Abstract
The utility model relates to a speed-increasing brake device, which is characterized in that: a shell is provided with a central hole, and a braked shaft is arranged in the central hole of the shell; a large gear is arranged on the braked shaft, and a pinion shaft meshed with the large gear is arranged in the shell; and one end of the pinion shaft and one end of the braked shaft extend out of the shell, and an electromagnetic brake connected with the outer end of the pinion shaft is arranged on the shell. Accordingly, the low speed of a braked body is converted into high speed by the transmission of a gear, a braking torque of the braked body is reduced, and a large braked body is braked by the electromagnetic brake; in addition, the brake is sealed in a box body, so the brake has high protective grade, is suitable for various environments (especially for anti-corrosion and explosion-proof environments and other environments with special requirements), solves the problems of large volume, easy wear and instable brake force, and improves the braking effect. In addition, the utility model also has the advantages of simple and compact structure, reliable operation, stable performance, low cost and long service life.
Description
Technical field
The utility model 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 utility model 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 utility model is taked 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 utility model 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 the good effect that the utlity model 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 utility model 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 utility model;
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 utility model, 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 utility model also has simple and compact for structure, reliable, smooth performance, cost is low, the life-span is long advantage in addition.
