Abstract
The invention discloses a kind of axial direction positioning device of wet clutch, comprise the clutch supporting base offering axle center hole, the upper end of described clutch supporting base is connected with the positioning end cover that center has stud, the radial width of positioning end cover is greater than by the center bore of the clutch of locating, positioning end cover is spun by the axle center hole of described stud and clutch supporting base, it offers central through bore to communicate with the axle center hole of clutch supporting base, positioning end cover is offering oil circuit hole near stud position.This positioning device can reduce the axially locating error of clutch, and structure is simple, easy processing.
Description
Technical field
The present invention relates to a kind of axial direction positioning device of wet clutch.
Background technique
The axial direction positioning device (see Fig. 4, Fig. 5) of existing wet clutch, comprise the clutch supporting base 1 and annular opening collar 8 that offer axle center hole 11, clutch supporting base 1 upper end outer wall offers annular slot, annular opening collar 8 is installed in this annular slot, annular opening collar 8 by with clutch supporting base 1 coordinate the axial position limiting clutch 9.There is the problem of following two aspects in this positioning device: the first, when clutch works, in this device, annular opening collar 8 local pressure is larger, when annular opening collar 8 insufficient rigidity, the single load bearing region of its rim openings side can produce distortion, and the radial dimension of annular opening collar 8 is much smaller than clutch radial dimension, the micro-deformation of annular opening collar size will be exaggerated, and cause clutch to locate misalignment; The second, the wall thickness due to clutch supporting base 1 is less, offering of annular slot, and the rigidity of clutch supporting base 1 at annular slot place and fatigue strength are reduced, and needs the size increasing clutch supporting base 1 region of interest to improve this situation when designing.
Summary of the invention
The object of this invention is to provide the axial direction positioning device of the simple wet clutch of a kind of structure, to reduce the axially locating error of clutch.
The axial direction positioning device of wet clutch of the present invention, comprise the clutch supporting base offering axle center hole, the upper end of described clutch supporting base is connected with the positioning end cover that center has stud, the radial width of positioning end cover is greater than by the center bore of the clutch of locating, positioning end cover is spun by the axle center hole of described stud and clutch supporting base, it offers central through bore to communicate with the axle center hole of clutch supporting base, positioning end cover is offering oil circuit hole near stud position.
Be threaded and can ensure positioning end cover uniform force, also can realize the fine setting of axially locating position simultaneously, oil circuit hole forms oil passage, and lubricant oil is used for lubricating the bearing between clutch supporting base and clutch.
Further, in order to reduce the wearing and tearing of positioning end cover and clutch surface of contact and clutch cover plate surface of contact, the interior edge face of described positioning end cover is provided with first to resistance to wear packing ring, exterior edge face is provided with second to resistance to wear packing ring, described oil circuit hole is positioned at first packing ring and second that resistance to wears and resistance to wears within packing ring.
The shape of positioning end cover can adopt the non-circular structure being convenient to installation, uniform force, the radial width of positioning end cover with can be controlled within 1.75 ~ 2.25 by the diameter ratio of the central through bore of clutch of locating, when the material using rigidity higher, this ratio can suitably improve.
When positioning clutch, be contained in by clutch sleeve on clutch supporting base, be screwed in the center hole of clutch supporting base upper end by stud by positioning end cover, positioning end cover blocks clutch, and limits the axial position of clutch.
The orientation type that positioning device of the present invention adopts clutch supporting base to be threaded with positioning end cover, makes positioning end cover uniform force, can effectively reduce the axially locating error of clutch, and meanwhile, positioning end cover structure is simple, easy processing.

Embodiment
As Fig. 1, Fig. 2, the axial direction positioning device of the wet clutch shown in Fig. 3, comprise the clutch supporting base 1 offering axle center hole 11, the upper end of clutch supporting base 1 is connected with the positioning end cover 2 that center has stud 5, the end face of positioning end cover 2 is the square structure with four identical journal stirrups, the radial minimum width (i.e. the length of side of square structure) of positioning end cover 2 is greater than by the center bore of the clutch 9 of locating, positioning end cover 2 is spun by the axle center hole 11 of stud 5 with clutch supporting base 1, it offers central through bore 3 to communicate with the axle center hole 11 of clutch supporting base, the interior edge face of positioning end cover 2 welding (or bonding) has first to resistance to wear packing ring 6, the exterior edge face of positioning end cover 2 being welded (or bonding) has second to resistance to wear packing ring 7, positioning end cover 2 is circumferentially offering four oil circuit holes 4 near stud 5 position, four oil circuit holes 4 are all positioned at first packing ring 6 and second that resistance to wears and resistance to wear within packing ring 7, and be arranged symmetrically with the medial axis of positioning end cover 2.
First packing ring 6, second packing ring 7 that resistance to wears that resistance to wears that this axial direction positioning device adopts needs good processing plane degree and certain radial dimension to ensure the positioning precision of clutch, and first packing ring 6, second that resistance to wears resistance to wears packing ring 7 welds (or bonding) during with positioning end cover 2 and needs to keep good coaxality to ensure uniform force.
When positioning clutch 9, be sleeved on by clutch 9 on clutch supporting base 1, positioning end cover 2 is screwed in the upper end of clutch supporting base 1 axle center hole 11 by stud 5, positioning end cover 2 blocks clutch 9, and limits the axial position of clutch 9.
