Abstract
The utility model discloses a safety clutch. An intermediate gear (4) is installed on a clutch gear shaft (1). Brake block assemblies (3) are respectively installed at two ends of the clutch gear shaft (1) disposed on the intermediate gear (4). Belleville springs are respectively installed at two ends of the clutch gear shaft (1) disposed on the brake block assemblies (3). The left Belleville spring is positioned through a compressing sleeve (6) which is installed on the clutch gear shaft (1). A deep groove ball bearing (7) is disposed on the outer side of the compressing sleeve (6) installed on the clutch gear shaft (1). A separating bushing (8) is arranged on the clutch gear shaft (1) and on the outer side of the deep groove ball bearing (7) through an O-shaped ring (10). A metal insert locknut (9) is installed on the clutch gear shaft (1) and on the outer side of the separating bushing (8). As a result, the safety clutch is integrally formed. The safety clutch is simple in structure and convenient to operate, and carries out protection for an electric hoist when overloading occurs or a limit switch is damaged.
Description
Technical field
The utility model relates to the Hoisting Machinery field, relates in particular to the safety installations of Electric Chain Blocks.
Background technique
As everyone knows; Safety clutch is the requisite safety protection device of Electric Chain Blocks, but at present, the Electric Chain Blocks safety protection device on the market generally is the limit stoper up and down of control cucurbit; And be the limit function that cucurbit rises or drops to limit position; Still there is certain safety issue, damages, because of suspension hook and chain the bump of Electric Chain Blocks body is caused the damage of component in the body easily like limit switch.
Summary of the invention
The purpose of the utility model is: a kind of safety clutch is provided; Be that the overload of a kind of may command is when damaging back cucurbit rising or dropping to limit position with limit switch; It is intermediate gear rotation and the clutch teeth axle does not change that safety clutch skids, to the protective gear of electric wire hoist.
The technical solution of the utility model is: this safety clutch comprises clutch teeth axle, belleville spring, brake disc assembly, intermediate gear, sliding sleeve, clamping sleeve, deep groove ball bearing, spacer and metal insert locking nut; On the clutch teeth axle, intermediate gear is installed through sliding sleeve; Brake disc assembly is installed at the two ends that on the clutch teeth axle, are positioned at intermediate gear respectively; Belleville spring is installed at the two ends that on the clutch teeth axle, are positioned at brake disc assembly respectively; The right side belleville spring is by the step location of clutch teeth axle; The left side belleville spring compresses the location by the clamping sleeve that is installed on the clutch teeth axle, and deep groove ball bearing is installed in the outside of clamping sleeve on the clutch teeth axle, and spacer is installed through O type circle in the outside at deep groove ball bearing on the clutch teeth axle; The metal insert locking 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 the sprocket wheel; When Electric Chain Blocks was worked, motor shaft drove the intermediate gear running, and intermediate gear drives the running of clutch teeth axle, and the clutch teeth axle drives the output gear running, and output gear drives the sprocket wheel running; When cucurbit hangs thing when overweight or limit switch when damaging, it is intermediate gear rotation and the clutch teeth axle does not change that safety clutch skids, thereby the protection gear can not damage.
The utlity model has following advantage: 1, simple in structure, easy to operate, when overload or limit switch damage, electric wire hoist is protected, increase the service life, reduce maintenance expenses; 2, O type circle is used for preventing that gear oil from leaking outside, and the metal insert locking nut is regulated safety clutch, and is rational in infrastructure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 clutch teeth axle, 2 belleville springs, 3 brake disc assemblies, 4 intermediate gears, 5 sliding sleeves, 6 clamping sleeves, 7 deep groove ball bearings,
8 spacers, 9 metal insert locking nuts, 10 O type circles.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1; This safety clutch comprises clutch teeth axle 1, belleville 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 locking nut 9; On clutch teeth axle 1, intermediate gear 4 is installed through sliding sleeve 5; Brake disc assembly 3 is installed at the two ends that on clutch teeth axle 1, are positioned at intermediate gear 4 respectively; Belleville spring 2 is installed at the two ends that on clutch teeth axle 1, are positioned at brake disc assembly 3 respectively, and the right side belleville spring is by the step location of clutch teeth axle 1, and the left side belleville spring compresses the location by the clamping sleeve 6 that is installed on the clutch teeth axle 1; Deep groove ball bearing 7 is installed in the outside of clamping sleeve 6 on the clutch teeth axle 1; Spacer 8 is installed through O type circle 10 in the outside at deep groove ball bearing 7 on the clutch teeth axle 1, and metal insert locking nut 9 is installed in the outside at spacer 8 on the clutch teeth axle 1, whole formation safety clutch.
During installation, the right-hand member of clutch teeth axle 1 connects output gear on the sprocket wheel; When Electric Chain Blocks was worked, motor shaft drove 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, and output gear drives the sprocket wheel running; When cucurbit hangs thing when overweight or limit switch when damaging, safety clutch skids, thereby the protection gear can not damage.
