Abstract
The invention relates to a speed increasing brake device which is characterized in that a machine shell is provided with a center hole which is internally provided with a braked shaft that is provided with a big gear; the machine shell is internally provided with a small gear shaft meshed with the big gear; one end of the small gear shaft and one end of the braked shaft extend outside the machine shell; and the machine shell is provided with an electromagnetic brake connected with the outer end of the small gear shaft. By gear transmission, the lower speed of a braked body is converted into higher speed, the brake moment of the braked body is reduced, and the electromagnetic brake can be used for braking the big braked body; in addition, the brake is sealed inside a box body, so that the speed increasing brake device has high protection level, is suitable for various environments (especially suitable for the environment with the special requirements of corrosion prevention, anti-explosion and the like), solves the problems of large volume, easy abrasion and unstable braking force, and improves the braking effect; and furthermore, the speed increasing brake device has the advantages of simple and compact structure, reliable operation, stable performance, low cost and long service life.
Description
Technical field
The present invention relates to a kind of speed increasing brake device.
Background technology
Brake equipment is usually used in the reel braking of the hoisting wirerope of hoisting crane, elevator, recreation facility etc.The brake device structure of known hoisting wirerope reel is: the axle mounting of reel is on bracing frame, the brake disc that it is 1m that the other end of axle is equipped with a diameter, the brake disc both sides are equipped with baroque brake system, and this brake system is fixing separately in the brake disc side.This brake equipment greatly can't integral protection because of its volume under particular surroundings such as anticorrosion, explosion-proof, serious wear, braking force problem of unstable usually occur, also has the shortcoming that manufacturing cost height, volume are big, inconvenience is installed in addition.
Summary of the invention
The present invention provides a kind of speed increasing brake device of simple and compact for structure, good braking effect for solving the technical matters that exists in the known technology.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
A kind of speed increasing brake device, comprise the casing of being with centre hole, be installed in the casing centre hole be braked axle, be installed in the big gear wheel that is braked on the axle, be installed in the casing with big gear wheel ingear pinion shaft, pinion shaft one end and be braked the axle one end all stretch out outside the casing, be equipped with on the described casing and pinion shaft outer end bonded assembly magnet stopper.
The present invention can also adopt following technical scheme:
Described magnet stopper has a circular shell that is installed on the chassis sidewall, be movably installed with in the housing and miniature gears axle head key bonded assembly brake disc, the outside of brake disc is movably installed with coaxial platen, is equipped with to drive electromagnet and the pressure spring that platen moves in housing.
Advantage and good effect that the present invention has are:
Owing to be equipped with on the axle and pinion shaft ingear big gear wheel being braked, on the miniature gears axle head, magnet stopper is installed, by gear transmission the low speed that is braked body is transferred at a high speed like this, reduce the lock torque that is braked body, brake the big body that is braked with magnet stopper, this drg is sealed in the casing in addition, the protection level height, be fit to various environment (being particularly suitable for the environment of specific (special) requirements such as anticorrosion, explosion-proof), solved that volume is big, easy to wear, the braking force problem of unstable, improved braking effect; The present invention also has simple and compact for structure, reliable, smooth performance, cost is low, the life-span is long advantage in addition.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an A-A cutaway view among Fig. 1.
Among the figure: 1, reel; 2, casing; 3, housing; 4, be braked axle; 5, big gear wheel; 6, pinion shaft; 7, brake disc; 8, platen; 9, pressure spring; 10, electromagnet; 11, lid.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1 and Figure 2, casing 2 has centre hole, in the casing centre hole, be equipped with and be braked axle 4, being braked axle one end stretches out outside the casing, be braked the reel 1 that an external part is equipped with steel rope, be braked a inner big gear wheel 5 is installed, in casing, be equipped with and big gear wheel ingear pinion shaft 6, pinion shaft one end stretches out outside the casing, is equipped with on casing and pinion shaft outer end bonded assembly magnet stopper.Described magnet stopper has a circular shell 3 that is installed on the chassis sidewall, be movably installed with in the housing and miniature gears axle head key bonded assembly brake disc 7, the outside of brake disc is movably installed with coaxial platen 8, is equipped with to drive electromagnet 10 and the pressure spring 9 that platen moves in housing.Hull outside is equipped with openable lid 11, is convenient to install and maintenance.Like this, by gear transmission the low speed that is braked body is transferred at a high speed, thereby reduce the lock torque that is braked body, available magnet stopper is braked the big body that is braked, this drg is sealed in the casing in addition, and the protection level height is fit to various environment (being particularly suitable for the environment of specific (special) requirements such as anticorrosion, explosion-proof), solved that volume is big, easy to wear, the braking force problem of unstable, improved braking effect; The present invention also has simple and compact for structure, reliable, smooth performance, cost is low, the life-span is long advantage in addition.
