Abstract

The utility model discloses a universal connecting shaft, comprising a roller-end connector and a bearing gland which are connected together by a bolt, wherein a thrust pin is connected between the bolt and the bearing gland; one end of the thrust pin is arranged in a pin hole on a bolt head, and the other end thereof is arranged in a pin hole on the bearing gland; and the thrust pin is axially provided with a thread through hole. In the utility model, the thrust pin is axially arranged between the bolt and the bearing gland to fasten the bolt so as to prevent looseness of the universal connecting shaft due to the axial thrust of the bolt in the using and moving process, thus changing the mode of anti-loosening for a connecting bolt of the bearing gland in the traditional structure, and effectively guaranteeing the working performance and service life of the universal connecting shaft; and simultaneously, after being axially provided with the thread through hole, the thrust pin can be easily and rapidly ejected by a tool bolt or a screw, so the universal connecting shaft is very convenient to dismantle and maintain.

Description

A kind of universal-joint spindle

Technical field

The utility model relates to a kind of universal-joint spindle, particularly relates to the universal-joint spindle that comes the connection bearing gland by bolt.

Background technique

When assembling with bearing gland, adopt by the roller end joint of universal-joint spindle bolt to be connected usually, connecting bolt often is subjected to bigger end thrust in the use movement process of universal-joint spindle, loosening in order to prevent retreating of bolt, at present take to be provided with the method for locking pressing plate mostly in the bolt head end, but its structure is comparatively complicated, installation and removal are equal inconvenient, and the pressing plate of axially installing also inefficacy easily under the effect of long-term end thrust, thereby easily cause whole universal-joint spindle impaired.

The model utility content

Technical problem to be solved in the utility model provide a kind of bearing gland connecting bolt fixing reliable, be difficult for that pine moves back, universal-joint spindle easy to loading and unloading.

In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of universal-joint spindle, comprise the roller end joint and the bearing gland that link together by bolt, be connected with thrust pin between described bolt and the bearing gland, one end of described thrust pin is assemblied in the pin-and-hole on the bolt head, the other end is assemblied in the pin-and-hole on the bearing gland, and described thrust pin axially offers tapped through hole.

A kind of universal-joint spindle of the utility model, come clamping bolt by the mode that between bolt and bearing gland, thrust pin radially is set along bolt, to prevent that universal-joint spindle bolt in using movement process from moving back because of being subjected to the end thrust pine, changed and in the conventional construction bearing gland connecting bolt has been carried out locking mode, effectively guaranteed the service behaviour and the working life of universal-joint spindle; Simultaneously, thrust pin can easily fast eject thrust pin by instrument bolt or screw after axially offering tapped through hole, very is convenient to universal-joint spindle is carried out demolition and maintenance.A kind of universal-joint spindle of the utility model, architecture advances is simple and practical, has both reduced its manufacturing cost, has improved its working life again, has good market value.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of a kind of universal-joint spindle of the utility model.

Fig. 2 is the partial sectional view of a kind of universal-joint spindle of the utility model.

Fig. 3 is the structural representation of the bolt in the utility model.

Fig. 4 is the structural representation of the bearing gland in the utility model.

Fig. 5 is the structural representation of the thrust pin in the utility model.

Wherein, reference character: 1 is bolt, and 2 is the roller end joint, and 3 is bearing gland, and 4 is thrust pin, and 5 is bolt head, and 6 is pin-and-hole, and 7 is pin-and-hole, and 8 is tapped through hole.

Embodiment

Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.

Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, a kind of universal-joint spindle of the utility model, comprise roller end joint 2 and bearing gland 3, the two is involutory with the toe joint form, and the bearing gland 2 after involutory also is fixed together by many bolts 1 that are distributed on the same circumference.In order to prevent that universal-joint spindle bolt in using movement process from moving back because of being subjected to the end thrust pine, also be connected with thrust pin 4 between every bolt 1 and the bearing gland 3, one end of its thrust pin 4 is assemblied in the pin-and-hole 6 on the bolt head 5, the other end is assemblied in the pin-and-hole 7 on the bearing gland 3, big coaxial lines such as pin-and-hole 6 on the bolt head 5 and 7 need of the pin-and-hole on the bearing gland 3, the thrust size that the quantity of thrust pin 4, size, material should be subjected to according to size and its of universal-joint spindle designs.Thrust pin 4 axially offers tapped through hole 8, when needs withdraw from thrust pin 4 with dismounting bearing gland 3, only needs supporting bolt or screw are screwed in the tapped through hole 8, and thrust pin 4 can easily eject under the opposition of bolt or screw.Its size of tapped through hole 8 is preferably come matching design according to the universal standard of bolt or screw on the thrust pin 4, when adopting instrument bolt or screw that thrust pin is withdrawed from, can operate by direct selection standard spare like this, move back the pin instrument and need not to process special use in addition separately.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.

Claims

1. universal-joint spindle, comprise the roller end joint (2) and the bearing gland (3) that link together by bolt (1), it is characterized in that: be connected with thrust pin (4) between described bolt (1) and the bearing gland (3), one end of described thrust pin (4) is assemblied in the pin-and-hole (6) on the bolt head (5), the other end is assemblied in the pin-and-hole (7) on the bearing gland (3), and described thrust pin (4) axially offers tapped through hole (8).
