Abstract
The utility model provides a mounting structure of a speed sensor, which is applied in the technical field of an engine. The mounting structure comprises a flywheel (2) connected with a crankshaft (1) of the engine as well as a speed sensor (3) arranged on a rear end surface (4) of a cylinder body of the engine, the speed sensor (3) is arranged closely to the flywheel (2), a flywheel side edge (5) of the flywheel (2) is provided with more than one signal teeth (6), and the speed sensor (3) is arranged closely to the flywheel side edge (5). The mounting structure is simple in structure, convenient in disassembling and assembling, can solve the problem of the measuring insensitivity of a speed signal and can guarantee the measuring accuracy of the speed signal; in addition, the time for the disassembling and the assembling is saved obviously, therefore, the efficiency of the disassembling and the assembling is improved.
Description
Technical field
The utility model belongs to technical field of engines, more particularly, relates to a kind of speed probe mounting structure.
Background technique
Now a lot of motors write down tach signal by signal panel, are that signal panel are installed on the bent axle, and sensor is in cylinder interior, and the high speed rotating by bent axle drives the rotation of signal panel and writes down tach signal.Such shortcoming is the very high requirement that is equipped with to signal panel, just may cause the inaccurate of signal in case very tiny deviation is installed; In case and signal panel have gone wrong, keep in repair very inconveniently, also bent axle to be removed could change.And this patent only need have been loaded onto sensor just at outer surface of cylinder block.
The model utility content
Technical problem to be solved in the utility model is: at the deficiencies in the prior art, provide a kind of simple in structure, can solve the speed probe mounting structure that tach signal is measured insensitive problem.
Solve above-described technical problem, the technological scheme that the utility model is taked is:
The utility model is a kind of speed probe mounting structure, comprise the flywheel that is connected with engine crankshaft, described speed probe mounting structure also comprises speed probe, described speed probe is installed on the engine cylinder-body ear end face, and described speed probe is set to the structure near flywheel.
On the flywheel edge of described flywheel more than one signal teeth is set, described speed probe is set to the structure near the flywheel edge.
Described signal teeth is set to be provided with along one week of flywheel edge the structure of the signal teeth of a plurality of projections.
Described speed probe is set to be movably arranged on the engine cylinder-body ear end face by the speed probe support.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
Speed probe mounting structure of the present utility model, simple in structure, easy accessibility, can solve tach signal and measure insensitive problem, and can guarantee the degree of accuracy of tachometric survey signal, and can obviously save the disassembly-and-assembly machine time, thereby the efficient of raising disassembly-and-assembly machine.
Description of drawings
Make briefly bright to each accompanying drawing of this specification expressed content and the mark among the figure below:
Fig. 1 is the positive TV structure intention of speed probe mounting structure described in the utility model;
Fig. 2 is the side-looking structure intention of the described speed probe mounting structure of Fig. 1;
Mark among the figure: 1, engine crankshaft; 2, flywheel; 3, speed probe; 4, engine cylinder-body ear end face; 5, flywheel edge; 6, signal teeth.
Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail embodiment:
Shown in accompanying drawing 1, accompanying drawing 2, the utility model is a kind of speed probe mounting structure, comprise the flywheel 2 that is connected with engine crankshaft 1, described speed probe mounting structure also comprises speed probe 3, described speed probe 3 is installed on the engine cylinder-body ear end face 4, and described speed probe 3 is set to the structure near flywheel 2.
More than one signal teeth 6 is set on the flywheel edge 5 of described flywheel 2, and described speed probe 3 is set to the structure near flywheel edge 5.
Described signal teeth 6 is set to be provided with along 5 one weeks of flywheel edge the structure of the signal teeth 6 of a plurality of projections.
Described speed probe 3 is set to be movably arranged on the engine cylinder-body ear end face 4 by speed probe support 7.
Structure of the present utility model is the signal teeth of a plurality of projectioies of arranging in the gap in the setting of the edge of flywheel, like this, in the engine rotation process, can be near the speed probe of flywheel by side face to signal teeth, thus reach the purpose of measuring engine speed.Because signal teeth is set directly on the flywheel, therefore avoided the not high problem of tachometric survey signal degree of accuracy that the structure of installation signal gear ring is brought on flywheel in the past.
Speed probe mounting structure of the present utility model, simple in structure, easy accessibility, can solve tach signal and measure insensitive problem, and can guarantee the degree of accuracy of tachometric survey signal, and can obviously save the disassembly-and-assembly machine time, thereby the efficient of raising disassembly-and-assembly machine.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or design of the present utility model and technological scheme are directly applied to other occasions without improving, all in protection domain of the present utility model.
