Abstract
The utility model discloses a kind of pinion gear thermal treatment tooling devices for well annealing furnace, it is made of gear support frame and pedestal two parts, it is uniformly distributed on pedestal and gear support frame to be welded with multiple protrusions, protrusion wherein on pedestal is used for keeping apart gear support frame, protrusion on gear support frame is used for isolation gear, the protrusion of isolation gear is welded on gear support frame, gear support frame end face uses square structure, it is overlapped on cross bar, there is downward eave tile at both ends simultaneously, chassis uses solid steel plate.Gear heat treatment is changed into vertical placement by the present apparatus by the horizontal placement of traditional big end downwards, make gear mutually isolated, significantly improve flank profil surface temperature distribution unevenness and compressive deformation when being heat-treated caused by being contacted due to face of gear with face, solid steel plate chassis adds the stability of structure, gear support frame end face uses square structure, rolling can be generated to avoid gear support frame, while have downward eave tile at both ends, supporting rack is prevented to vertically move.
Description
Technical field
The utility model device is a kind of pinion gear heat treatment for well annealing furnace for belonging to gear heat treatment field
Frock.
Background technology
Gear drive is engaged by driving wheel and driven wheel, transfers movement and power, compared with other transmissions, is had and is passed
It is dynamic than constant, wide adaptation range, reliable operation, last a long time the advantages that, during gear drive, the flank of tooth is subject to pulsating cyclic
The effect of alternation contact stress so that Surface of Gear material generates small fatigue crack, and gradually extends, and forms flank of tooth point
Erosion, causes impact and noise so that transmission failure, the main reason for causing rippling are that the hardness after heat treatment is relatively low, nothing
Method ensures the due contact fatigue strength of gear, and using traditional gear heat treatment frock, gear is placed in stove using stacking,
When being heated to high temperature in stove, lower floor's gear receives upper strata gear gravitational pressure, is easily generated by buckling in heat treatment process
Shape, and stack to place and so that flank profil surface temperature distribution is uneven, it causes tooth surface hardness uneven, easily makes gear failure, by
In a gear failure, be likely to result in the entire production line halt production, seriously affect equipment operation and enterprise's production, make enterprise by
Huge economic losses.
The content of the invention
In view of the above problems, the utility model device, which devises a kind of pinion gear for well annealing furnace, is heat-treated work
Dress, can once be heat-treated multiple pinion gears, and due to being that line contacts between gear and frock, can significantly improve gear
The uneven heating phenomenon in heat treatment process.
The utility model device is mainly by gear support frame, pedestal, cross bar, montant, cross bar protrusion, supporting rack convex sets
Into, it is characterised in that：4 montants are welded on according to the size of furnace inner space on pedestal, after montant is fixed, length are selected to close
Suitable cross bar keeps suitable spacing, is symmetrically welded between two montants, by the raised discrete welding of cross bar above cross bar
On the top, the eave tile direction that supporting rack protrusion is welded on to both ends on the top and gear support frame of gear support frame is opposite.
The utility model device adopts the following technical scheme that：4 montants are uniformly welded on pedestal, as needed at heat
Cross bar is symmetrically welded on montant by the diameter range of reason gear, and the protrusion of isolation supporting rack, Ke Yibao are welded on cross bar
There is a certain distance between card supporting rack, so as to avoid contacting with each other between gear, isolation tooth is welded on gear support frame
The protrusion of wheel avoids mobile in placement gear process middle gear and is in contact the side of adjacent gear and influences heat treatment
Effect, so as to which gear heat treatment is changed into vertical placement by the horizontal placement of traditional big end downwards, significantly improve due to
Face of gear contacted with face caused by heat treatment when flank profil surface temperature distribution it is uneven, gear support frame end face is tied using square
Structure is overlapped on cross bar, can roll to avoid gear support frame vertical cross-bar direction, while have downwards at gear support frame both ends
Hook head structure, supporting rack is prevented to vertically move, gear support frame number can adjust according to the size of gear diameter, improve tooth
The heat treatment efficiency of wheel, chassis use solid steel plate, increase the stability of total, and the gear being heat-treated as needed is straight
Footpath scope determines welding position and its quantity of the cross bar on montant.
The utility model device advantages below and good effect：
1st, the form of gear heat treatment is changed into vertical placement by the device by the horizontal placement of traditional big end downwards,
It is uneven to significantly improve flank profil surface temperature distribution when being heat-treated caused by being contacted due to face of gear with face.
2nd, the device gear support frame both ends use two symmetrical downward eave tiles, can prevent gear support frame from producing
Raw longitudinal movement.
Description of the drawings
The utility model device is further illustrated below in conjunction with the accompanying drawings.

Fig. 2 is one preferred sectional view of this utility unit；
1, pedestal in figure；2nd, cross bar；3rd, cross bar protrusion；4th, montant；5th, gear support frame；6th, supporting rack protrusion.
Specific embodiment
As shown in Figure 1, this frock is mainly used in shaft furnace, which is mainly made of two parts.First
Point；4 montants (4) are welded on according to the size of furnace inner space on pedestal (1), it is adjacent perpendicular according to two after montant (4) is fixed
Distance between tie rods selects corresponding cross bar (2), is symmetrically welded between two montants (4), above cross bar (2) that cross bar is raised (3)
Discrete is welded on top.Second portion：Supporting rack raised (6) is welded on to the top of gear support frame (5).
When using this frock, the link position for the gear size soldering part that should be heat-treated as needed.It is specifically used
When, gear is sequentially sleeved on gear support frame (5), will not be contacted with each other between raised (6) each gear of supporting rack due to having, from
And it avoids uneven in each spot temperature of heat treatment process middle gear.By gear support frame (5) together with gear on cross bar (2)
During putting, the radical of same direction gear support frame (5) should be determined according to the diameter of gear, it is ensured that can be to greatest extent
Using furnace inner space without making have contact between gear.
