Abstract
The utility model discloses a coupler increasing gear with a guide angle, which comprises a gear body and a gear shaft. The coupler increasing gear with the guide angle is characterized in that the gear shaft is a taper gear shaft; the gear body is provided with a taper gear bore matched with the taper gear shaft; the outlet of one end of the taper gear bore is provided with a beveled edge; the beveled edge and the direction on which the bore wall of the taper gear bore form the guide angle; the taper gear shaft is provided with a tool withdrawal groove matched with the length of the transverse edge of the guide angle of the taper gear bore; and one side of the tool withdrawal groove is provided with a retaining shaft matched with the diameter of one end of the taper gear bore, which is provided with the guide angle. After the gear disclosed by the utility model is improved, the labor intensity for experienced workers to assemble the coupler gear is lowered, and the time for assembling a coupler is shortened; and meanwhile, the gear body and the gear shaft can be prevented from being damaged in the gear assembling and disassembling process. The coupler increasing gear has a simple structure and lower cost and is very practical.
Description
Technical field
The utility model relates to a kind of overdrive gear, and is particularly related to the coupler overdrive gear at tape guide angle.
Background technique
At present, fluid coupling is widely used in the electric boiler feed system.In the acceleration type fluid coupling, be provided with a pair of overdrive gear, overdrive gear body and gear shaft adopt no key interference fit, with the form of hydraulic pressure suit gear mass are fixed on the gear shaft.The overdrive gear body comes transmitting torque by itself and Gear Axle Over-surplus amount.In the equipment process of gear mass and gear shaft, often the outer surface of appearance axle and bore are caused axle and gear rework part to increase by the phenomenon of plucking, delay man-hour, influence efficiency of assembling.
The model utility content
The purpose of this utility model is to provide the coupler overdrive gear at a kind of tape guide angle, has the coupler overdrive gear now in the process that gear and axle are equipped to overcome, and often the outer surface of appearance axle and bore are by the defective of plucking.
The problem that the utility model solved can realize by the following technical solutions:
The coupler overdrive gear at tape guide angle, comprise: gear mass, gear shaft, it is characterized in that: described gear shaft is a conical tooth wheel shaft, described gear mass is provided with the angular wheel endoporus that matches with this conical tooth wheel shaft, the outlet port of described angular wheel endoporus one end is provided with a hypotenuse, the direction at the hole wall place of described hypotenuse and angular wheel endoporus constitutes angle of deflection, described conical tooth wheel shaft is provided with the tool withdrawal groove that the horizontal edge length with the angle of deflection of described angular wheel endoporus matches, and is provided with described angular wheel endoporus in a side of tool withdrawal groove to have the shoulder block that the diameter of angle of deflection one end matches.
The angle of the angle of deflection of described angular wheel endoporus is smaller or equal to 15 °.
The diameter of described shoulder block has the diameter of angle of deflection one end more than or equal to the angular wheel endoporus.
Beneficial effect: after the utility model improves gear, reduced the labor intensity that the master worker assembles the coupler gear, shortened the installation time of coupler.Simultaneously, in the gear assembling and dissembling process, avoided the damage of gear mass and gear shaft, the utility model is simple in structure, need not what cost, and is very practical.Through a large amount of facts have proved, above-mentioned improvement is effective.
Description of drawings
Fig. 1 is the cross-sectional view of the coupler overdrive gear at the utility model tape guide angle.
Fig. 2 is the structure for amplifying schematic representation of tool withdrawal groove of the coupler overdrive gear at the utility model tape guide angle.
Fig. 3 is the structure for amplifying schematic representation of angle of deflection of the coupler overdrive gear at the utility model tape guide angle.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, described gear shaft 2 is a conical tooth wheel shaft, described gear mass 1 is provided with the angular wheel endoporus 4 that matches with this conical tooth wheel shaft 2, one end of described angular wheel endoporus 4 is provided with angle of deflection 5, described conical tooth wheel shaft 2 is provided with the tool withdrawal groove 3 that the angle of deflection 5 with described angular wheel endoporus 4 matches, and is provided with the shoulder block 6 that the diameter with the angle of deflection 5 of described angular wheel endoporus 4 matches in a side of tool withdrawal groove 3.
Referring to Fig. 2,3, the length of described tool withdrawal groove 3 is a1, the length of described angle of deflection 5 horizontal edges is a, the length of angle of deflection 5 vertical edges is b, the length of angle of deflection horizontal edge is a according to the length of tool withdrawal groove 3 is that a1 is tentatively definite, guarantee a 〉=a1 by the tolerance range of determining a, the length of angle of deflection 5 vertical edges is the b determining dimensions: tentatively definite with the maximum interference amount of gear shaft 2 according to gear mass 1.The angle of described angle of deflection is α, tentatively derives angle of deflection α according to cosine formula tag (α)=b/a.Angle [alpha] to angle of deflection is adjusted, but will guarantee angle of deflection angle [alpha]≤15 °.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
