Abstract

Disclosed is an axially inserted turning mechanism which comprises a bracket shaft (1). The utility model is characterized in that the bracket shaft (1) is sleeved with a top disc (2), a centre (3) on the top disc (2) is positioned inside a hole (4) opened on the bracket shaft (1), the position of a travel switch (5) is opposite to the position of the centre (3), and a turning gear (7) capable of being meshed with a starting gear (6) is sleeved on the bracket shaft (1) and can move axially. The axially inserted turning mechanism is simple in structure, small in volume, light in weight, convenient in maintenance, simple and easy in operation, convenient in assembly and disassembly and good in usage effects.

Description

Axial plug-in type barring mechanism

Technical field:

The utility model relates to a kind of barring mechanism, and especially a kind of simple in structure, volume is little, in light weight, and care and maintenance is convenient, operate simple and easy, the axial plug-in type barring mechanism that easy accessibility and using effect are good.

Background technique:

When diesel engine need carry out jiggering, turbine and worm formula or eccentricity gear formula barring mechanism are put in general overhead turbine and worm formula, the side of adopting, these three kinds of barring mechanisms all are radially engagement type, existing problem is: its overall structure and operation are comparatively complicated, volume is big, Heavy Weight, and need regularly it to be carried out care and maintenance work, and then improved cost; And space required when dismantling, installing and operating is bigger, and the process-cycle is longer.

Summary of the invention:

The utility model is in order to solve existing in prior technology the problems referred to above, to provide a kind of simple in structure, and volume is little, in light weight, and care and maintenance is convenient, operate simple and easy, the axial plug-in type barring mechanism that easy accessibility and using effect are good.

Technical solution of the present utility model is: a kind of axial plug-in type barring mechanism, comprise support shaft 1, it is characterized in that: be socketed with 2 on the support shaft 1, take over a business top 3 on 2 and be positioned at the hole 4 that is opened on the support shaft 1, the position of position limit switch 5 is relative with top 3, the jiggering gear 7 that can be meshed with starter receiver 6 is socketed on the support shaft 1, and can move axially.

Described support shaft 1 is provided with locating stud 8.

The utility model is compared with prior art, has following advantage:

Structure of this device and operation are all very simple, and volume is little, in light weight, and jiggering gear, the locating stud that uses as the jiggering tool combinations and taking over a business etc. all needs care and maintenance hardly, and then reduced cost; And the process-cycle is shorter, is easy to apply.

Description of drawings:

Fig. 1 is the utility model embodiment's an original state schematic representation.

Fig. 2 is the utility model embodiment's a working state schematic representation.

Embodiment:

Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1 and Figure 2: a kind of axial plug-in type barring mechanism, comprise support shaft 1, on support shaft 1, be socketed with 2, take over a business 2 can support shaft 1 axially on move; Offer porosely 4 on support shaft 1, be arranged on top 3 on 2 and pass hole 4, position limit switch 5 is positioned at 4 positions, hole, when top 3 stretch out from hole 4, can contact with position limit switch 5 just; The jiggering gear 7 that can be meshed with starter receiver 6 is socketed on the support shaft 1, and can do axial motion on support shaft 1; Also be provided with locating stud 8 on support shaft 1, after jiggering gear 7 both was in fixed position, locating stud 8 can be located, locked.

In the time of need carrying out jiggering, at first will take over a business 2 and jiggering gear 7 order be enclosed within on the support shaft 1, and make top 3 to be positioned at hole 4; Then support shaft 1 is fixed in place, the jiggering gear 7 and the starter receiver 6 that are connected above the support shaft 1 can be meshing with each other; Promote jiggering gear 7, make it to mesh fully, and utilize locating stud 8 that it is locked into starter receiver; Pass hole 4 this moment top 3, withstands on the position limit switch 5, and position limit switch 5 control diesel engine self-lockings can not start; Utilize ratchet wrench rolling disc skiving wheel 7, make it to rotate, and then drive starter receiver 6, carry out jiggering;

After jiggering is finished, unload locating stud 8, jiggering gear 7 and take over a business 2 also preservations, wait until to use next time getting final product.

Claims

1, a kind of axial plug-in type barring mechanism, comprise support shaft (1), it is characterized in that: support shaft is socketed with (2) on (1), top (3) of taking over a business on (2) are positioned at the hole (4) that is opened on the support shaft (1), the position of position limit switch (5) is relative with top (3), the jiggering gear (7) that can be meshed with starter receiver (6) is socketed on the support shaft (1), and can move axially.

2, axial plug-in type barring mechanism according to claim 1, it is characterized in that: described support shaft (1) is provided with locating stud (8).
