Abstract
A coupling device for a hollow shaft body and a transmission tray comprises a hollow shaft body, a transmission tray and a fastening bolt. The hollow shaft body and the transmission tray are of end-tooth connection structure, between which an end-tooth tray consisting of a left and a right end-tooth tray meshing combined together is arranged for connection. The left end-tooth tray combines the transmission hollow shaft body into one body and the right end-tooth tray combines the transmission tray into one body. The left and the right end-tooth trays teeth are of mutually matched tooth shape and distributed radially and evenly on the end face of the hollow shaft body and the transmission tray to form annular teeth with a ladder section. The fastening bolt is used for tightly connecting the transmission hollow shaft body and the transmission tray.
Description
Technical field
The utility model relates to a kind of connecting structure of locomotive component, refers in particular to a kind of wheel that adopts to the drive sleeve axle body of the locomotive of hollow axle driving system and the connecting structure of drive plate, is mainly used in the various drive sleeves that hollow shaft driven locomotive of taking turns.
Background technique
Drive sleeve is to adopt the vitals of wheel to the hollow axle driving system locomotive, and it is right to be mainly used to that the gear-box output torque is passed to wheel.Drive sleeve generally is made up of axle body and drive plate, because hollow shaft needs parts such as mounting teeth roller box outward, drive sleeve axle body and drive plate adopt and divide body structure.At present adopt attachment pegs to connect between drive sleeve axle body and the drive plate, attachment pegs and hollow shaft interference assembling are generally shunk the back with attachment pegs with cooled with liquid nitrogen during installation and are installed, taking-up after must connecting pin during repair demolition destroying.Axle body is that production effectiveness is low with the major defect that drive plate adopts attachment pegs to connect, and installation and removal are extremely inconvenient, and dismounting has destructiveness, consumable material.Therefore be necessary the connecting structure of drive sleeve axle body and drive plate is improved.
The model utility content
The purpose of this utility model is at the deficiency of existing drive sleeve axle body with the connecting structure of drive plate, proposes a kind of production and renders a service highly, mounts and dismounts the utmost point connecting structure of drive sleeve axle body and drive plate easily.Eliminated and adopted pin to connect and the manufacturing process of necessary cooling pin Fix ﹠ Destroy pin dismounting, improved the installation precision of axle body and drive plate, simplified the technology of axle body and the installation and removal of drive plate, improved the production effectiveness of installing/dismounting, and the saving material.
The purpose of this utility model is achieved through the following technical solutions:
The coupling gear of a kind of drive sleeve axle body and drive plate comprises hollow shaft axle body, drive plate and clamping bolt.Drive sleeve axle body and drive plate are the end tooth connecting structure, and an end-toothed disc that is used to connect drive sleeve axle body and drive plate is arranged between drive sleeve axle body and drive plate, are made up of left end fluted disc, the engagement of right-hand member fluted disc.Left end fluted disc and drive sleeve axle body are connected as a single entity, and right-hand member fluted disc and drive plate are connected as a single entity, and the teeth of left end fluted disc, right-hand member fluted disc are the profiles of tooth that matches mutually; Left end fluted disc, right-hand member fluted disc teeth are on the radial end face that is uniformly distributed in drive sleeve axle body and drive plate, evenly are distributed as the ring-type teeth, and the teeth section is trapezoidal; For guaranteeing the end-toothed disc normal engaged, between drive sleeve axle body and drive plate, carry out fastening connection with clamping bolt.
The utility model compared with prior art has following advantage, characteristics or good effect.
1, easy installation and removal, the installing/dismounting between axle body and the drive plate are the installing/dismounting of attachment bolt, produce and render a service height;
2, linking intensity height, owing to there is not middle force-transmitting member, the transmission of moment of torsion is the transmission of power between tooth and the tooth, and the number of teeth is many, and is evenly distributed at end face, and each tooth power transmission is evenly distributed, and can transmit than high pulling torque;
3, connect the precision height, the design of end tooth has automatic centering, improves the installation coaxality of drive plate and axle body.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
From accompanying drawing as can be seen, the utility model is the coupling gear of a kind of drive sleeve axle body and drive plate.Comprise hollow shaft axle body 1, drive plate 2 and clamping bolt 3.Drive sleeve axle body 1 be the end tooth connecting structure with drive plate 2, and an end-toothed disc 4 (shown in Figure 2) that is used to connect drive sleeve axle body 1 and drive plate 2 is arranged between drive sleeve axle body 1 and drive plate 2, is meshed by left end fluted disc, right-hand member fluted disc and forms.Left end fluted disc and drive sleeve axle body 1 are connected as a single entity, and right-hand member fluted disc and drive plate 2 are connected as a single entity, and the teeth of left end fluted disc, right-hand member fluted disc are the profiles of tooth that matches mutually; Left end fluted disc, right-hand member fluted disc teeth are on the radial end face that is uniformly distributed in drive sleeve axle body 1 and drive plate 2, evenly are distributed as the ring-type teeth, and the teeth section is trapezoidal.For guaranteeing the end-toothed disc normal engaged, between drive sleeve axle body 1 and drive plate 2, carry out fastening connection with clamping bolt 3.
Claims (4)
1. the coupling gear of hollow shaft axle body and drive plate, comprise hollow shaft axle body, drive plate and clamping bolt, it is characterized in that: drive sleeve axle body and drive plate are the end tooth connecting structure, and an end-toothed disc that is used to connect drive sleeve axle body and drive plate is arranged between drive sleeve axle body and drive plate.
