Abstract
Disclosed is a general test clamp for the gear bending fatigue; a high-frequency connecting column is arranged on a connecting transverse shaft which is matched with a high-frequency pressure plate through a gap; a gear pressed block is arranged on the high-frequency pressure plate through a pressed block bolt; the transverse shaft and the high-frequency pressure plate are fixed through a pressed block clamping bolt; a cushion block is connected with a T-shaped channel steel through a channel iron fixing bolt; a T-shaped channel iron is connected with a gear support plate through a connecting bolt; a V-shaped groove is arranged on the upper end of the gear support plate; a gear support column is matched with the gear support plate for installation; a loading device is connected with the loading part of the test device; a gear fixing support device is contacted with the support surface of the test device for installation. In the general test clamp, because the connecting transverse shaft is matched with the high-frequency pressure plate through a gap, the loading span of the clamp can be adjusted continuously within a certain range; thereby, the design and manufacturing cycle of the test clamp for the gear bending fatigue is greatly shortened; the clamp cost is reduced and the test efficiency is improved.
Description
Technical field
The utility model belongs to auto parts and components gear test fixture technical field, the tired general test fixture of particularly a kind of tooth bending.
Background technology
The bending fatigue performance of gear is an important performance indexes of gear, and in gear exploitation and gear quality checkout procedure, the repeated bend test of gear also is the work that must carry out.
Span when general tooth bending fatigue test clamper bidentate loads is fixed, and strides the number of teeth when changing for the gear of different spans or same gear, must the different test fixture of design, thus cause the experimentation cost height, length consuming time, efficient is low.
Loading contact region skin hardness and wearing quality in view of the tooth bending fatigue test clamper has specific (special) requirements simultaneously, and neoteric gear test fixture carries out specialized designs to this part aspect structure and the thermal treatment.
Summary of the invention
The purpose of this utility model is the shortcoming at the said gear test fixture, provides a kind of tooth bending tired general test fixture.
The technical solution of the utility model is achieved in that
The tired general test fixture of tooth bending, it is characterized in that: it is made up of charger and gear fixed support device, charger is by the high frequency joint pin, connect transverse axis, the high frequency pressing plate, the gear briquetting, briquetting bolt and briquetting fishbolt are formed, the high frequency joint pin is installed in and connects on the transverse axis, connecting transverse axis and high frequency platen gap cooperates, the gear briquetting is installed on the high frequency pressing plate by the briquetting bolt, connecting transverse axis and high frequency pressing plate is fixed by the briquetting fishbolt, the gear fixed support device is by the gear back up pad, T type channel-section steel, cushion block, coupling bolt, channel-section steel set bolt and gear support column are formed, cushion block and T type channel-section steel are by the connection of channel-section steel set bolt, T type channel-section steel and gear back up pad are by the coupling bolt connection, gear back up pad upper end has the V-type groove, the gear support column cooperates installation with the gear back up pad, the loading section of charger and testing equipment passes through double-screw bolt, be threaded, the gear fixed support device contacts with the supporting surface of testing equipment, and is connected and fixed by bolt; The vertical central axis of the loading section of testing equipment overlaps with the vertical central axis of the supporting surface of equipment, and the charger of anchor clamps and gear fixed support device also are vertical rotation center symmetries,
After the utility model anchor clamps normal mounting, just can guarantee correct position relation, it is parallel with the gear supporting surface and the center is symmetrical promptly to test the power loading surface, thereby make gear can not bear bending stress outside the unwanted loading acting surface, the acting force that warranty test equipment shows is converted into the pressure that gear bears fully.Because connecting transverse axis and high frequency pressing plate is clearance fit, thereby the loading span of anchor clamps is adjustable continuously within the specific limits, thereby has shortened the design and the manufacturing cycle of tooth bending fatigue test clamper greatly, has reduced the anchor clamps cost, has improved test efficiency.
