Abstract
The utility model discloses a clearance adjustment device for spiral bevel gears of a universal milling head and belongs to the technical field of manufacture of equipment for mechanical processing. The clearance adjustment device comprises a first spiral bevel gear and a second spiral bevel gear connected with the first spiral bevel gear, wherein the first spiral bevel gear is connected with a supporting bearing and an adjusting pad. The clearance adjustment device also comprises an adjusting screw and a flat point set screw, wherein the adjusting screw is used for adjusting the clearance between the first spiral bevel gear and the second spiral bevel gear. The first spiral bevel gear, the supporting bearing and the adjusting pad are arranged in the inner cavity of an adjusting shaft sleeve, and the adjusting shaft sleeve is connected with a milling head swivel mount in a matched manner. The clearance adjustment device can solve the problems that when the gear clearance of the spiral bevel gears is adjusted with the traditional mode, the assembly efficiency is low, the workload is large, and the assembly quality cannot be ensured.
Description
Technical field
The utility model relates to the equipment manufacturing technology field of machining, especially a kind of universal milling head spiral bevel gear lash adjusting device for the adjustment of universal milling head spiral bevel gear lash adjusting device gear clearance and gear position adjustment.
Background technique
At present, what the gear clearance adjustment of universal milling head internal helicoid umbrella gear adopted mostly is that traditional adjustment mode is adjusted, and that utilizes spacer adjustment exactly, adjusts gear clearance by this technological scheme, has the following disadvantages:
1, need frequent mounting or dismounting spiral bevel gear and other correlated parts relevant with it, and be difficult for measuring, so efficiency of assembling is very low.
2, after spiral bevel gear foot wheel abrasion, change spacer, just need to dismantle spiral bevel gear and other correlated parts, workload is large, and assembly quality can not guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of universal milling head spiral bevel gear lash adjusting device, and it can solve while adjusting the gear clearance of spiral bevel gear with traditional approach, and efficiency of assembling is low, and workload is large, the unwarrantable problem of assembly quality.
In order to address the above problem, the technical solution adopted in the utility model is: this universal milling head spiral bevel gear lash adjusting device, comprise the first spiral bevel gear, the second spiral bevel gear being connected with described the first spiral bevel gear, described the first spiral bevel gear is connected with block bearing and spacer, also comprises adjustment screw and flush end Cock screw for adjusting the gap between described the first spiral bevel gear and described the second spiral bevel gear; Described the first spiral bevel gear, block bearing and spacer are arranged on adjustment bore sleeve, and described adjustment axle sleeve and milling head swivel base are connected.
In technique scheme, more specifically scheme can also be: described adjustment axle sleeve is interference fit with coordinating of described milling head swivel base.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect having is the utility model:
1, effectively reduce spiral bevel gear gap required dismounting number of times and can reduce in a large number the repair amount of spacer by threaded adjusting while adjusting, reduce assembling work intensity, improve efficiency of assembling.
2, form bidirectional helical by lock screw and flush end Cock screw and regulate, the repetition dismounting while effectively avoiding adjusting spiral bevel gear gap, the destruction of the precision of reason to precision partss such as bearings such as knocks, and improves assembly quality.
3, the friction between the axially loaded of lock screw and adjustment axle sleeve and milling head swivel base can effectively be offset spiral bevel gear existing axial force in the course of the work, makes umbrella gear have good transmission stability.
4, along with the use break-in of spiral bevel gear, gear clearance will become greatly, now only needs to adjust lock screw and can recover good original precision, facilitates simple and easy.
5, under high temperature rugged environment, because the temperature difference is larger, cause the axial deformation of spiral bevel gear wheel shaft excessive, spiral bevel gear gap is too small, now can pass through to adjust flush end Cock screw, convenient and swift.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail: the universal milling head spiral bevel gear lash adjusting device shown in Fig. 1 and Fig. 2, the first spiral bevel gear 1 is connected with the second spiral bevel gear 7, the first spiral bevel gear 1 is connected with block bearing 4 and spacer 6, also comprises adjustment screw 3 and flush end Cock screw 8 for adjusting the gap between the first spiral bevel gear 1 and the second spiral bevel gear 7; The first spiral bevel gear 1, block bearing 4 and spacer 6 are arranged on adjusts axle sleeve 2 inner chambers, adjusts axle sleeve 2 and is connected with milling head swivel base 5; Adjusting axle sleeve 2 is precision interference-fit with coordinating of milling head swivel base 5.
First bearing 4 is assembled into one with adjusting axle sleeve 2, then this one is put into milling head swivel base 5, then the first spiral bevel gear 1 and spacer 6 are put into and adjusted in axle sleeve 2 from the right, finely tune the extrusion of the first spiral bevel gear 1 left end by spacer 6.By adjusting lock screw 3 and the flush end Cock screw 8 on axle sleeve 2 left sides, get final product the gap of two-way adjustment the first spiral bevel gear 1 and the second spiral bevel gear 7 simultaneously.
