Description
Technical field
The present invention is mainly concerned with the transmission device field, the all-hydraulic grader that refers in particular to a kind of Hooks coupling universal coupling and this Hooks coupling universal coupling is installed.
Background technique
In all-hydraulic grader, travel between oil hydraulic motor and the tandem-driving bogie adopt in the external splines mode that is rigidly connected.Because factors such as the stressed excessive and manufacturing of back axle, assembling cause oil hydraulic motor working spindle and tandem-driving bogie input gear shaft generation disalignment in the grader working procedure, finally can cause the motor spindle spline to be worn even suppress disconnected.Keeping under original back axle and the constant situation of tandem-driving bogie structure, head it off can be set about from following two aspects: 1, tandem-driving bogie is strengthened design; 2, at the increase coupling of driving motors and balance box.In first kind of mode, balance box rigidity directly influences the coaxality of motor spindle and tandem-driving bogie input shaft, but gear housing rigidity can not infinitely strengthen, and can not thoroughly solve the disalignment problem so strengthen casing.In the second way, between driving motors and tandem-driving bogie, coupling is installed, can be solved the fault that the disalignment phenomenon is brought.But according to grader actual conditions and back axle structural type, this kind coupling must satisfy following requirement:
1. the driving motors maximum speed is 4500r/min, requires coupling synchronism height, adapts to the high-speed overload operating mode;
2. coupling is installed in the confined space, requires its compact structure, and boundary dimension is little, and overload protection function is arranged, and exempts from regular maintenance;
3. coupling principal and subordinate moved end Placement is by the decision of motor output shaft and tandem-driving bogie input gear shaft structure, so driven end (being connected with tandem-driving bogie) be external splines, active break (being connected) with motor be internal spline;
4. to guarantee at first that from design principle the oil hydraulic motor main spindle multiple spline does not does not wear and tear, so require to be connected no relative movement between coupling drive end and the motor spindle external splines;
5. there are motor frequent starting and clockwise and anticlockwise phenomenon owing in the actual job, so coupling has shock-absorbing and impact resistance;
6. for guaranteeing that oil hydraulic motor is not damaged, require coupling to have overload protection function, can not damage coupling other part in addition after promptly coupling itself damages.
