Abstract
The utility model relates to a large aperture oil-hole cover device which comprises a hole cover base and a hole cover, the hole cover is assembled on the hole cover base through a set of elastic rotary fastening mechanism which is arranged at a port position on the hole cover and the hole cover base. The elastic rotary fastening mechanism consists of a handle shaft which is axially sliding arranged on the hole cover, a reset spring which is covered on the handle shaft outside the hole cover, a spacing bolt which is radially fixed on the handle shaft in the hole cover, and two equal-length, symmetric spacing bars which are fixed on the inner wall of the port position of the hole cover base and matching the spacing bolt, a spacing groove is arranged under each spacing bar. As the utility model changes a screw fastening to the elastic rotary fastening mechanism, once the hole cover is rotated to a proper position, the hole cover is fastened and locked, thereby removing a loosing phenomenon caused by vibration, playing a good effect of oil leakage prevention, reducing oil consumption of gear box, improving reliability of locomotive running, having certain social significance and economic benefit.
Description
Technical field
The utility model relates to a kind of oil-hole cover device, relates in particular to a kind of installing locomotive gear cases large aperture oil-hole cover device.
Background technology
Installing locomotive gear cases is the critical component on all kinds of locomotives, in the locomotive high-speed cruising process, can produce sizable vibration, vibration can cause the loosening of some sealing positions, for the oil-hole cover device on the installing locomotive gear cases, adopt screw threads for fastening to cooperate between present port lid and the port lid seat, thereby loosening taking off produce that to reveal be inevitable under long-term vibration.In addition, existing oil-hole cover device, the small-bore can only be used to the machine oil of annotating, and be equipped with dipstick; Wide-aperturely be used to install additional grease but do not have dipstick function, function singleness.
The utility model content
The purpose of this utility model is to provide a kind of large aperture oil-hole cover device, to eliminate the phenomenon that gets loose of port lid.
To achieve these goals, the technical solution of the utility model is to adopt a kind of large aperture oil-hole cover device, be made of port lid base and port lid, port lid revolves an engaging support mechanism by a cover elasticity that is arranged at port lid and port lid base upper port place and is assemblied on the port lid base.
Described elasticity is revolved an engaging support mechanism by the Handle axis that endwisely slips on the port lid and install, the retracing spring of port lid right-hand side arbor upper sleeve through, the radially fixing limited bolt that assembles on the port lid inner handle shaft, also respectively be provided with a position-limited trough below two sections isometric, the symmetrical spacing muscle formations that cooperate with limited bolt of fixing on the inwall of port lid base port, two sections spacing muscle.
Described port lid inner handle shaft is provided with axial dipstick.
Because it is that elasticity is revolved an engaging support mechanism that the utility model changes screw-tightened, make port lid once being rotated in place, just fastened and by locked, thereby eliminated the phenomenon that gets loose that vibration brings, played the effect of good oil plant leak-stopping, reduced the consumption of lubricating oil of gear case, improved the reliability of locomotive operation, certain social meaning and economic benefit have been arranged.The large aperture design both can be used for installing additional grease, can be used for installing additional machine oil again.What of oil mass in the casing the axial dipstick that is provided with on the port lid inner handle shaft can also measure, diverse in function, and comformability is strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a mechanism of action scheme drawing of the present utility model;
Fig. 3 is the expansion scheme drawing of the utility model cage port.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, large aperture of the present utility model oil-hole cover device is made of port lid base 4 and port lid 2, and port lid 2 revolves an engaging support mechanism by a cover elasticity that is arranged at port lid 2 and port lid base 4 upper port places and is assemblied on the port lid base.The elasticity of present embodiment is revolved an engaging support mechanism by the Handle axis 8 that endwisely slips on the port lid 2 and install, the retracing spring 9 of port lid 2 right-hand side arbors 8 upper sleeve throughs, the radially fixing limited bolt 5 that assembles on port lid 2 inner handle shafts 8, also respectively be provided with a position-limited trough 10 below two sections isometric, symmetrical spacing muscle that cooperate with limited bolt 5,3 formations of fixing on the port lid base 4 port inwalls, two sections spacing muscle.One side of position-limited trough 10 is provided with block 7.Port lid 2 inner handle shafts 8 are provided with axial dipstick 6.
During use, two breach 11 between the spacing muscle 3 of two sections of limited bolt 5 alignings of radially fixing assembling on port lid 2 inner handle shafts 8, cover port lid 2, depressing handle 1 then makes limited bolt 5 be lower than spacing muscle 3 bottom surfaces, rotate a certain angle again, make limited bolt 5 aim at two sections two position-limited troughs 10 below the spacing muscle 3, loosing one's grip gets final product snap lock.
Claims (3)
1, a kind of large aperture oil-hole cover device is made of port lid base and port lid, it is characterized in that, port lid revolves an engaging support mechanism by a cover elasticity that is arranged at port lid and port lid base upper port place and is assemblied on the port lid base.
2, oil-hole cover device according to claim 1, it is characterized in that, described elasticity is revolved an engaging support mechanism by the Handle axis that endwisely slips on the port lid and install, the retracing spring of port lid right-hand side arbor upper sleeve through, the radially fixing limited bolt that assembles on the port lid inner handle shaft, also respectively be provided with a position-limited trough below two sections isometric, the symmetrical spacing muscle formations that cooperate with limited bolt of fixing on the inwall of port lid base port, two sections spacing muscle.
3, oil-hole cover device according to claim 2 is characterized in that, described port lid inner handle shaft is provided with axial dipstick.
