Description
Technical field
The utility model is related to machinery manufacturing technology field, and in particular to a kind of enclosed type shaft end limiting locking device.
Background technology
Bearing pin can static state be fixedly connected, can also be done relative motion with connected piece, be mainly used in two part hinged places, constitute
Chain connection.When axle and connected piece need to limit relative motion, two schemes are generally used at present, one kind is that shaft end milling one is flat
Face, by baffle plate and the plane contact for being fixed on connected piece, is relatively fixed by baffle plate and axial plane and limits turning for axle
Dynamic, baffle plate bores unthreaded hole at two, is bolted on connected piece.In the case where axle relative rotation torque is larger, bolt
Easily broken disconnected and limiting locking is failed.Another kind is draw-in groove, open closure one end at each milling one of axle both sides symmetric position
Directly contacted with axle draw-in groove, the rotation of axle is limited by the draw-in groove plane contact on baffle plate and axle, a unthreaded hole is bored on baffle plate, passed through
It is bolted on connected piece.In the case where axle relative rotation torque is larger, open closure stress causes shedding deformation
Limiting locking device fails.
The content of the invention
For drawbacks described above, the purpose of this utility model is to provide a kind of enclosed type shaft end limiting locking device, structure letter
It is single, it is easy to use, axle end baffle plate reaction torque intensity is improve, it is particularly well-suited to structure constraint, axle and connected piece and rotates against
The larger occasion of moment of torsion.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of enclosed type shaft end shrinking device, including
Connected piece, fluting bearing pin, fixing bolt, enclosed type axle end baffle plate etc..The connected piece is not ad hoc structure, above there is bearing pin
Coordinate the screwed hole of perforate and fixed axle end baffle plate；The fluting end part of pin shaft is machined with and coordinates draw-in groove with closed guard；It is described
Fixing bolt is universal standard part；Enclosed type axle end baffle plate one end perforate is fixed on connected piece by the fixing bolt
On, other end perforate groove milling coordinates with the fluting bearing pin draw-in groove, reaches the purpose of shaft end limiting locking.
The utility model when in use, appropriate size fixing bolt and fluting is selected according to the connected piece use condition
Bearing pin, the fluting bearing pin is penetrated in the connected piece corresponding aperture, and the enclosed type axle end baffle plate semicircle orifice passes through slotted pin
The cylindrical rear intermediate rectangular groove of axle coordinates with bearing pin both sides straight trough realizes the slotted pin Axial and radial locking, and the fixing bolt passes through
Spring washer is fixed in the connected piece screwed hole through the enclosed type axle end baffle plate unthreaded hole, realizes the axle of the fluting bearing pin
To spacing.
The beneficial effects of the utility model are：The connected piece is not ad hoc structure, only coordinates with bearing pin thereon and connects
Connect and processed near hole a screwed hole, processing is simple and influences smaller to connected piece；The bearing pin is using former non-bearing position two
Side notching construction, bearing pin use intensity and internal lubrication hole are not influenceed, can meet operating mode use requirements different with connected piece；Institute
Stating fixing bolt can as needed increase spring washer using standard component, and it is convenient to dismount, and easily safeguard；The enclosed type axle end baffle plate with
Existing baffle plate is compared, and enhancing radial direction coupling mechanism force, and can be further added by unthreaded hole in blind end as needed further improves shaft end limit
Capability.
Compared with prior art, the utility model optimizes axle end baffle plate structure, improves dam forces condition, is not changing
While becoming original fluting bearing pin and connected piece, it is possible to achieve fast assembling-disassembling, and improve the limiting locking energy of axle end baffle plate
Power.
