realize stretching along brake facing or shrinking and realizes the brake operating of thread discharge disk, very easy to use.
Concrete structure and the concrete technique effect of the controllable pressure formula braking thread discharge disk provided the utility model embodiment below do detailed description:
In the concrete structure of the new axle system of the utility model, described axle 10 is 45# round steel framing member with described axle sleeve 11.
Preferably, can embodiment as one, described axle 10 is 0.05m with the right alignment that coordinates of described axle sleeve 11.
It should be noted that, in order to ensure that wire tray operates steadily, rotate flexible design and adopt three dish bearings, the bearing selected by Force Calculation analysis is: be respectively two dish deep groove ball bearings and a dish pressure ball bearing.Axle 10 upper end and axle 10 lower end adopt the first deep groove ball bearing 8, second deep groove ball bearing 14 of 60 series respectively, are used for bearing the capsizing moment in wire tray rotary course, ensure the right alignment of axle 10 and axle sleeve 11, thus reach rotation pulsation-free object.In addition, dish 51 serial thrust ball bearings 15 are arranged in axle 10 lower end, are used for bearing the weight of whole dish steel wire, reach the flexible pulsation-free object of revolution.
It should be noted that, deep groove ball bearing is a type the most common in antifriction-bearing box.Deep groove ball bearing substantial radial load, also can bear radial weight and axial load simultaneously.It can bear larger axial load, and the friction coefficient of deep groove ball bearing is very little, and limit speed is also very high.It also has other bearing characteristicses: such as: deep groove ball bearing is the representational antifriction-bearing box of most, of many uses.Be applicable to the even extremely high-revolving operation of high rotating speed, and very durable, without the need to frequent maintenance.Such bearing friction coefficient is little, and limit speed is high, and structure is simple, and low cost of manufacture, easily reaches higher accuracy of manufacture.Deep groove ball bearing is a most widely used class bearing in mechanical industry.Mainly bear Radial load, also can bear a certain amount of axial load.
Deep groove ball bearing is contained in after on axle, within the scope of the end-play of bearing, can the longitudinal travel of restrictive axes or shell both direction, and therefore can make axial location two-way.In addition, this class bearing also has certain aligning ability, when relative to shell aperture inclination 2 ' ~ 10 ', still can normally work.
Deep groove ball bearing is the most frequently used antifriction-bearing box.Its structure is simple, easy to use.Be mainly used to bear radial weight, but when increasing bearing end-play, there is the performance of certain angular contact ball bearing, footpath, axial connected load can be born.Therefore, the first deep groove ball bearing in the utility model embodiment and the second deep groove ball bearing can adapt to larger intensity pressure, ensure that it can play certain support pressure-bearing effect, ensure the right alignment of axle and axle sleeve, what ensure axle system stablizes steady rotating operation.
Thrust ball bearing (i.e. pressure bearing) is the abbreviation of axle pressure bearing, bears axial force.Add lubricating oil, thus increase bearing life.Thrust ball bearing adopts the design can bearing thrust load during high-speed operation, and it is owing to can bear stronger axial load, and therefore it can support the weight of whole dish steel wire.
Preferably, can embodiment as one, described axle sleeve 11 is welded and fixed with the top chock 9 of its upper end of axle sleeve 11 and the step 13 of lower end respectively.
Preferably, can embodiment as one, the bottom of described controllable pressure formula braking thread discharge disk is also provided with the channel steel base 1 of the square frame-shaped for supporting whole controllable pressure formula braking thread discharge disk; Described axle 10 is weldingly fixed in the centre hole of described channel steel base 1;
