Abstract
In some examples, a ball nut includes a first end and an outer cylindrical surface having a first diameter. A pulley may be mounted on the first end of the ball nut. The pulley may include an inner cylindrical surface having a second diameter larger than the first diameter of the ball nut and sized to engage with the outer cylindrical surface in a press fit. Furthermore, a circumferential groove may be formed in a portion of the first end of the ball nut extending beyond the pulley when the pulley is mounted on the first end of the ball nut. A retaining ring is disposed in the circumferential groove to prevent removal of the pulley from the first end of the ball nut. Furthermore, a portion of the ball nut may engage with a portion the pulley to prevent relative rotation between the pulley and the ball nut.
