Abstract
The utility model relates to a driving unloading mechanism of a tapping power head, wherein a main shaft (1) is fixedly connected with a guide threaded sleeve (4); a master form screw thread (2) is formed in the guide threaded sleeve (4); the periphery of the guide threaded sleeve (4) is provided with a guide nut (3); the middle section of the main shaft (1) is a spline (9); the periphery of the spline is provided with a spline sleeve (5); the periphery of the spline sleeve (5) and a belt pulley (6) are combined into a whole body; an unloading deep groove bearing (7) and a thrust bearing (8) are arranged between the belt pulley (6) and the spline sleeve (5); the deep groove bearing (7) and the thrust bearing (8) are arranged on a bracket (11); the main shaft (1) is arranged in a tapping power head body (10) below the main shaft (1); a spline sliding combination is between the spline sleeve (5) and the main shaft (1) in the axial direction; and the guide nut (3) and the guide threaded sleeve (4) form a screw thread rotation combination. The driving unloading mechanism can reduce the axial internal clearance and the radial force of the main shaft, reduce noises, and improve the machine reliability.
Description
Technical field
The invention relates to unloading mechanism, is specifically related to a kind of tapper unit transmission unloading mechanism.
Background technology
When present transmission drives the tapper unit rotation by belt wheel, the load that belt wheel bore has directly been passed to main shaft, is easy to generate the end-play (axial pre tightening force) and the radial load of main shaft like this, causes parts to lose efficacy easily, produce noise, reduce the reliability of machine.
Summary of the invention
The technical problem that the invention will solve provides and a kind ofly can reduce main shaft end-play and radial load, minimizing noise, improves the tapper unit transmission unloading mechanism of machine reliability.
For achieving the above object, the technical scheme of the invention is: a kind of tapper unit transmission unloading mechanism, it is characterized in that tapper unit transmission unloading mechanism comprises main shaft 1, guiding nut 3, guide screw cover 4, spline housing 5, belt pulley 6, zanjon bearing 7, thrust bearing 8, tapper unit body 10 and support (11); Main shaft 1 overlaps 4 with guide screw fixedlys connected, and is pattern screw thread 2 in the guide screw cover 4, and guide screw is overlapped 4 peripheries guiding nut 3 is housed; The stage casing of main shaft 1 is a spline 9, and its periphery is equipped with spline housing 5, and the periphery of spline housing 5 and belt pulley 6 are combined into one, and the zanjon bearing 7 and the thrust bearing 8 of off-load is housed between belt pulley 6 and the spline housing 5; Zanjon bearing 7 and thrust bearing 8 are loaded on the support (11); Main shaft 1 is contained in the tapper unit body 10 of below; Axially make up for spline slides between spline housing 5 and the main shaft 1, guiding nut 3 and guide screw cover 4 are the screw thread rotation combination.
When power drove belt pulley 6 rotations, main shaft 1 and spline housing 5 axially rotated with belt pulley 6, and guide screw cover 4 is also along with rotation, owing to be the screw thread rotation combination between guide screw cover 4 and the guiding nut 3, because of the effect of spiral, when guiding nut 3 fixedly the time, guide screw cover 4 just moves up and down together with main shaft 1; Because spline housing 5 and main shaft 1 make up for spline slides, so 6 of belt pulleys will rotatablely move and pass to main shaft 1, and zanjon bearing 7 and thrust bearing 8 be housed between belt pulley 6 and the spline housing 5, the load that they act on the belt pulley 6 just has been given to support 11 by these two bearings, so just can play the effect that end-play strengthens and radial load increases of stopping, having solved tapper unit lost efficacy owing to parts that belt wheel end-play increase and radial load cause in the high strength running, can reduce noise, improve the reliability of machine.
