Description

The gear shaft slotting attachment

Technical field

The utility model belongs to Machining Technology field, particularly a kind of gear shaft slotting attachment.

Background technology

Gear shaft refers to support rotational parts and also turns round therewith to transmit the machine components of motion, moment of torsion or moment of flexure, is generally round metal shaft-like, and each section can have different diameters, and the part of doing gyration in machine just is contained on axle.

Difference nemaline according to axle, axle can be divided into bent axle and d-axis two classes.Carrying situation according to axle can be divided into again: 1. rotating shaft, not only bear moment of flexure but also bear moment of torsion during work, and be modal axle in machinery, as axle in various decelerators etc.; 2. axle is used for supporting that rotational parts only bears moment of flexure and transmitting torque not, and some axle is rotated, and as the axle of rolling stock etc., some axle is not rotated, as the axle of supporting pulley etc.; 3. power transmission shaft, be mainly used to transmitting torque and do not bear moment of flexure, as the long optical axis in crane movable mechanism, driving shaft of automobile etc.

In design, the utilization of gear shaft is several situations once nothing more than generally: 1, gear shaft is generally pinion (gear that the number of teeth is few); 2, gear shaft is generally in high speed level (namely low moment of torsion level); 3, gear shaft seldom as the shifting slide gear of speed change, is generally all generally the gear of fixing operation, the one, because be in level at a high speed, it is that discomfort is carried out the slippage speed change at a high speed; 4, gear shaft is the synthetic integral body of axle and gear, but, when design, still to shorten the length of axle as far as possible, oversize one is to be unfavorable for the upper rolling tooth machined, the 2nd, and the support of axle is oversize to be caused axle to want overstriking and increases mechanical strength (as rigidity, amount of deflection, bending resistance etc.).

In prior art, groove milling operation in the procedure of gear shaft, usually the accurate location that the plain clamp that adopts is difficult to realize part, and each fixture can only clamp a part, machining accuracy and efficient are all lower, and due to the specificity of existing fixture, the product of different size all need design special fixture, and cost drops into higher.
