Abstract
The invention discloses a cone-type braking mechanism. The cone-type braking mechanism comprises a clutch, a stationary shaft, a left cone frustum and a right cone frustum connected with the stationary shaft, rotating wheels and sleeves, wherein the left cone frustum is fixedly connected with the stationary shaft; the right cone frustum is connected with the stationary shaft in a sliding way; the right cone frustum is contacted with the clutch; the contact part between the right cone frustum and the clutch has a sawtooth shape; the sleeves are arranged on the inclined surfaces which are matched with the conical surfaces of the left cone frustum and the right cone frustum; and the sleeves are contacted with the rotating wheels. By using the cone-type braking mechanism, the braking of the rotating wheels is realized by utilizing the inclined surfaces; the cone-type braking mechanism has a simple structure; the brake and the release can be realized by switching the rotating directions of the clutch; and the cone-type braking mechanism is convenient to operate.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of circular cone type arrestment mechanism.
Background technique
Arrestment mechanism is to have to make moving element or movable machinery slow down, stop or keeping the device of the functions such as halted state, is the mechanical parts that make the movement parts in the machinery stop or slowing down, and is commonly called as brake, lock; Arrestment mechanism applies certain active force by outer bound pair braking part position, apparatus to running applies and the external force that operates opposite direction, utilize non-rotating element and stop the trend of rotation or the rotation of wheel with phase mutual friction between the rotatable member, thereby it is carried out to a certain degree forced brake.Usually be contained on the high speed shaft of equipment in order to reduce a braking moment and structure cun break, but the main equipment higher to security requirement (such as mine hoist, elevator etc.) then is installed near on the lower velocity shaft of equipment working portion.
Mechanical operating part is stopped or the resisting moment that must apply of slowing down is called braking moment.Braking moment is design, selects the foundation of break that its size is determined by pattern and the job requirement of machinery.The performance of used friction material directly affects braking process on the break, and the principal element that affects its performance is operating temperature and temperature rise speed.Friction material should possess high and stable friction factor and good wear resistance.
Summary of the invention
The technical problem to be solved in the present invention provides circular cone type arrestment mechanism a kind of simple in structure, easy to operate.
In order to solve the problems of the technologies described above, the invention provides a kind of circular cone type arrestment mechanism, comprise clutch, stationary axle, the left and right circular cone, gyrostat and the sleeve that are connected with stationary axle, described left circular cone is fixedly connected with stationary axle, and right circular cone and stationary axle are slidingly connected; Right circular cone contacts with clutch, and its contact position is zigzag fashion; Be located at the inclined-plane that the conical surface with left and right circular cone is complementary on the sleeve; Sleeve contacts with gyrostat.
During braking, rotary clutch because zigzag fashion so that right circular cone is pressed to left circular cone, owing to be provided with conical inclined-plane between left and right circular cone and the sleeve, forces the outside distending of sleeve, contacts with gyrostat, produces friction torque so that gyrostat is braked; When unclamping, the opposite spin clutch is cancelled the extruding to right circular cone, so that sleeve away from gyrostat, is eliminated friction torque.This practicality newly realizes braking to gyrostat by the utilization to the inclined-plane, and is simple in structure, only needs can realize braking and unclamp the switching that clutch turns to when operation, easy to operate.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
As shown in Figure 1, the invention provides a kind of circular cone type arrestment mechanism, comprise half-clutch device 1, stationary axle 2, the left circular cone 4 that is connected with stationary axle 2 and right circular cone 3, gyrostat 5 and sleeve 6, described left circular cone 4 is fixedly connected with stationary axle 2, and right circular cone 3 is slidingly connected with stationary axle 2; Right circular cone 3 contacts with half-clutch device 1, and its contact position is zigzag fashion; Be located at the inclined-plane that the conical surface with left circular cone 4, right circular cone 3 is complementary on the sleeve 6; Sleeve 6 brake rotaries wheel 5.
During braking, half-clutch device 1 is chimeric mutually with zigzag fashion with right circular cone 3, rotation connects firmly the handle a on half-clutch device 1, because zigzag fashion, so that right circular cone 3 is pressed to left circular cone 4, owing to be provided with conical inclined-plane between left and right circular cone and the sleeve 6, force sleeve 6 outside distendings, contact with gyrostat 5, produce friction torque so that gyrostat 5 is braked; When unclamping, the half-clutch device 1 of opposite spin is cancelled the extruding to right circular cone 3, so that sleeve 6 away from gyrostat 5, is eliminated friction torque.
Above-described only is preferred implementation of the present invention, should be understood that for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
