Abstract
The utility model discloses a locking structure of an engine front fan shaft. The locking structure of the engine front fan shaft comprises a transition cushion plate, a fan shaft, a locking block and installation bolts and is characterized in that proper space is designed between a fitting surface of the fan shaft and the transition cushion plate. The transition cushion plate is fixed on a cylinder head through two through holes which are arranged in the transition cushion plate, and two below threaded holes are used for supporting a fan shaft installation bolt in transition mode and meanwhile for adjusting height of the fan shaft in different gear trains. A locking plate is designed to be provided with an external thread and an internal through hole and used for locking the fan shaft, and meanwhile the bolts are connected to the transition cushion plate in cushion block mode. The locking structure of the engine front fan shaft is compact in structure, convenient to spatially arrange, and easy to assemble and disassemble. Thus second assembly and disassembly of a cylinder head bolt are avoided, and failure rate of three leakages is effectively reduced.
Description
Technical field
The utility model relates to a kind of motor head fan shaft locking mechanism, and particularly a kind of cylinder bolt is exempted from the fan shaft locking mechanism of secondary disassembly-type.
Background technique
At present, the motor head part is supporting day by day numerous and diverse, part motor head compact structure, need to support a fan shaft construction bolt by two cylinder head bolt hole transition, need rationally fan attachment axle of secondary dismounting cylinder head bolt when causing this structure to install, very easily cause the cylinder head water leakage fault to occur.Therefore be badly in need of a kind of simple in structurely, can effectively avoid again the fan shaft locking mechanism of secondary dismounting cylinder head construction bolt.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes in the above-mentioned technology, it is a kind of simple in structure that purpose is to provide, easy accessibility, the locking mechanism of avoiding the cylinder head bolt secondary to dismantle are applicable to the supporting a kind of motor head fan shaft locking mechanism of all kinds of motors.
Technical solution of the present utility model is such: a kind of motor head fan shaft locking mechanism, comprise transition backing plate, fan shaft, latch, construction bolt, it is characterized in that the latch outside thread is installed in fan shaft endoporus and intermeshing, construction bolt passes the latch endoporus and is connected with the transition backing plate.
Gapped between fan shaft and the transition backing plate.
The latch external diameter has screw thread, inside center hole through hole.
The mounting hole of fan shaft is tapped hole.
Advantage of the present utility model has: 1, installation and removal mode is simple.2, avoid the secondary dismounting of cylinder head bolt.3, compact structure, the space arrangement convenience.4, effectively reduce by three and leak rate of fault.
Description of drawings
It is such that structure of the present utility model consists of:
Fig. 1 is the partial sectional view of the fan shaft locking mode structure of a kind of motor head fan shaft of the utility model locking mechanism.
Fig. 2 is the backing plate outline drawing of a kind of motor head fan shaft of the utility model locking mechanism.
Fig. 3 is the latch outline drawing of a kind of motor head fan shaft of the utility model locking mechanism.
Among Fig. 1～Fig. 3, transition backing plate (1), fan shaft (2), latch (3), construction bolt (4).
Embodiment
Most preferred embodiment of the present utility model is such, and with reference to accompanying drawing, a kind of motor head fan shaft locking mechanism comprises transition backing plate, fan shaft, latch, construction bolt.Top two holes of transition backing plate (1) are fixed in cylinder by cylinder head bolt and are covered, the below designs two tapped holes, be used for transition and support a fan shaft construction bolt (4), the adjusting (Fig. 1, Fig. 2) that is designed for different train fan axles (2) height of two tapped holes.Latch (3) is designed to external screw-thread, and the mode of interior bone is used for locking fan shaft (2), makes construction bolt (4) and transition backing plate (1) couple together (Fig. 1, Fig. 3) with the form of cushion block simultaneously.Between fan shaft (2) attachment face and transition backing plate (1), design appropriate gap, fan shaft (2) mounting hole is designed to tapped hole, use construction bolt (4) that fan shaft (2) is fixing in the time of by latch (3) locking fan shaft (2), guarantee and the coplane degree (Fig. 1) of fan shaft (2) with other part.Assembly method: first transition backing plate (1) is installed on the cylinder head, with fixing top two mounting holes of transition backing plate (1) of cylinder head bolt, fan shaft (2) is fixed on relevant position on the motor, locking block (3) is screwed into fan shaft (2) tapped hole, be screwed to transition backing plate (1) and contact, be installed on the transition backing plate (1) by latch (3) with construction bolt (4), will be tightened to form-fit torque on the construction bolt (4).
Above disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
Claims (4)
1. motor head fan shaft locking mechanism, comprise transition backing plate, fan shaft, latch, construction bolt, it is characterized in that latch (3) outside thread is installed in fan shaft (2) endoporus and intermeshing, construction bolt (4) passes latch (3) endoporus and is connected with transition backing plate (1).
2. according to a kind of motor head fan shaft locking mechanism claimed in claim 1, it is characterized in that between fan shaft (2) and the transition backing plate (1) gapped.
3. according to a kind of motor head fan shaft locking mechanism claimed in claim 1, it is characterized in that latch (3) external diameter has screw thread, inside center hole through hole.
4. according to a kind of motor head fan shaft locking mechanism claimed in claim 1, it is characterized in that the mounting hole of fan shaft (2) is tapped hole.
