Summary of the invention
The utility model is to overcome above-mentioned defect of the prior art, there is provided one can adapt to the requirement of various engines assembling process flywheel locking, realize clutch and belt pulley tightening technique, simple to operate, save the artificial and flywheel locking frock of enhancing productivity.
Technical solution of the present utility model is such: a kind of flywheel locking frock, comprise support, gear, jackshaft, positioning stud, it is characterized in that, between gear (7) and support (6), jackshaft (8) is installed, support (6) two ends positioning stud (3) are fixed on bell housing (5) face, gear (7) engages with flywheel (2), support (6) is arranged on jackshaft (8) in the middle part of bracket bottom and gear (7), jackshaft (8) is fixed with gear (7), support (6) supports fixing jackshaft (8) and gear (7), jackshaft (8) and support (6), fixed by welding or key+interference fit between gear (7), support (6) is for fixing jackshaft (8) and gear (7), and be arranged on the bell housing (5) of engine, support (6) formulates length and locating slot according to the starter installing hole center on the bell housing (5) of engine, locating slot on support (6) is that the starter installing hole on the bell housing (5) according to engine is formulated, the groove width of locating slot is slightly larger than positioning stud (3) screw thread nominal diameter, positioning stud (3) is assemblied on the starter installing hole of bell housing (5) of engine by locating slot, jackshaft (8) center respectively with support (6) supporting surface center, gear (7) reference circle central alignment is fixed.
Positioning stud (3) screw thread nominal diameter is consistent with the screw thread nominal diameter of starter installing hole.
Jackshaft (8) is for connection bracket (6) and gear (7), and jackshaft (8) axis is respectively perpendicular to support (6) supporting surface and gear (7) side.
The length of jackshaft (8) equals the distance of the starter installed surface on the bell housing (5) of engine to the nearest side of engine flywheel.
The upper fixed gear (7) of jackshaft (8), the flywheel gear teeth meshing of gear (7) and engine, the wheel tooth module of gear (7) is consistent with the starter driving gear that engine assembles, and gear (7) is the imperfect gear that a complete gear wheel or the number of teeth are no less than 3.
Compared with prior art, the beneficial effects of the utility model are:
1, utilize this flywheel locking frock locking engine assembly process to rotate, realize the object of clutch and belt pulley securing member screw-down torque.
2, utilize flywheel locking frock to save a large amount of artificial, and simplify the operation, reduce special equipment, reduce manufacturing cost.
3, starter installed surface and installing hole on engine is utilized to locate and fix, easy to operate, and then enhance productivity.
4, the starter driving gear scrapped can be utilized to carry out making frock, frock making cost is low.
5, this frock can be applicable to the assembling of engine gear case train, increases work efficiency further.
6, this frock can be applicable to the engine rotation locking work of maintenance process.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiment of the utility model patent is described in detail, but is to be understood that the protection domain of the utility model patent is not by the restriction of detailed description of the invention.
Embodiment, a kind of flywheel locking frock, support (6) is arranged on jackshaft (8) in the middle part of described bracket bottom and gear (7), jackshaft (8) with between support (6), gear (7) by weld or key+interference fit is fixed.Gu timing demands jackshaft (8) center respectively with support (6) supporting surface center, gear (7) reference circle central alignment.Support (6) is that length and locating slot are formulated in the starter installing hole center on bell housing (5) (or bell housing, the transfer case etc.) according to engine, and the groove width of locating slot is slightly larger than positioning stud (bolt) screw thread nominal diameter.The length of jackshaft (8) equals the distance of the starter installed surface on engine bell housing (5) (or bell housing, transfer case etc.) to the nearest side of engine flywheel.The wheel tooth module of gear (7) is consistent with the starter driving gear that engine assembles, and directly can use the driven wheel of the starter that engine assembles; Can be a complete gear wheel, also can be the imperfect gear that the number of teeth is no less than 3.
During work, flywheel locking frock (1) is installed on engine bell housing (5) (or bell housing, transfer case etc.), the gear (7) of flywheel locking frock (1) is allowed to engage with the flywheel (2) of engine, rotary flywheel locking frock (1) again, allow the screw of the locating slot of flywheel locking frock (1) and bell housing (5) align, then positioning stud (3) (or bolt) is assemblied on the starter installing hole of bell housing (5) of engine by locating slot.So far flywheel locking frock (1) installs, and locking flywheel, engine crankshaft (4) can not rotate, and then realize the object of clutch and belt pulley securing member screw-down torque.
Be only the more excellent specific embodiment of the utility model patent above, but the utility model patent is not limited thereto, the changes that any person skilled in the art can think of all should fall into the protection domain of the utility model patent.
