Abstract
The invention relates to a chain wheel overload protective device, which comprises a driving shaft, a shaft sleeve, a chain wheel and an overload protection mechanism, wherein the shaft sleeve is arranged and fixed at the end part of the driving shaft, and the chain wheel is sleeved on the shaft sleeve. The chain wheel overload protective device is characterized in that: the overload protection mechanism comprises a bent safety slot, a metal spring piece, a safety pin and an alarm switch; the bent safety slot is fixedly arranged at the end part of the driving shaft; the tail end of the metal spring piece is fixed at the end part of a stay bolt on the lateral surface of the chain wheel; the metal spring piece bends elastically, the head end of the metal spring piece is placed in the bent safety slot, and the metal spring piece runs synchronously with the chain wheel; the chain wheel and the shaft sleeve are connected with each other through the safety pin and rotate together, and the tail end of the safety pin is provided with a limiting clip for preventing the safety pin from being pulled out; and the alarm switch is positioned in front of the driving shaft and is next to the metal spring piece, and the metal spring piece is contacted with the alarm switch in a free state. The chain wheel overload protective device has the advantages of simple and reasonable structure, low cost, convenient manufacturing, safety and reliability.
Description
Technical field
The invention belongs to mechanical automation conveying technology field, specifically relate to a kind of chain wheel overload protective device.
Background technique
At present; in plate chain course of conveying; plate chain overload causes motor and other corollary equipments to damage; bring loss to production; in order to stop the generation of this situation; drive end at the plate chain just need be provided with an overload protection arrangement, when occurring in time reporting to the police and realize motor idle running when fortuitous event causes overload or plate chain stuck phenomenon, is not damaged with protection equipment.Overload protection arrangement of the prior art is complex structure often, complex operation, and fabricating cost is higher, is not suitable for promoting the use of on a large scale.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of simple and reasonable, with low cost, easily manufactured and safe and reliable chain wheel overload protective device is provided.
Purpose of the present invention realizes by following technological scheme: described chain wheel overload protective device comprises transmission shaft, axle sleeve, sprocket wheel and overload protecting mechanism, axle sleeve is installed in transmission shaft end and fixing, sprocket wheel is sleeved on the axle sleeve, it is characterized in that: described overload protecting mechanism comprises bending shape safety groove, metal clips, safety pin and alarm switch, bending shape safety groove is fixedly mounted on the transmission shaft end, the metal clips tail end is fixed on the stay bolt end on the chain wheel side, the metal clips elastic bending, its head end places in the described bending shape safety groove, metal clips and sprocket wheel run-in synchronism; Described sprocket wheel and axle sleeve connect by safety pin, rotate synchronously, and the safety pin tail end is equipped with the spacing card that prevents that it from deviating from; Alarm switch is positioned at transmission shaft the place ahead and is close to metal clips, and metal clips contacts with alarm switch after breaking away from bending shape safety groove.
As a further improvement on the present invention, described safety pin is the middle round metal pin that has grooving, to improve Safety performance.
As a further improvement on the present invention, the width of described metal clips reduces gradually along tail end head-end direction, and the tail end of broad makes it more firm with being connected of stay bolt; Narrower head end makes it detach bending shape safety groove soon at the Shi Nenggeng that goes wrong, and reports to the police.
The present invention is simple and reasonable, and manufacturing process is simple, with low cost, when sprocket wheel transships, and shear pin breakage, axle sleeve and sprocket wheel break away from rotation synchronously, and metal clips breaks away from bending shape safety groove, touches alarm switch, finishes overload protection and warns, and is safe and reliable.

Description of reference numerals: 1-stay bolt, 2-alarm switch, 3-metal clips, 4-bending shape safety groove, 5-pressing plate, 6-axle sleeve, 7-safety pin, the spacing card of 8-, 9-sprocket wheel, 10-grooving, 11-bearing support, 12-transmission shaft, 13-bearing.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, the present invention mainly is made up of transmission shaft 12, axle sleeve 6, sprocket wheel 9, bearing support 11, bearing 13 and overload protecting mechanism, and overload protecting mechanism is made up of bending safety groove 4, metal clips 3, safety pin 7 and alarm switch 2.
As shown in Figure 1 and Figure 2, transmission shaft 12 is installed on the bearing support 11 by bearing 13, axle sleeve 6 is installed in transmission shaft 12 ends and is fixedly linked by pressing plate 5 and key, sprocket wheel 9 is sleeved on the axle sleeve 6, all offer pin-and-hole on sprocket wheel 9 and the axle sleeve 6, safety pin 7 passes sprocket wheel 9 and axle sleeve 6 connects the two, and safety pin 7 tail ends are equipped with the spacing card 8 that prevents that it from deviating from, spacing card 8 is by being bolted on sprocket wheel 9 sides, and sprocket wheel 9 and axle sleeve 6 rotate synchronously; Bending shape safety groove 4 is installed on the pressing plate 5 of transmission shaft 12 ends by bolt, metal clips 3 tail ends are fixed on stay bolt 1 end by nut screwing clamping, stay bolt 1 the other end is fixed on sprocket wheel 9 sides, metal clips 3 elastic bendings, its head end places in the described bending shape safety groove 4, metal clips 3 and sprocket wheel 9 run-in synchronisms; Alarm switch 2 is positioned at transmission shaft 12 the place aheads and is close to metal clips 3, and metal clips 3 contacts with alarm switch 2 after breaking away from bending shape safety groove 4.
As shown in Figure 3, have the round metal pin of grooving 10 in the middle of safety pin 7 preferred employings the among the present invention, to improve Safety performance.
As shown in Figure 2, the width of described metal clips 3 reduces gradually along tail end head-end direction, and the tail end of broad makes it more firm with being connected of stay bolt 1; Narrower head end makes it detach bending shape safety groove 4 soon at the Shi Nenggeng that goes wrong, and reports to the police.
In concrete the application, when sprocket wheel 9 did not transship, sprocket wheel 9 and axle sleeve 6 were because the effect of safety pin 7 realizes run-in synchronism, and the head end of metal clips 3 is positioned at bending shape safety groove 4 all the time, can't touch alarm switch 2, and equipment runs well.When sprocket wheel 9 transshipped or stuck situation occurs, from grooving 10 fractures, sprocket wheel 9 separated with axle sleeve 10 safety pin 7 owing to bear excessive torque, no longer run-in synchronism, and driving arrangement is protected in transmission shaft 12 idle running effectively; Simultaneously, metal clips 3 detaches in bending shape safety groove 4, because elastic reaction touches alarm switch 2, realizes warning function.
