Definitions

  • This invention relates to winches for winding a cable, strap or rope to pull such as watercraft and, in particular, to a winch with a gearing system to change gear ratios for operation which does not require shifting between different gears providing constant meshing of the gears for improved durability.
  • cranks are popular mechanisms for pulling vehicles such as watercraft onto their trailers or other storage facilities.
  • the typical winch incorporates a crank with a crank gear mounted to the crankshaft and in engagement with the drum upon which the line is wrapped. Rotation of the crank and crank gear causes the drum to rotate collecting the line on the drum.
  • the crank effort is dictated by the gear ratio between the crank gear and the drum gear.
  • the consumer must purchase the winch which incorporates the gear ratio required for a particular application.
  • the present invention overcomes the disadvantages of the prior known winches by providing a constant mesh gearing system which allows shifting between gear ratios by longitudinally moving the crankshaft for operation in accordance with performance requirements.
  • the winch of the present invention includes a winch housing to which the components are mounted including a winch drum upon which a winch line is wrapped.
  • the winch drum includes a gear for rotatably driving the drum on a drum shaft mounted to the housing.
  • a crankshaft and a driveshaft are mounted to the housing in parallel alignment with the drum shaft.
  • the winch cranks are attached to the crankshaft for rotation of the crankshaft to rotatably drive one of at least two different crank gears mounted coaxial with the crankshaft.
  • the crankshaft includes a fixed gear tooth which can be shifted between the crank gears to selectively drive a single crank gear Detent means on the crankshaft prevents inadvertent shifting of the crankshaft between crank gears.
  • crank gears are in constant mesh with drive gears forming the different gear ratios.
  • the drive gears are mounted to the drive shaft which also includes a ratchet gear in constant mesh with the winch gear such that rotation of the drive gears rotates the ratchet gear and winch gear.
  • crankshaft Longitudinal shifting of the crankshaft will cause the fixed gear tooth to engage the hub of one of the crank gears depending upon the desired gear ratio. Once engaged with the hub, rotation of the crank will cause the selected crank gear and its meshed drive gear to rotate in accordance with the gear ratio. Rotation of the drive gear in turn rotates the drive shaft, ratchet gear and winch gear for rotation of the winch drum.
  • the crank and drive gears remain in constant mesh with only a specific set of gears being chosen by shifting the crankshaft.
  • a standoff is mounted to the ratchet pawl which holds the ratchet pawl away from the ratchet gear eliminating the well-known ratchet noise of typical winches.
  • a winch 10 embodying the present invention is adapted to rotatably retract a flexible line such as a rope or cable for pulling heavy objects.
  • a flexible line such as a rope or cable
  • the winch 10 is used to pull a watercraft onto its trailer or other storage structure.
  • gear ratios little effort is needed to pull a heavy object.
  • the prior known winches had a fixed gear ratio built into the winch which could not be changed.
  • the present invention allows the gear ratio to be changed for multi-speed operation.
  • the winch 10 of the present invention includes a housing 12 to which the components of the winch 10 are mounted and which facilitates attachment of the winch 10 to a support structure.
  • the housing 12 preferably comprises a metal frame 14 having opposing side walls 16.
  • a winch drum 18 upon which a tow line (not shown) is rotatably wrapped.
  • the winch drum 18 is secured to a drum bearing 20 rotatably mounted to a winch shaft 22 secured at opposite ends to the housing 12.
  • a winch gear 24 mounted to the drum 18 for rotation therewith.
  • crankshaft 28 rotatably mounted to the side walls 16 of the housing 12 to extend through the housing 12.
  • the crankshaft 28 is longitudinally movable to shift between gear ratios in accordance with the present invention.
  • Coaxially mounted on the crankshaft 28 is at least two crank gears 30 corresponding to the gear ratios of the winch 10.
  • the present invention will be described in connection with a first crank gear 32 and a second crank gear 34 selectively drivable by the crankshaft 28.
  • additional crank gears may be employed to provide a wider range of gear ratios.
  • crank gears 32 and 34 include a hub slot 36 and 38 adapted to selectively receive a crank tooth 40 fixedly formed on the crank shaft 28 (Figs. 3A and 3B) in order to rotatably drive the respective crank gear 30 upon rotation of the crankshaft 28.
  • the crankshaft 28 also includes detent means 42 preferably formed in an opposite end of the crankshaft 28.
  • the detent means 42 includes a pair of detents 44 formed on the crankshaft 28 corresponding to the spacing and number of crank gears 30.
  • the detents 44 selectively receive ball bearings 46 biased against the crankshaft 28 by springs 48. The force of the springs 48 can be overcome to move the crankshaft 28 longitudinally but the bearings 46 prevent inadvertent movement of the crankshaft 28 during operation thereby ensuring that the crank tooth 40 will be engaged with the corresponding crank gear 30.
  • a drive shaft 50 Rotatably mounted to the housing 12 parallel to the drum shaft 22 and the crankshaft 28 is a drive shaft 50. Fixedly mounted to the drive shaft 50 for simultaneous rotation are drive gears 52 corresponding to the number of crank gears 30.
  • a first drive gear 54 mounted to the drive shaft 50 is in driving engagement with the first crank gear 32 and a second drive gear 56 is in driving engagement with the second crank gear 34.
  • the size of the drive gears 54 and 56 is dictated by the size of the crank gears 32 and 34 to ensure meshing engagement between the gears. Accordingly, rotational drive is transferred from the crankshaft 28 and crank gears 30 to the drive gears 52 and drive shaft 50.
  • a ratchet gear 58 and a ratchet wheel 60 are also mounted to the drive shaft 50 for rotation therewith.
  • the ratchet gear 58 drivingly engages the drum gear 24 to transfer rotation to the drum 18.
  • the ratchet wheel 60 is engaged by a ratchet pawl 62 to prevent unwinding of the winch 10 until desired.
  • the pawl 62 is pivotably mounted to a bracket 64 to repeatedly engage the teeth of the ratchet wheel 50 facilitating rotation in a first direction but preventing rotation in the opposite direction.
  • a standoff 66 Associated with the ratchet pawl 62 which allows "noiseless" operation of the winch 10. In the conventional winch 10, the chatter or clicking of the pawl is widely recognized.
  • the standoff 66 holds the pawl 62 away from the ratchet wheel 60.
  • the standoff 66 engages a circular outer surface 68 of the ratchet wheel 60 to pivot the pawl 62 outwardly away from the ratchet wheel 60.
  • Operation of the present invention allows selection between different gear ratios of the winch 10 by simply shifting the crankshaft 28.
  • the user can shift the crankshaft between the low gear ratio associated with crank gear 32 and the high gear ratio associated with crank gear 34.
  • the crank tooth 40 is engaged with the hub 36 of the first crank gear 32.
  • the crankshaft 28 is moved longitudinally overcoming the detent means 42 to engage the crank tooth 40 with the hub 38 of the second crank gear 34.
  • crank gear 30 engaged, rotation of the crank 26 will transfer rotation from the crank gears 30 to the drive gears 52 which transfers rotation to the ratchet gear 58 and drum gear 24 to wind the line onto the drum 18.
  • the standoff 66 maintains the pawl 62 away from the ratchet wheel 60.
  • the standoff pivots outwardly allowing the pawl 62 to engage ratchet wheel 60 preventing further rotation of the winch drum 18.
