Abstract
A torque-to-thrust apparatus includes a one-way mechanism permitting free application of rotation to torque. A friction plate disposed between a portion of a one-way device and a stationary member of the torque-to-thrust apparatus inhibits reverse rotation at a predetermined torque level, which will maintain the thrust member of the torque-to-thrust apparatus in an engaged condition until a predetermined load is applied to the rotary side of the torque-to-thrust apparatus to overcome the friction load.
Claims7
A torque-to-thrust apparatus including a one-way friction torque-transmitting mechanism comprising:
- a rotary input member operable in a forward and reverse direction;
- a linear output member;
- torque-to-thrust means disposed between said rotary input member and said linear output member for transmitting rotary motion of said input member to linear motion of said output member;
- a stationary component;
- a one-way torque-transmitting mechanism disposed adjacent said stationary component and being responsive to said rotary input member to permit free rotation in a first direction;
- a friction means disposed between said stationary component and a member of said one-way torque-transmitting mechanism to hold said one-way torque-transmitting mechanism member stationary to inhibit the reverse rotation of said rotary input member in a second direction until a predetermined rotary force is present at said rotary input member in said second direction.
