Abstract
The invention relates to a large-torque overload clutch, which is characterized in that: the outer circle of a positioning sleeve is provided with a slotted hole which is perforated inside and outside; when the positioning sleeve is arranged on the outer circle of an inner sleeve after passing through the inner circle of the positioning sleeve; the slotted hole on the positioning sleeve is aligned with a semicylindrical pit on the inner sleeve; a pin roller is arranged in the semicylindrical pit on the outer circle of the inner sleeve through the slotted hole on the positioning sleeve; a floating pressure block is arranged in the slotted hole of the outer circle of the positioning sleeve; a spring is arranged in the slotted hole above the floating pressure block; and the outer sleeve and the positioning sleeve are fixedly arranged through a key.
Description
Technical field
The present invention relates to a kind of clutch, particularly a kind of high pulling torque overload clutch belongs to the component of machine technical field.
Background technique
In many machine driven systems, exert oneself the machine security accident that causes owing to torque overload in order to keep away, the mounting torque overload clutch generally all is set in its transmission system.At present, the overload clutch that is used for safety protection mainly contains friction type and mechanical type, and wherein there is complex structure in the overload clutch of friction type, and rate of fault is high, the defective that installation and maintenance trouble and cost are higher.Mechanical overload clutch, wherein, the overload clutch of steel ball type exists the moment of torsion that can transmit less owing to depend on the steel ball transmitting torque, the unsuitable defective that is applied to big machinery.Though and the moment of torsion that shear pin formula overload clutch can transmit is bigger, can adapt to the needs of main equipment; Because the principle of its protection is the destruction that relies on shear pin, reach other important purpose of parts in addition of protection, because Shear Cut Pin is in case destroy; Want the normal function of restorer must make the installation Shear Cut Pin again; So there is the use trouble in the overload clutch of Shear Cut Pin formula, the shortcoming that service cycle is long.
Summary of the invention
The objective of the invention is to: a kind of high pulling torque overload clutch is provided, overcomes the existing existing above-mentioned defective of overload clutch.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of high pulling torque overload protection clutches; It is the slotted hole that is interlinked to the outside on the cylindrical of setting sleeve, having; To work as setting sleeve be installed in through circle in it in above the cylindrical of cover the time, with the slotted hole on the setting sleeve with in the semi-cylindrical pit that puts align, roller is through the slotted hole on the setting sleeve; In the semi-cylindrical pit in being installed on the cover cylindrical; Unsteady briquetting is installed in the slotted hole of setting sleeve cylindrical, in the slotted hole above the briquetting that floats spring is housed, and overcoat installs and fixes together through key and setting sleeve.
Beneficial effect: the present invention realizes the transmission of moment of torsion owing to adopt the way of agreeing with each other between roller and interior cover and the setting sleeve, so, not only have the function of overload protection, simultaneously, have the bigger advantage of transmitting torque.
