1. General

SBB365 safety disc brake (hereinafter briefly called brake) is mainly used as emergency brake at low speed shaft (driving output shaft) for various large and middle crane at main hoist and boom hoist mechanism and cable crane at driving mechanism, or service and emergency brake for mine winder lifter, obliquitous belt conveyor at driving mechanism.

The brake is applied by disc spring and released by hydraulic pressure oil，which structure is shown as Fig.1, and the principle of operation is following: When the hydraulic fluid flows into cylinder under solenoid valve controlling, the hydraulic fluid farther press the disc spring and push the piston rod to open the arms, then braking torque is eliminated; when the solenoid valve is powered off, the pressure oil will return to oil tank by the spring force acting, simultaneously the spring force through the piston rod and the arms acts on the disc, and then the rated torque is established.

2.1 Lifting and transportation

The brake must be lifted carefully in order to avoid damage, and must be lifted by using crane and lifting rope for its 686g weight. The lifting position show as fig-2. Prohibit from using other parts except lifting bolt to lift！

2.2 Preparation before installation

The brake must be installed correctly; otherwise, it will affect the design performance. So the users must comply with the manual strictly during installing. If need helps, please contact with our sales department.

2.2.1 check disc and brake：

a. Check if the nameplate parameters comply with requirement；

b. Check if have all parts；

c. If there is any corrosion and jamming at every pivot point；

d. Check if the lining surface have oil (grease) and other impurity which effect the performance； e. Check if the disc surface has rust, oil (grease) and damage due to welding, unevenness and other defects. Prohibit from using disc with crack or other serious defects.

If found abnormal situation, please install after dealing with it.

2.2.2 Check foundation and brake：

a. The foundation must be fixed and evenness;

b. The tolerance and surface roughness of the bracket refer to Fig.3.

2.3 Installation

2.3.1 Installing the bracket onto foundation

a. Clear the oil and dirt on the surface of foundation, and then lift the brake onto the foundation by crane.

b.Release adjustment nut (part 5, Fig.1), rotate clockwise the lock nut (part 1, Fig.1. see from the switch side) to open the arms, and ensure the distance between two linings is over 3mm than the thickness of disc.

c. Remove the opened brake to installing position, put on the foundation bolts, adjust the brake and make the edge of the lining retract about 3~5mm than outside diameter of the disc (refer to Fig.1).

d.Connect the limit switch cable (signal indication). The connection must be firmed in order to avoid accident due to the released cable. The switch cable entry stuffing is Pg13.5(3×1.5)。

2.3.2 Hydraulic pipeline connection and exhausting

a. Installing and adjusting hydraulic power unit well before installing the brake (please refer to the operator’s manual of hydraulic power unit), arrange the hydraulic pipeline. The oil entry thread of the brake cylinder is M18X1.5 (refer to Fig.1), the inside diameter of the pipeline must be over 10mm, and the entered oil volume is 270mL when the each side clearance of the brake is 2mm.

b. Exhaust air in the cylinder before operating and adjusting the brake, the method is: on the top of the cylinder there is exhaust and pressure gauge connector (part 9 in Fig.1). The thread of the connector is M16. When testing pressure, remove the cover and connect the pressure gauge accessory; when exhausting, remove the cover ring for anti-falling, screw the cover tightly (refer to Fig.4). After exhausting, replace the connector as delivery state.

2.4 Adjustment

2.4.1 All adjustment must be operated before first installing and after changing new lining. At first installing, please according to following steps:

a. The adjustment of clamping force: release the brake by electric control or manual-operated pump (refer to operator’s manual of hydraulic power unit), release the lock nut (part 1, Fig.1), and rotate the adju …… 此处隐藏：8935字，全部文档内容请下载后查看。喜欢就下载吧 ……
