Problems solved by technology

Although these assemblies enable some form of load sharing by delaying the engagement of the inner 18 and outer 24 races of the clutch 16, the assemblies require costly modifications to the support structure 39
Also, the assembly provides no means for sensing or releasing the load or tension on the clutch 16

Embodiment Construction

[0023] Referring now to the drawings, wherein like reference numerals are used to identify like parts throughout the several views, image 3 One embodiment of a torque arm assembly 40 according to the present invention is shown. Assembly 40 is configured to inhibit rotation of an outer race of a backstop clutch, such as outer race 24 of clutch 16 (see figure 2 ), and absorbs the load applied to the clutch 16 when the clutch 16 prevents reverse rotation of the motor drive shaft. Assembly 40 includes head member 42 , arm member 44 and strut 46 . Assembly 46 may also include a damper 48 .

[0024] Head member 42 is provided to engage outer race 24 of clutch 16 and the remainder of assembly 40 . Element 42 includes first and second clutch attachment plates 50 , 52 and an arm attachment plate 54 . Although the plates 50, 52, 54 are shown in the drawings as separate elements, it should be understood that the plates 50, 52, 54 could be integrated to form a unitary structure.

Abstract

Various torque arm assemblies for a backstopping clutch (16) are provided that enable load sharing among multiple torque arm assemblies, controlled release of load on the torque arm assembly and / or load sensing. The torque arm assembly includes a head member (42) that is connected to an outer race of a backstopping clutch and defines a pair of attachment points (72, 74). One end of an arm member (44) is pivotally connected to one attachment point of the head member while the other end of the arm member is connected to a stationary structure. A strut (46) extends between the other attachment point of the head member and the arm member. Upon backstopping action in one embodiment, the head member rotates slightly against the force of the strut allowing other torque arm assemblies to receive aportion of the system load. The position of the strut may be adjustable to allow controlled release of the load tension.

Description

technical field [0001] The present invention relates to torque arm assemblies for backstop clutches, and more particularly to enabling load distribution among multiple backstop assemblies within a larger system and / or allowing controlled release of loads or loads on the backstops. Tension torque arm assembly. Background technique [0002] In many motor-driven systems, it is desirable to prevent or limit movement of system components in one direction. For example, and referring to figure 1 , mining operations typically use an inclined conveyor mechanism 10 to convey material 12 to a surface location or other outlet. It is desirable to prevent or limit reverse movement of the conveyor mechanism 10 in the event of a loss of power or failure of a drivetrain component such as the motor 14, gearbox, or coupling, to prevent material 12 from moving back on the conveyor mechanism 10 and causing system failure. damage and significant injury to personnel operating the system.
