Description
Technical field
The utility model relates to a kind of tooth bending fatigue experimental device.
Background technology
Gear is widely applied to industrial every field as the kinematic train base components.The excellence of gear manufacturing property and serviceable life just all can be caused the operate as normal of plant equipment and be seriously influenced.Along with the continual renovation and the improvement of gear fatigue life checkout equipment and detection method, gear contact and flexible life prediction are more and more accurate, greatly reduce the heavy losses that plant equipment causes owing to gear failure.Monodentate or bidentate loading method are all adopted in tooth bending torture test at present, promptly load tup and directly contact with gear teeth tooth top, by applying pulsed load, realize gear teeth fracture failure.Therefore, tooth bending fatigue test clamper and the design of loading tup have extremely important influence to test efficiency and experimental precision.Very loaded down with trivial details and difficult during the anchor clamps clamping gear of general tooth bending torture test, and position that can't the rapid adjustment gear tooth, test period is increased, test efficiency reduces, load tup simultaneously and be generally rigid body, in loading procedure, can't guarantee that tooth top is stressed evenly, usually causes test findings inaccurate by the distortion of self.
Summary of the invention
The device of the utility model by but a kind of quick-clamping, adjusting gear position being provided and evenly loading solved the problem that exists in the present tooth bending torture test.
The utility model is realized by following technical scheme:
A kind of tooth bending fatigue experimental device, form by support section and loading section, loading section is formed by loading the tup anchor clamps and loading tup, loading tup is connected with the testing equipment loading section by loading the tup anchor clamps, support section comprises carrier base, two rack side plates, the effect bolt, the effect nut, the chucking screw, the chucking pad, pad, position-adjusting handle and locating piece, carrier base contacts installation with the supporting surface of testing equipment, have boss on the carrier base, rack side plate is positioned at the boss both sides, with carrier base by the coupling bolt connection, each coupling bolt position is not on same horizontal line, male splines of effect bolt band, spline can be installed with the bore groove fit, chucking pad one side contacts installation with gear face, side contacts is installed in opposite side and the rack side plate, pad is installed with the outer side contacts of rack side plate near effect nut one side, the effect bolt passes rack side plate, the chucking pad, bore, pad, be connected with the effect bolt thread, the chucking screw contacts with pad after being screwed into the effect nut, locating piece cooperates with rack side plate top plane contact, loads tup anchor clamps and the vertical center line dead in line of the vertical central axis that loads tup with gear teeth tips that contacts with locating piece and device support face.
Load tup and be projected as rectangular configuration downwards from the clamping end, become the sword type with the tooth top contact jaw, the middle part is an I shape for two sections.
The utility model joint is simple in structure, convenient mounting and clamping, gear position is easy to adjust and load evenly, can shorten the test period, improves test efficiency and quality.

Embodiment
As shown in Figure 1-Figure 3, the utility model is made up of support section and loading section, and support section comprises carrier base 1, rack side plate 2, effect bolt 3, effect nut 4, chucking screw 5, chucking pad 6, pad 7, position-adjusting handle 8, locating piece 11; Loading section comprises loading tup anchor clamps 9 and loads tup 10.
During use, carrier base 1 is contacted installation with the supporting surface of testing equipment, rack side plate 2 and carrier base 1 are by the bolt connection, each coupling bolt position is not on same horizontal line, regulate each coupling bolt, guarantee the entire bracket non-loosening, to test gear 12 both sides and chucking pad 6 contact matching, and be placed between the rack side plate 2, chucking pad 6 and rack side plate 2 inboard contact matching, to act on bolt 3 and rack side plate 2 then, chucking pad 6, test gear 12 endoporus contact matching are installed, and guarantee to act on bolt 3 male spliness and gear 12 endoporus groove fit, pad 7 is placed on place, effect nut 3 one end fixed positions, and assurance pad 7 one sides and rack side plate 2 outer side contacts installations, with the internal and external threads of effect bolt 3 chucking screw 5 is contacted by effect nut 4 with pad 7, the position-adjusting handle of fixing by rotation and effect bolt 38 is adjusted the position of gears 12 at this moment, make the test gear teeth 12 a certain tooth tops and locating piece 11 contact matching, locating piece 11 cooperates with rack side plate 2 top plane contact, tighten chucking screw 5 then, make chucking screw 5 and pad 7 contact matching, increase the clamping force of 2 pairs of gears 12 of rack side plate, gear 12 when loading, tup is not rotated, the installation of fixture support part.The anchor clamps loading section is connected with the testing equipment loading section by loading tup anchor clamps 9, loading tup 10 is fixed together with the experimental facilities loading section, guarantees to load tup anchor clamps 9 simultaneously and load the vertical central axis of tup 10 and the vertical center line dead in line of gear stand under load tooth top and device support face.Load tup 10 and be projected as rectangular configuration downwards from the clamping end, become the sword type with the tooth top contact jaw, the middle part is an I shape for two sections, form yielding zone, during load deflection, the deformed region distortion is cancelled out each other, can regulate the load distribution of tooth top voluntarily, guarantee to load homogeneity.
The utility model loads tup self also can design yielding zone, many places, in experimentation, because the loading tup that clamping sum of errors Errors in Gear Processing etc. causes contacts uneven with tooth top, tup can be regulated the contact area of tup and tooth top according to magnitude of load, realizes evenly loading.Record experimentation and experimental result are carried out interpretation of result.
