Abstract

A worm drive system is provided. The worm drive system having: a motor for rotating a worm, the worm having a bearing surface rotatably received by a bearing surface integral with a housing the worm is located in, wherein a lubrication reservoir is located proximate to the bearing surface of the worm such that lubricants located in the reservoir are dispersed onto the bearing surface of the worm.

Claims (21)

1. A worm drive system, comprising:

a motor for rotating a worm, the worm having a bearing surface integrally formed at a distal end of the worm, wherein the bearing surface of the worm is rotatably received by a bearing surface integrally formed with a housing of the worm drive system, the housing also surrounding the worm, wherein a lubrication reservoir is located proximate to the bearing of the housing such that a lubrication media located in the reservoir is dispersed onto the bearing surface of the worm as it rotates within the housing; and

a cover secured to the housing, wherein the cover when secured to the housing secures the worm bearing surface in the housing by retaining the worm bearing surface against the bearing surface integrally formed with the housing that houses the worm, and wherein the cover when secured to the housing traps the lubrication media in the reservoir, wherein the worm drive system is located in an actuator of a vehicle latch.

2. The worm drive system as in claim 1 , wherein the worm is operatively coupled to a worm gear pivotally mounted to the housing.

3. The worm drive system as in claim 1 , wherein the motor is a DC motor.

4. The worm drive system as in claim 1 , wherein the worm is operatively coupled to a worm gear pivotally mounted to the housing, wherein rotation of the worm changes the state of an actuator the worm drive system is associated with.

5. The worm drive system as in claim 1 , wherein the worm is operatively coupled to a worm gear pivotally mounted to the housing, wherein rotation of the worm biases the worm gear into an engaged or disengaged position.

6. The worm drive system as in claim 1 , wherein the lubrication reservoir is located below the bearing surface of the worm and wherein the lubrication media trapped in the lubricant reservoir will lubricate the worm bearing surface.

7. A vehicle latch, comprising:

an actuator with a worm drive system, the worm drive system comprising:

a motor for rotating a worm, the worm having a bearing surface integrally formed at a distal end of the worm, wherein the bearing surface of the worm is rotatably received by a bearing surface integrally formed with a housing of the vehicle latch, the housing also surrounding the worm, wherein a lubrication reservoir is located proximate to the bearing of the housing such that a lubrication media located in the reservoir are dispersed onto the bearing surface of the worm as it rotates within the housing; and

a cover secured to the housing, wherein the cover when secured to the housing secures the worm bearing surface in the housing by retaining the worm bearing surface against the bearing surface integrally formed with the housing that houses the worm, and wherein the cover when secured to the housing traps the lubrication media in the reservoir.

8. The vehicle latch as in claim 7 , wherein the worm is operatively coupled to a worm gear pivotally mounted to the housing.

9. The vehicle latch as in claim 7 , wherein the worm is operatively coupled to a worm gear pivotally mounted to the housing, wherein rotation of the worm changes the state of the actuator.

10. The vehicle latch as in claim 7 , wherein the lubrication reservoir is located below the bearing surface of the worm and wherein the lubrication media trapped in the lubricant reservoir will lubricate the worm bearing surface.

11. A method of lubricating a worm drive system, comprising:

rotatably mounting an integral bearing surface located at a distal end of a worm in a housing of the worm drive system, wherein the integral bearing surface of the worm rotatably engages a bearing surface integrally formed with the housing of the worm drive system, the housing also surrounding the worm; and

lubricating the integral bearing surface of the worm with a lubrication media stored in a reservoir located proximate to the bearing surface of the housing of the worm drive system;

trapping the lubrication media in the reservoir with a cover secured to the housing of the worm drive system, wherein the cover secures the integral bearing surface of the worm to the integral bearing surface of the housing of the worm drive system by retaining the integral bearing surface of the worm against the bearing surface integrally formed with the housing that houses the worm, wherein the worm drive system is located in an actuator of a vehicle latch.

12. The method as in claim 11 , wherein the worm is operatively coupled to a worm gear pivotally mounted to the housing.

13. The method as in claim 11 , wherein the worm is operatively coupled to a worm gear pivotally mounted to the housing, wherein rotation of the worm changes the state of an actuator the worm drive system is associated with.
