Back Stop Clutch
1. KUDOSWORLD backstop is to prevent reverse rotation or smooth sliding of the inclined belt conveyor when it stops with load. Based on the calculation of the braking torque, the backstop or braking device is added according to the specific situation.
2. KUDOSWORLD backstop is suitable for belt conveyors with upward conveying and inclination ≤ 18 degrees. Its advantages are rapid backstop and small reverse distance. It is the preferred backstop for large and medium inclined conveyors. It is widely used in reducer matching, coking plant and transportation machinery, conveyors, hoists, electric rollers and other mechanical equipment requiring backstop requirements.

NF type contactless wedge non-return device technical parameters and installation dimensions
Description
NF type is the non-contact backstop, which is widely used in the design of transportation machinery and lifting machinery for mining, bulk material collection and lifting device. The internal structure of the new type wedge with optimized design is used, except for the great impact resistance and the large backstop moment. When the forward rotation speed of input shaft is higher than the minimum speed, the internal work can achieve no contact, zero wear and long service life.
NYD（NJ）contact wedge non-return device technical parameters and installation dimensions
Description
Model NYD is a low speed contact backstop, which is widely used in the belt conveying machinery industry, and is suitable for the occasions where the material lifting must be backstop. It has the advantages of compact structure, reliable backstop, easy release, convenient installation and strong applicability.
NDZ contact device technical parameters and installation dimensions
Description
NDZ contact backstop is a kind of low-speed anti reverse device, with bearing support, filter interface, oil mark and labyrinth lubrication channel. It has the advantages of compact, light weight, wedge fitting and low installation accuracy. It can be directly installed on the main engine roller or the reducer. It is a kind of protection device for lifting transportation equipment.
Compared with Nd type backstop, it has the advantages of high Overrunning Speed, large torque, high precision, long service life, safer and more reliable. It can be used for large angle conveyor, bucket elevator and other equipment with backstop requirements
Note:
1.The hole tolerance is H7, the recommended shaft tolerance is h6, the keyway according to GB/T1095-1979, grade 7-9 standard production from GB/T1184-1996. General key connection is used for width deviation, the shaft is N9 and the hub is Js9.
2.The axial position of the moment arm can not be rigid, so that the moment arm can move axially to prevent the additional moment caused by the misalignment of the shaft. The pin or angle iron can be used for circumferential positioning, and the circumferential iron can not be tilted, otherwise the backstop will fail. 3.NJZ represents the standard code of coal industry
