Description
Technical field
The utility model relates to roll brake technical fields, more specifically refer to a kind of non-self-lock-ing worm and gear braking
Device.
Background technique
The pre- planishing roll case of Gao Xian factory is using worm and gear as roll-separating mechanism.Due to the spiral for using self-locking performance poor
Lift angle, worm gear can make worm screw generate rotary motion, eventually lead to roll gap size and change in the case where stress in the operation of rolling
Become, generates substandard product.
The worm and gear of current pre- planishing roll case brakes it using hydraulic disc brake formula.But the braking of hydraulic disc brake formula belongs to
It is braked in normal pressure state, there are the following aspects defects: 1, causing brake shelf to deform due to being pressurized for a long time, accelerate it
Aging；2, piling of steel can occur for the operation of rolling, and connected pipes is caused to be burnt, and oil is largely lost, and roll is lost the job performance, seriously
When there are also occur fire possibility；3, hydraulic disc brake formula brake is bulky, is not easy replacement and maintenance；4, hydraulic disc brake formula system
It moves and is suppressed for circumference single-point, insensitivity is poor.Therefore, we provide a kind of non-self-lock-ing worm and gear brake.
Summary of the invention
The utility model provides a kind of non-self-lock-ing worm and gear brake, to solve the hydraulic disc brake of roll-box worm and gear
Formula braking insensitivity difference and brake shelf be pressurized for a long time it is easy to aging, brake it is bulky it is not easy to repair with maintenance with
And piling of steel causes pipeline leak and the problems such as there are security risks in the operation of rolling.
The utility model adopts the following technical solution:
A kind of non-self-lock-ing worm and gear brake, including flange, spline housing, seal closure, brake ring, tooth set, tabletting and electricity
Magnetic brake, the seal closure offer an accommodation groove, and the fixed seal closure side of the inner face of the flange will be described
Accommodation groove sealing, the outer end face of the flange are fixedly connected on roller case, and the spline housing, which coaxially runs through, to be arranged in the flange
Portion, wherein exposing the spline housing outer end outside the seal closure, to be set in outer diameter compatible with the spline housing internal diameter
Roller case is adjusted on the outer peripheral surface of worm screw, and the spline housing inner end inside the seal closure is fixed with the tooth
Set, the tooth set outer peripheral surface engagement connect the brake ring, and the side of the brake ring is resisted against the inner face of the flange,
The other side is equipped with a tabletting, and the tabletting another side wall side opposite with brake ring is additionally provided with the electromagnetism
Brake is equipped with spring between the electromagnetic brake and the tabletting.
Further, the inner sidewall of the tooth set is connect by key with the lateral wall of the spline housing inner end.
Further, the spline housing and tooth set are coaxially positioned by snap ring.
Further, the seal closure side is bolted to connection the inner face in the flange.
By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent
Point:
The spline housing of the utility model is covered by tooth to be connect with brake ring, and roller case is adjusted worm screw by spline housing and is drawn
Flange.When electromagnetic brake no power, tabletting compresses brake ring.After energization, tabletting is sucked by electromagnetic brake, brake ring
No longer stress, brake ring moves in a circle that worm screw is driven to move in a circle at this time, realizes roll gap adjustment.
The utility model is additionally provided with a seal closure, which seals entire electromagnetic brake and brake ring, can
To play the role of waterproof.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
A kind of non-self-lock-ing worm and gear brake, referring to Fig.1, including flange 1, spline housing 2, seal closure 3, brake ring 4, tooth
Set 5, tabletting 6 and electromagnetic brake 7.Seal closure 3 offers an accommodation groove 31, and the inner face of flange 1 is fixed on by bolt 8
3 side of seal closure seals accommodation groove 31.The outer end face of flange 1 is fixedly connected on roller case, and spline housing 2 coaxially exists through setting
1 middle part of flange.Wherein, 2 outer end of spline housing outside exposing seal closure 3 is set in outer diameter and mutually fits with 2 internal diameter of spline housing
The roller case matched is adjusted on the outer peripheral surface of worm screw.2 inner end of spline housing inside seal closure 3 is fixed with a tooth set 5, flower
Key set 2 and tooth set 5 are coaxially positioned by snap ring 9.The inner sidewall of tooth set 5 is connect by key 10 with the lateral wall of spline housing 2, tooth set
5 outer peripheral surfaces engagement connection brake ring 4.The side of the brake ring 4 is resisted against the inner face of flange 1, and the other side is equipped with a pressure
Piece 6, another the side wall side opposite with brake ring 4 of tabletting 6 are additionally provided with an electromagnetic brake 7, the electromagnetic brake 7 and pressure
Spring 11 is equipped between piece 6.
Referring to Fig.1, when electromagnetic brake 7 is not powered in the operation of rolling, tabletting 6 pushes down brake ring 4 under the effect of spring 10
So that 4 stress of brake ring is without moving in a circle, i.e., worm and gear will not generate rotary motion and make roll gap size variation.It is powered
After, tabletting 6 is sucked in electromagnetic brake 7, at this time the no longer stress of brake ring 4 and start to move in a circle, brake ring 4 passes through tooth
Set 5 and spline housing 2 drive the roller case being set in spline housing 2 to adjust worm screw and move in a circle together, that is, realize the adjusting of roll gap.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept should belong to the row for invading scope of protection of the utility model
For.
