Abstract
The utility model discloses a kind of lathe transmission system overload protection arrangements; including female splined shaft; the splined shaft of female splined shaft connection geared head output; obtain driving force; female splined shaft is mounted in internal spline seat, and internal spline seat is driven by female splined shaft and rotated, and internal spline seat passes through load pin connection connecting plate; internal spline seat is socketed with outer gear sleeve, and outer gear sleeve can be rotated with internal spline seat.The beneficial effects of the utility model are to carry out lathe overload protection using new device, lathe can be allowed to continue to come into operation faster, improve efficiency, reduce the expense for replacing bakelite gear.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is related to a kind of lathe transmission system overload protection arrangement.
Background technology
When in use, due to operating unskilled and equipment is unfamiliar with, operation error happens occasionally lathe, and equipment is made
Into certain damage, maintenance rate is high, and producer is during design of lathe, to prevent operation error from damaging lathe, is driven in lathe
Bakelite gear, effect of the bakelite gear in lathe are mounted in system, bakelite gear transmits torque between two gears, when
During more than certain load, just take the lead in damage bakelite gear, equipment fault transmission is caused to stop, so as to protect gear-box.Although
Bakelite gear is readily replaceable, but the service life of bakelite gear is low, yielding abrasion, compared to its ability to bear of metal gear
Very low, under shock loading or heavy duty, the flank of tooth is also easy to produce local plastic deformation and fracture, influences the use of lathe.
Utility model content
The purpose of this utility model is to provide a kind of lathe transmission system overload protection arrangements, solve at present using glue
Mortice wheel carry out lathe overload protection, but but bakelite gear service life it is low, yielding abrasion, replacement cost is high to ask
Topic.
Technical solution is to include female splined shaft used by the utility model, the spline of female splined shaft connection geared head output
Axis obtains driving force, and female splined shaft is mounted in internal spline seat, and internal spline seat is driven by female splined shaft and rotated, and internal spline seat is led to
Load pin connection connecting plate is crossed, internal spline seat is socketed with outer gear sleeve, and outer gear sleeve can be rotated with internal spline seat.
Further, connecting plate connects next stage gear with attachment screw by baffle ring.
The beneficial effects of the utility model be using new device carry out lathe overload protection, can allow faster lathe after
It is continuous to come into operation, efficiency is improved, reduces the expense for replacing bakelite gear.
Description of the drawings
Fig. 1 is a kind of lathe transmission system overload protection arrangement structure diagram.
In figure, 1. female splined shafts, 2. internal spline seats, 3. load pins, 4. connecting plates, 5. outer gear sleeves, 6. baffle rings,
7. attachment screw.
Specific embodiment
The utility model is described in detail With reference to embodiment.
The utility model includes female splined shaft 1 as shown in Figure 1, and female splined shaft 1 connects the splined shaft of geared head output, obtains
Driving force, female splined shaft 1 are mounted in internal spline seat 2, and internal spline seat 2 drives rotation by female splined shaft 1, and internal spline seat 2 passes through
Load pin 3 connects connecting plate 4, and internal spline seat 2 is socketed with outer gear sleeve 5, and outer gear sleeve 5 can be rotated with internal spline seat 2.
Connecting plate 4 connects next stage gear by baffle ring 6 and attachment screw 7.
The power of geared head output imparts power to outer gear sleeve 5 through load pin 3, is engaged by gear then by power
Next stage gear is passed to feed change unit, when being more than 3 bearing capacity of load pin such as loading force, the point of load of load pin 3 is in the work of power
Its power is made to disappear with lower can fracture moment, to ensure personal safety and equipment safety.
It is also an advantage of the present invention that a clutch is set to carry out in the spindle box of lathe equipments and change gear box junction
Protection is carried, operator's maloperation is made motion of main shaft and lathe tool to be allowed to move and disengage after touching knife, so as to ensure the safety of lathe, is helped
In us in lathe student teaching practising method operating process, ensure machine safety and improve the effect of working efficiency.
The above is only the better embodiment to the utility model, not makees any form to the utility model
On limitation, every according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations
With modification, belong in the range of technical solutions of the utility model.
