Abstract
The utility model relates to a key groove machining tooling for a herringbone gear. The tooling comprises a base, a supporting sliding block, a thimble, a tightening screw and a guide key, wherein a boss of a positioning gear is arranged on the base, a guide groove which points at a central axis of the base is arranged on the upper surface of the base on one side of the boss, the supporting sliding block is arranged above the guide groove, the supporting sliding block is fixedly connected with the guide key inside the guide groove, the supporting sliding block is fixedly connected with the guide key through the base by a bolt, the thimble and the tightening screw which point at the central axis of the base are arranged on the supporting sliding block, and the thimble is screwed and driven by the tightening screw. By the aid of the tooling, the centering precision of the combined herringbone gear is improved, so that the combined herringbone gear is stable to operate and small in axial load during usage, service lives of the gear and a shafting bearing are prolonged, and the cost is greatly saved.
Description
Technical field
The utility model relates to a kind of keyway processing tool of herringbone bear, is particularly useful for having the processing of the high combination double helical tooth that tooth is required.
Background technology
The advantages such as herringbone bear is high owing to its bearing capacity, and stable drive and axial load are little, therefore making up herringbone bear is subject to extensive use, usually can be widely used in the transmission system of heavy-duty machinery.In most cases, herringbone bear is designed to the centre leaves a certain amount of escape, but this double helical tooth alignment degree mainly is to guarantee by line, final alignment degree error (is generally 0.4～0.5mm) greatly.Some occasion is designed to herringbone bear without the escape form, and the herringbone bear machine tool of this structure can't be finished, and difficulty of processing is large, cost is high; And existing combination herringbone bear generally can be designed to two helical gears that rotation direction is opposite, is assembled into herringbone bear after machining, yet the design of this combination herringbone bear has also brought the centering difficulty of herringbone bear.
The utility model content
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, a kind of keyway processing tool of herringbone bear is proposed, this frock is in the situation that guarantee frock self precision, the alignment degree error of cutting out behind the keyway assembling herringbone bear can reach 0.03～0.05mm, thereby obtains higher precision with less cost.
In order to solve above technical problem, the utility model provides a kind of keyway processing tool of herringbone bear, mainly comprise base, support slipper, thimble, hold out against screw and feather key, the boss that has Positioning Gear on the described base, base upper surface in described boss one side has the guide groove that bar points to the base central axis, described top of guide slot is provided with support slipper, and the described support slipper feather key interior with being located at described guide groove is fixedly connected with; Described base is connected and fixed described support slipper and feather key through bolt again; Be provided with the thimble that points to the base central axis and hold out against screw at described support slipper, described thimble is subjected to the described screw that holds out against to screw driving.
The technical scheme that the utility model further limits is: the keyway processing tool of aforesaid herringbone bear, and the described base boss outside also is provided with the lining that cooperates with bore to be processed; By resleeve more can process different in the gear keyway of hole dimensions, more resleeve can also be used to the damage of protecting base to cause because of being dismounted for multiple times simultaneously; This lining outer ring and key groove gear endoporus to be cut are by little matched in clearance, and inner ring and base are guaranteed easy disassembling and not fragile by too small matched in clearance.
The keyway processing tool of aforesaid herringbone bear, described base boss vertical plane and base horizontal plane intersection leave grinding wheel groove, so that skiving processing.
Further, the keyway processing tool of aforesaid herringbone bear, the described screw that holds out against adopts fine thread.
The beneficial effects of the utility model are: the utility model has improved the accuracy of alignment of combination herringbone bear, more steadily axial load is less so that the combination herringbone bear in use turns round, and also improved gear and axle is the service life of bearing from it seems for a long time, thereby saved greatly cost.

The specific embodiment
Embodiment 1
The keyway processing tool of a kind of herringbone bear that the present embodiment provides, structure as shown in Figure 1, mainly comprise base 1, support slipper 6, thimble 7, hold out against screw 8 and feather key 3, the boss that has Positioning Gear on the base 1, base upper surface in boss one side has the guide groove that bar points to the base central axis, top of guide slot is provided with support slipper, and the support slipper feather key interior with being located at guide groove is fixedly connected with by soket head cap screw 4; Base is connected and fixed support slipper and feather key through hex bolts 5 again; Be provided with the thimble that points to the base central axis and hold out against screw at support slipper, thimble is held out against screw and is screwed driving, and holds out against screw employing fine thread.
Base 1 boss in this enforcement outside also is provided with the lining 2 that cooperates with bore to be processed, by resleeve more can process different in the gear keyway of hole dimensions, the while more resleeve can also be used to the damage of protecting base to cause because of being dismounted for multiple times; This lining outer ring and key groove gear endoporus to be cut are by little matched in clearance, and inner ring and base are guaranteed easy disassembling and not fragile by too small matched in clearance, leave grinding wheel groove at base boss vertical plane and base horizontal plane intersection.
The present embodiment operating procedure: make as requested tooth frock one cover first, guarantee the precision of frock self.When treating Gear Processing to the line cutting action, with of the present utility model the tooth frock is processed in pairs, namely a left-handed gear and a dextrorotation gear are a pair of combination herringbone bear, and coupling gear need make marks; Locate at the gear basic face, by feather key base is connected with support slipper, and can in guide key groove, slide, guarantee that this fractional error is at 0.01～0.02mm, head into key groove gear teeth groove to be cut by thimble, error is controlled in the 0.01mm between thimble and the support slipper, and guarantees that coupling gear thimble institute heights of roofs is consistent; By endoporus and thimble positioning cutting keyway, change coupling gear after having cut at last keyway.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
