Abstract
The invention discloses a kind of crankshaft timing gear and install detent mechanism, comprising: timing gears positioning spline, it is located at timing gears and installs on end face; Positioning tool, it has front end locating detent, interfix pawl, rear end locating detent and backstay, the setting position of backstay is the phase coincidence with the crankshaft pin top dead centre of engine rearmost end one cylinder, and front and back ends locating detent contacts with corresponding main bearing journal, the pawl of interfix simultaneously contacts with crankshaft pin; Timing gears are assemblied in crankshaft rear end and positioning spline to be aimed at the described backstay on positioning tool and installed through hot pressing.The present invention to be alignd with the detent on timing gears by positioning tool and coordinates, and both can ensure that timing is located, can ensure that again structure is simple, easy to process.
Description
Technical field
The present invention relates to engine art, particularly a kind of Diesel engine crankshaft timing gear installs detent mechanism.
Background technology
The function of engine crankshaft timing gear, except carry-over moment, also will meet fuel feeding and valve timing, therefore must ensure the installation phase place of notch when assembling.When the rearmounted assembling of timing gears (being arranged on crankshaft rear end face), timing gears are generally positioned by the pin-and-hole on its end face and the pin be assemblied on crankshaft rear end face, or are located by auxiliary tooling device.
When adopting the mechanism of pin-and-hole and alignment pin to position, require that bent axle and timing gears installed surface are all reserved with enough spaces and come locating and machining pin and dowel hole.And space is little on bent axle fitting surface, not easily process a dowel hole.For the installation location of crankshaft timing gear both can be ensured, processing can be convenient to again, be badly in need of a kind of installation detent mechanism of timing gears of improvement.
Summary of the invention
The present invention is to overcome defect in above-mentioned prior art, and being alignd with the detent on timing gears by special positioning tool is coordinated, and both can ensure that timing is located, can ensure that again structure is simple, easy to process.
For achieving the above object, the invention provides a kind of crankshaft timing gear and install detent mechanism, comprising: timing gears positioning spline, it is located at timing gears and installs on end face; Positioning tool, it has front end locating detent, interfix pawl, rear end locating detent and backstay, the setting position of backstay is the phase coincidence with the crankshaft pin top dead centre of engine rearmost end one cylinder, and front and back ends locating detent contacts with corresponding main bearing journal, the pawl of interfix simultaneously contacts with crankshaft pin; Timing gears are assemblied in crankshaft rear end and positioning spline to be aimed at the described backstay on positioning tool and installed through hot pressing.
In technique scheme, the width of timing gears positioning spline can be 3-5mm, and the degree of depth can be 3-5mm.
Compared with prior art, the present invention has following beneficial effect:
The present invention adopts the backstay of positioning tool to coordinate with the positioning spline of timing gears and locates, and structure is simple, easy to process, can ensure that timing gears locate simple and easy and registration when hot pressing is assembled.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
As shown in Figures 1 to 4, the timing gears 1 that the present invention relates to are arranged on the rear end face of bent axle, the installation end face of these timing gears and bent axle offer a positioning spline 11.The width design of positioning spline 11 is 3-5mm, and the keyway degree of depth is 3-5mm.
Further as Figure 4-Figure 6, present invention eliminates alignment pin in prior art, dowel hole carries out the locate mode that coordinates, replace the mode that positioning tool 2 and timing gears positioning spline 11 coordinate location.Positioning tool 2 of the present invention comprises front end locating detent 24, interfix pawl 23, rear end locating detent 22 and backstay 21, when timing gears install location, the backstay of this positioning tool 2 is overlapped with last cylinder crankshaft crank-pin top stopping point, as shown in Figure 6, now, the front end locating detent 24 of positioning tool 2 contacts with two trunnions 34 with rear end locating detent 22, and interfix pawl 23 contacts with a crank-pin 33.Maintain the position of this positioning tool 2, timing gears 1 are assembled to (namely by being heated to uniform temperature) on crankshaft rear end face through hot pressing, make the positioning spline 11 of timing gears just to the backstay 21 of positioning tool 2 simultaneously, form the interference fit of timing gears 1 and bent axle 3 rear end.
The present invention adopts the backstay of positioning tool to coordinate with the positioning spline of timing gears and locates, and structure is simple, easy to process, can ensure that timing gears locate simple and easy and registration when hot pressing is assembled.
Be only a specific embodiment of the present invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
