The novel roller end locating structure comprises a roller shaft head and a cross universal coupler roller end sleeve, wherein the roller shaft head and the cross universal coupler roller end sleeve are closely connected. Due to the structure, a short stress path rolling mill system can stably operate in a high-speed motion state and achieves the effect of a stable yield. Meanwhile, by adopting the structure, the system can be accelerated, and a yield increase becomes possible.

Description

A kind of novel roll end location structure

Technical field

The utility model relates to a kind of novel roll end location structure, specifically a kind of roll end location structure of using in the short stress bar line milling train of cross universal coupling transmission that adopts.

Background technology

The short stress bar line rolling machine system of the cross universal coupling transmission that prior art adopts, due to the design feature of cross universal coupling self, causes the significantly vibration of cross universal coupling in high-speed motion process.This vibration has worsened the working condition of short stress path rolling mill system, make short stress path rolling mill system cannot stable operation in higher speed of production, affected output.In order to solve the deficiencies in the prior art, the utility model proposes a kind of novel roll end location structure.

Utility model content

For the problems referred to above, the utility model aims to provide a kind of Novel rolling roller end location structure.

For realizing this technical purpose, scheme of the present utility model is: a kind of Novel rolling roller end location structure, comprises roll spindle nose, cross universal coupling roll end sleeve; Described roll and cross universal coupling sleeve couple together closely, effectively utilize the rigidity of roll, when cross universal coupling vibrates because of high-speed motion, by roll, better limit its amplitude, thereby alleviated vibration, made whole short stress path rolling mill system more stable under high-speed motion state.

As preferably, described roll spindle nose contains alignment pin.

As preferably, described cross universal coupling roll end sleeve contains locating hole.

The vibration that the purpose of this utility model produces while being to alleviate cross universal coupling high-speed motion, improve the working condition of whole short stress path rolling mill system, speed of production can be stabilized in higher level, and provide possibility for further improving speed of production.

Beneficial effect

The utility model structure more stably operates under high-speed motion state whole short stress path rolling mill system, has reached the effect of stable yields, and the employing of this structure simultaneously can make system further raise speed, thereby provides possibility for increasing production.

Accompanying drawing explanation

Fig. 1 is not for adopting the schematic diagram of location structure;

Fig. 2 is structural representation of the present utility model;

In figure: roll spindle nose 1, cross universal coupling roll end sleeve 2.

The specific embodiment

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

As shown in Figure 2, a kind of Novel rolling roller end location structure of the utility model embodiment, comprises roll spindle nose 1, cross universal coupling roll end sleeve 2; Described roll 1 and cross universal coupling sleeve 2 couple together closely, effectively utilize the rigidity of roll, when cross universal coupling vibrates because of high-speed motion, by roll, better limit its amplitude, thereby alleviated vibration, made whole short stress path rolling mill system more stable under high-speed motion state.

As preferably, described roll spindle nose 1 contains alignment pin.

As preferably, described cross universal coupling roll end sleeve 2 contains locating hole.

The utility model is a newly-increased alignment pin that has certain external diameter and length at original roll spindle nose 1 place as shown in Figure 1, become as in Fig. 2 with the appearance as shown in the roll spindle nose 1 of alignment pin.Simultaneously on the cross universal coupling roll end sleeve 2 shown in original Fig. 1, corresponding increase and roll alignment pin have the pin-and-hole of the certain length of accurate matching relationship, become the appearance of the cross universal coupling roll end sleeve 2 with locating hole as shown in Figure 2.Bearing pin coordinates more accurate with pin-and-hole, make roll and cross universal coupling sleeve connect into closely an integral body, effectively utilized the rigidity of roll, when cross universal coupling vibrates because of high-speed motion, roll has better limited its amplitude, thereby alleviated vibration, made whole short stress path rolling mill system more stable under high-speed motion state.

The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.

Claims (2)

1. a Novel rolling roller end location structure, comprises roll spindle nose, cross universal coupling roll end sleeve; It is characterized in that: described roll and cross universal coupling sleeve link together closely, described roll spindle nose contains alignment pin.

2. a kind of Novel rolling roller end location structure according to claim 1, is characterized in that: described cross universal coupling roll end sleeve contains locating hole.
