Abstract
The invention discloses a safety clutch. An intermediate gear (4) is mounted on a clutch gear shaft (1). A brake pad assembly (3) is mounted at two ends of the intermediate gear (4) on the clutch gear shaft (1). Disc springs (2) are mounted at two ends of the brake pad assembly (3) on the clutch gear shaft (1). The left disc spring is positioned through a compressing sleeve (6) on the clutch gear shaft (1). A deep groove ball bearing (7) is mounted outside the compressing sleeve (6) on the clutch gear shaft (1). Through an O-shaped ring (10), a spacer (8) is mounted outside the deep groove ball bearing (7) on the clutch gear shaft (1). A metal embedded locknut (9) is mounted outside the spacer (8) on the clutch gear shaft (1). Therefore, the safety clutch is formed. The safety clutch is simple in structure and convenient to operate, and can protect an electric hoist when overloading or limit switch damage occurs.
Description
Technical field
The present invention relates to the elevator machinery field, relate in particular to the safety device of Electric Chain Blocks.
Background technology
As everyone knows; safety clutch is the requisite safety guard of Electric Chain Blocks; but at present; Electric Chain Blocks safety guard on market is generally the inhibiting device up and down of controlling cucurbit; and be the limit function that cucurbit rises or drops to end position; still there is certain safety issue, as limit switch damages, easily because of suspension hook and chain, the shock of Electric Chain Blocks body is caused to the damage of parts in body.
Summary of the invention
The object of the invention is to: a kind of safety clutch is provided; be a kind of control overload and limit switch and damage after cucurbit rising or while dropping to end position; it is intermediate gear rotation and the clutch teeth axle does not turn that safety clutch skids, to the fender guard of electric block.
Technical solution of the present invention is: this safety clutch comprises the clutch teeth axle, disk spring, brake disc assembly, intermediate gear, sliding sleeve, clamping sleeve, deep groove ball bearing, spacer and metal insert jam nut, through sliding sleeve, intermediate gear is installed on the clutch teeth axle, brake disc assembly is installed respectively at the two ends that are positioned at intermediate gear on the clutch teeth axle, disk spring is installed respectively at the two ends that are positioned at brake disc assembly on the clutch teeth axle, the right side disk spring is by the step location of clutch teeth axle, the left side disk spring compresses location by the clamping sleeve be arranged on the clutch teeth axle, on the clutch teeth axle, deep groove ball bearing is installed in the outside of clamping sleeve, spacer is installed through O type circle in the outside at deep groove ball bearing on the clutch teeth axle, the metal insert jam nut is installed in the outside at spacer on the clutch teeth axle, whole formation safety clutch.
During installation, the right-hand member of clutch teeth axle connects output gear on sprocket wheel; When Electric Chain Blocks is worked, motor shaft drives the intermediate gear running, and intermediate gear drives the running of clutch teeth axle, and the clutch teeth axle drives the output gear running, the running of output gear band movable sprocket; When cucurbit hangs thing when overweight or limit switch while damaging, it is intermediate gear rotation and the clutch teeth axle does not turn that safety clutch skids, thereby the protection gear can not damage.
The present invention has the following advantages: 1, simple in structure, easy to operate, when overload or limit switch damage, electric block is protected, and increase the service life, reduce service expenditure; 2, O type circle is used for preventing that gear oil from leaking outside, and the metal insert jam nut is regulated safety clutch, rational in infrastructure.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 clutch teeth axle, 2 disk springs, 3 brake disc assemblies, 4 intermediate gears, 5 sliding sleeves, 6 clamping sleeves, 7 deep groove ball bearings,
8 spacers, 9 metal insert jam nuts, 10 O type circles.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, this safety clutch comprises clutch teeth axle 1, disk spring 2, brake disc assembly 3, intermediate gear 4, sliding sleeve 5, clamping sleeve 6, deep groove ball bearing 7, spacer 8 and metal insert jam nut 9, through sliding sleeve 5, intermediate gear 4 is installed on clutch teeth axle 1, brake disc assembly 3 is installed respectively at the two ends that are positioned at intermediate gear 4 on clutch teeth axle 1, disk spring 2 is installed respectively at the two ends that are positioned at brake disc assembly 3 on clutch teeth axle 1, the right side disk spring is by the step location of clutch teeth axle 1, the left side disk spring compresses location by the clamping sleeve 6 be arranged on clutch teeth axle 1, on clutch teeth axle 1, deep groove ball bearing 7 is installed in the outside of clamping sleeve 6, spacer 8 is installed through O type circle 10 in the outside at deep groove ball bearing 7 on clutch teeth axle 1, metal insert jam nut 9 is installed in the outside at spacer 8 on clutch teeth axle 1, whole formation safety clutch.
During installation, the right-hand member of clutch teeth axle 1 connects output gear on sprocket wheel; When Electric Chain Blocks is worked, motor shaft drives intermediate gear 4 runnings, and intermediate gear 4 drives 1 running of clutch teeth axle, and clutch teeth axle 1 drives the output gear running, the running of output gear band movable sprocket; When cucurbit hangs thing when overweight or limit switch while damaging, safety clutch skids, thereby the protection gear can not damage.
