Abstract
The present invention relates to a kind of gear positioning structure, it includes table base and axle；Described axle is arranged on table base, and axle taper roll bearing is fixed on table base；Above axle, load the first spacer, push down with gland, external diameter at gland puts an O, prevents oil immersion from entering, and with bolt, gland is fixed on table base, the second spacer it is provided with below taper roll bearing, described gear is mounted on an axle, and loads the 3rd spacer of two halves in the lower section of gear, the groove of axle, with a set, the spacer of two halves is entangled again, prevent from separating about the spacer of two halves, put a jump ring in the lower section of set, prop up set.The present invention compared with prior art, simple in construction, compact and reasonable；Safety coefficient can be increased；With jump ring excesssive gap when avoiding installing, gear weight can be made to act on the damage that can effectively avoid jump ring on spacer.
Description
Technical field
The present invention relates to a kind of location structure, specifically a kind of gear positioning structure, be particularly well-suited to vertical lathe, belong to the adnexa of vertical lathe.
Background technology
Vertical car is mainly used in processing large-scale, the heavy workpiece that diameter is big, length is short and is difficult to the workpiece of clamping on horizontal lathe, in the case of tactical diameter meets, the heaviest workpiece is difficult to clamping at sleeping carriage, due to dead weight, machining accuracy is had an impact, uses vertical car can solve the problems referred to above.
In prior art, during axle right angle setting, gear is fixed, traditional mode for fix with a jump ring in gear lower end or upper end, if install time with jump ring excesssive gap, jump ring can be made to be easily damaged, therefore the location to gear be optimized design just seem particularly necessary.
Summary of the invention
It is an object of the invention to overcome above-mentioned weak point, it is provided that a kind of gear positioning structure, this location structure simple in construction, ingenious, reasonable；It is avoided that the damage of jump ring, adds safety coefficient.
The technical scheme provided according to the present invention: a kind of gear positioning structure, including gland, the first spacer, table base, taper roll bearing, the second spacer, axle, gear, the 3rd spacer, set and jump ring；Described axle is arranged on table base, on the table base that axle taper roll bearing is fixed on；Above axle, load the first spacer, push down with gland, external diameter at gland puts an O, prevents oil immersion from entering, and with bolt, gland is fixed on table base, the second spacer it is provided with below taper roll bearing, described gear is mounted on an axle, and loads the 3rd spacer of two halves in the lower section of gear, the groove of axle, with a set, the spacer of two halves is entangled again, prevent from separating about the spacer of two halves, put a jump ring in the lower section of set, prop up set.
As a further improvement on the present invention, the spacer of described two halves is vertically disposed in the groove of axle.
The present invention compared with prior art, simple in construction, compact and reasonable；Safety coefficient can be increased；With jump ring excesssive gap when avoiding installing, gear weight can be made to act on the damage that can effectively avoid jump ring on spacer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As it is shown in figure 1, gland 1, nut 2, O the 3, first spacer 4, table base 5, taper roll bearing the 6, second spacer 7, axle 8, gear the 9, the 3rd spacer 10, set 11, jump ring 12.
As it is shown in figure 1, one gear positioning structure of the present invention, including table base 5, the axle 8 being arranged on table base 5, on the table base 5 that axle 8 is fixed on taper roll bearing 6；Above axle 8, first put into the first spacer 4, pushing down with gland 1, the external diameter of gland 1 puts an O 3, prevents oil immersion from entering again, it is fixed on table base 5 with 2 glands 1 of bolt, as it can be seen, put second spacer 7 below taper roll bearing 6, below taper roll bearing 6 and between gear 9, it is provided with the second spacer 7, described gear 9 is arranged on axle 8, and such gear 9 direction up is just fixed；Lower section at gear 9, the 3rd spacer 10 of two halves is put in the groove of axle 8, the 3rd spacer 10 being so disposed vertically two halves will the weight of carrier gear 9, entangle with the 3rd spacer 10 of 11 two halves of a set again, the 3rd spacer about 10 preventing two halves separates, a jump ring 12 is put in lower section at set 11 again, somewhat props up set 11.
It is an advantage of the current invention that: with jump ring excesssive gap when avoiding installing, jump ring can be made to be easily damaged, so make gear weight act on the damage that can effectively avoid jump ring on spacer.
