Abstract
The utility model discloses a kind of servicing unit of gear teeth tips hardness measurement, including servicing unit base (1) that upper surface is a plane, servicing unit base (1) lower surface has above the groove of one and hardometer workbench form fit, servicing unit base (1) and is respectively arranged with fixing end (2) and movable end (3) perpendicular to servicing unit base (1) upper surface normal direction.Fixation problem of the gear of the utility model solution certainly gear especially even number tooth in tooth top hardness measurement, realizes penetrator stabilization in gear teeth tips, obtains reliable tooth top hardness measurement data.
Description
Technical field
The utility model belongs to hardness measurement testing field, and in particular to the survey tool and method of gear teeth tips hardness.
Background technology
Gear is a kind of conventional mechanical organ moved by continuous engagement transmission with power.Due to the carrying energy of gear
Power has close relationship with its case hardness, and hardness is higher, and its bearing capacity is also higher, therefore, during Gear Production,
Hardness is a key parameter.Tooth top hardness detection method originally is only applicable to the hardness determination of odd number gear tooth top, and even number
The gear of tooth is difficult generally by the hand-held auxiliary of operator due to only one of which tooth positioning in lower section when penetrator acts on tooth top
Exempt to shake or offset, so as to tooth top hardness cannot be measured accurately.
The content of the invention
The technical problems to be solved in the utility model is：In order in gear teeth tips hardness measurement, penetrator can be made
Stable acts on gear teeth tips, it is to avoid bring measurement error because gear fixes shakiness, it is desirable to provide a kind of gear teeth tips are hard
The servicing unit of measurement is spent, fixation problem of the gear of gear especially even number tooth in tooth top hardness measurement is solved, realized hard
Degree meter pressure head stabilization obtains reliable tooth top hardness measurement data in gear teeth tips.
The technical solution of the utility model is as follows：
A kind of servicing unit of gear teeth tips hardness measurement, including the servicing unit base that upper surface is a plane, auxiliary
Device pedestal lower surface has above the groove of one and hardometer workbench form fit, servicing unit base and is filled perpendicular to auxiliary
Bottom set seat upper surface normal direction is respectively arranged with fixing end and movable end.By servicing unit base, fixing end and movable end
Gear is clamped from three directions, it is therefore prevented that gear is moved when hardness is measured, influence measurement accuracy.
The movable end includes that hold-down head and the length adjustment perpendicular to servicing unit base upper surface normal direction are fastened
Device.
The fixing end and movable end are connected by support with servicing unit base, and fixing end and movable end can also be independent
Fixation without being connected with servicing unit base, but to ensure clamping stability of the three to gear.
There is the groove matched with gear-profile on the working face of the fixing end, movable end and servicing unit base.For
Further improvement gear contact with fixing end and movable end and servicing unit base, (namely works in contact surface
Face) increase and can improve stability with the groove of gear profile.
When carrying out tooth top hardness measurement using the present apparatus, first by gear testing servicing unit as on hardometer workbench simultaneously
It is fixed, stabilize it and do not shift.Again by gear clamping in the fixing end of gear testing servicing unit, movable end and auxiliary dress
Between bottom set seat working face, gear is positioned by the length adjustment device of gear testing servicing unit.Finally by hardometer pressure
Head acts on gear teeth table top surface, and smoothly applies test force, and measures its hardness number.For odd number gear, gear has
Two teeth are fixed with fixing end and servicing unit base working face contact respectively, for even number gear, additionally increase a tooth
Fixed with movable end working face and contacted.
The utility model device is simple, easy to operation, it is to avoid in gear teeth tips hardness measurement, due to clamping not
Stabilization, the measuring result error for causing can not carry out the situation of accurate measurement so as to solve to gear teeth tips hardness at present.

Specific embodiment
As shown in figure 1, the servicing unit of gear teeth tips hardness measurement by servicing unit base 1, fixing end 2, movable end 3,
Length adjustment fastener 4 is constituted, and servicing unit base 1 is a cylindrical steel-casting, and lower surface is fluted to work with hardometer
Platform 8 is matched, and the pressure head of fixing end 2 and movable end 3 is the steel-casting that one piece of working face (with Gear Contact Surface) is plane, wherein
One end of briquetting is connected with length adjustment fastener, and length adjustment direction and the upper surface normal direction of servicing unit base 1
Vertically.In gear teeth tips hardness measurement, servicing unit base 1 is firmly installed on 8 hardometer workbench, by tooth to be measured
Wheel is placed on servicing unit base 1, and one end is in close contact with fixing end 2, by length adjustment fastener 4, makes movable end 3
Also it is in close contact with gear, it is ensured that after gear does not loosen, test force is applied in gear under test crown by 7 penetrators, and
Gear teeth tips hardness measurement is read on 6 duremeter number devices.
When the number of teeth is odd number, odd number gear gear teeth tips hardness measurement step is as follows：
First, by gear testing servicing unit 1 as on hardometer workbench 8 and fixed, stabilize it and do not shift.
Second, tested odd number gear is chosen, odd number gear is placed on servicing unit base 1, one end and fixation
End 2 is in close contact, and now gear has 2 teeth to be contacted with servicing unit base 1, and 1 tooth is contacted with fixing end 2.
3rd, adjustment length regulation fastener 4 makes movable end 3 be also in close contact with gear, and locking fastener makes tooth
Wheel is firm, does not loosen.
4th, test force is applied in gear under test crown by penetrator 7, and read on duremeter number device 6
Take gear teeth tips hardness measurement.
When the number of teeth is even number, even number gear tooth top hardness measurement step is as follows：
First, gear testing servicing unit 1 is placed on hardometer workbench 8 and fixed, stabilize it and do not shift.
Second, tested even number gear is chosen, even number gear is placed on servicing unit base 1, one end and fixation
End 2 is in close contact, and now gear has 1 tooth to be contacted with servicing unit base 1, and 1 tooth is contacted with fixing end 2.
3rd, adjustment length regulation fastener 4 makes movable end 3 be also in close contact with gear, and locking fastener makes tooth
Wheel is firm, does not loosen.
4th, test force is applied in gear under test crown by penetrator 7, and read on duremeter number device 6
Take gear teeth tips hardness measurement.
