Abstract

The utility model provides a roller crusher with simple transmission and examination, which is characterized in that a crushing roller and a gear box are connected by a cross axle universal coupling, a bearing supporting the crushing roller and a bearing seat body can move and rotate in a sliding slot, the mandrel of the crushing roller is cut into two half-shaft ends which are lapped, an outer box is provided with a sleeve, and a supporting nut is screwed. Thus, the transmission of power is simple and reliable, and the utility model saves the box body of the counter gear, improves the smoothness of the transmission, reduces the noise, avoids the teeth breakage, protects the bearing and other components and makes the replacement and the examination of the crushing roller more convenient.

Description

Roller crusher power transmission device

The utility model relates to a kind of improved kibbler roll power transmission.

Existing kibbler roll transmission of power is continued to use the fifties Soviet Union technology substantially, promptly is meshed and realizes by long profile modified gear (3), (5).This transfer mode exists following two problems:

1. the translation distance of movable breaker roll is less than 50 millimeters, once can not protect parts not to be damaged effectively when meeting super large piece and ironware.

2. the long profile modified gear (3), (5) that are meshed are cast form, and kinematic accuracy is low in the transmission, and the noise height impacts greatly, and accidents such as broken teeth easily take place, and its structure is referring to figure one, figure two.

For solving above-mentioned two problems, U.S. Gundlach(guiding principle nanogram) company has manufactured and designed the kibbler roll shown in figure three, figure four, figure five, figure six, its transmission of power is by main-gear box (20) → stationary roll (15), (16) → auxiliary gear case (21) → driven voller (12), (14), stationary roll and driven voller are rotated in opposite directions synchronously, wherein auxiliary gear case (21) is provided with two auxiliary gear bridges, effect that move within the specific limits its difference starting power transmission and driven voller (12), (14), its displacement reaches 140 millimeters.Played overload protection preferably.

In October, 87, Zhejiang Tongxiang Coal Mining Machinery Plant and Yanzhou coal separation designing institute are with reference to mapping U.S. Gundlach(guiding principle nanogram) the disintegrating machine basis grinds and developed 4PGC-380/350 * 1000 types, four rod-toothed crushers, and its structure is seen figure three, figure four, figure five, figure six.

The purpose of this utility model is that a kind of improved kibbler roll power transmission will be provided, its can simple and reliable ground transferring power, and can play the effect of overload protection effectively.

Two effects according to kibbler roll operation principle point and reference figure (six) auxiliary gear case:

1. transferring power makes the rotation synchronously in opposite directions of every pair of breaker roll;

2. relatively move between the permission breaker roll.

The purpose of this utility model is achieved in that

1. the output shaft of gear-box (47) arrives breaker roll (40), (42), (43), (44) by cross-axle universal shaft shaft coupling (48) with transmission of power respectively, its cross-axle universal shaft shaft coupling (48) middle part is telescopic splined shaft and cover socket, but the distance that compensating axial extends when roller relatively moves;

2. each roll centre axle (41) links by subdivision semiaxis (52) and sleeve (53).It can transmit moment of torsion, bears moment of flexure, scalable again certain-length (referring to figure ten, figure 11);

3. bearing seat (50) is designed to come and go in chute (49) and moves, and is rotatable again, and it can be followed breaker roll automatically and together move and rotate (referring to figure nine, figure ten);

The novel concrete structure of this reality is provided by following embodiment and accompanying drawing thereof.

Figure seven, figure eight always scheme for the utility model.

Figure nine, figure ten, figure 11 are the utility model bearing body figure.

Figure 12 is the utility model gear-box figure (sequence number 47).

Describe the details and the working condition of the concrete device that the utility model proposes in detail below in conjunction with figure seven, figure eight, figure nine, figure ten, figure 11, figure 12.

The power of motor (46) is delivered to gear-box (47) by V-belt (45), and driving gear in the casing (55), (59) are meshed with driven gear (58), (61), makes the rotation synchronously in opposite directions of a pair of breaker roll.

In the course of the work; relatively rotate breaker roll one end enter bulk can not be broken during object; required crushing force is greater than the protection initial tension of spring; so broken clearance between roll will increase; at this moment; cross axle is shaft coupling (48) and breaker roll axle (41) the one very much, extend; two want the deflection certain angle; bearing seat (50) slides and deflection in chute (49); protected bearing and parts not to be damaged; after this material falls down, come back to normal operation position under the thrust effect of the spring at breaker roll two ends (39).

At the breaker roll odontotripsis or fracture when need changing, only nut (54) pine that holds out against on the subdivision semiaxis (52) is gone, sleeve (53) is dialled to the bearing side, breaker roll can be hung out casing together with axle, make maintenance and change very conveniently, body need not disintegrate, and does not also dismantle bearing.
