Abstract
The invention discloses a connecting structure for a crankshaft gear, solving the problem of inconvenient gear changing. The technical solution is as follows: an inner hole of a gear (5) and a pin hole (6) on an end surface of a crankshaft (2) are provided with pins (1) which are positioned by the inner hole of the gear (5) and the pin hole (6) on the end surface of the crankshaft (2); the end surface of the gear (5) is drilled with proper amount of bolt holes; an end surface of the crankshaft (2) corresponding to the bolt holes on the end surface of the gear (5) is drilled with nine bolt holes as many as those on the end surface; bolts (3) pass through the bolt holes for fixing the gear (5) to the end surface of the crankshaft (2); pre-tightening force is generated after the bolt 3 is screwed up; and the end surface of the gear 5 and a locating surface of the crankshaft 2 generate the friction for transmitting the power. The connecting structure is convenient in installation, compact in structure, short in maintaining period, and low in cost.
Description
Technical field
The present invention relates to motor transmission part linkage structure, be specifically related to a kind of linkage structure of crankshaft gear.
Background technique
The Placement that generally adopts the axial plane interference that is connected of crankshaft gear and bent axle, this Placement need heat gear and be sleeved on the bent axle on the heating plant of special use, utilize to cooperate axial plane generation distortion formation friction to come transferring power, assembly method is loaded down with trivial details, and efficient is low; And crankshaft gear lost efficacy, and dismantle the back, very inconvenience of maintenance.
Summary of the invention
The present invention discloses a kind of linkage structure of crankshaft gear, can be fast gear changing more, address the above problem.Concrete technical measures are at gear (5) endoporus and bent axle (2) end face pin-and-hole (6) mount pin (1), and bolt (3) is connected gear (5) with bent axle (2).
The end face of described gear (5) bores the moderate bolt hole of quantity, bores the bolt hole of equal number at the bolt hole relative position of bent axle (2) end face and gear (5) end face.
Described number of bolt hole is nine.
The present invention is easy for installation, compact structure, service cycle is short, cost is low.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the long splice composition of crankshaft gear;
Fig. 2 is the crankshaft gear end view drawing.
Among the figure: pin 1, bent axle 2, bolt 3, locating face 4, gear 5, pin-and-hole 6.
Embodiment
As shown in Figure 1, the linkage structure of crankshaft gear is a mount pin 1 in the endoporus of gear 5 and bent axle 2 end face pin-and-holes 6, with gear 5 endoporus and bent axle 2 end face pin-and-holes 6 location; Gear 5 and bent axle 2 are coupled together through bolt hole with bolt 3; See Fig. 2, the end face of gear 5 bores the moderate bolt hole of quantity, can bore nine bolts hole, passing bolt hole with bolt 3 is fixed on gear 5 on bent axle 2 end faces, bolt 3 is tightened the back and is produced pretightening force, and under the effect of pretightening force, gear 5 end faces and bent axle 2 locating faces produce friction, transferring power, gear 5 just can drive the gear that is engaged with and rotate.
Claims (3)
1. the linkage structure of a crankshaft gear, it is characterized in that: described linkage structure is at gear (5) endoporus and bent axle (2) end face pin-and-hole (6) mount pin (1), and bolt (3) is connected gear (5) with bent axle (2).
2. according to the linkage structure of the described crankshaft gear of claim 1, it is characterized in that: the end face of described gear (5) bores the moderate bolt hole of quantity, bores the bolt hole of equal number at the bolt hole relative position of bent axle (2) end face and gear (5) end face.
3. according to the linkage structure of the described crankshaft gear of claim 2, it is characterized in that: described number of bolt hole is nine.
