Problems solved by technology

[0003] The main part of the road roller for rolling the soil and the road surface is the drum. When the drum is assembled, a certain gap is reserved between the panel and the drum to ensure good rotatability. However, during the rotation of the drum, the imbalance of the road surface will cause the drum to generate axial force. , causing its axial movement or inclination, causing the roller to slide on the shaft body, and the inclination of the roller may also crush the panel

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 and figure 2 As shown, the present invention includes a drum 2 and a shaft body 14 axially penetrating the drum 2. The drum 2 can rotate around the shaft body 14, and the two ends of the shaft body 14 are respectively fixed on two panels 12 fixedly connected with the road roller body. A balance clamping device is respectively connected between the two ends of the panel 12 and the drum 2. The balance clamping device includes a roller 6 whose axis is parallel to any radius on the end surface of the drum 2. face tangent.

[0016] On both ends of the drum 2 there are rollers 6 that are tangent to it, and the drum 2 is clamped by the rollers 6, because there is a line contact between the rollers 2 and the rollers 6, so the rollers 6 will not hinder the The rolling of drum 2. However, it should be noted that the placement direction of t...

Abstract

The invention discloses a novel road roller drum assembly which comprises a drum (2) and a shaft body (14) which axially penetrates through the drum (2), wherein the drum (2) rotates around the shaft body (14); the two ends of the shaft body (14) are respectively fixed on two panels (12) of a road roller body. The novel road roller drum assembly is characterized in that balance clamping devices are respectively connected between the two panels (12) and the two ends of the drum (2); each balance clamping device comprises a pin roller (6) the axis of which is parallel to any radius of the end surface of the drum (2); the circumference surface of each pin roller (6) is tangent to the end surface of the drum (2). According to the invention, the pin rollers (6) which are tangent to the end surfaces of the drum (2) are arranged on the end surfaces of the drum (2), the drum (2) is clamped through the pin rollers (6), and the rolling of the drum (2) is obstructed due to linear connection of the rum (2) and the pin rollers (6).

Description

technical field [0001] The present invention relates to components on a road roller, in particular a road roller drum assembly. Background technique [0002] Road rollers belong to the category of road equipment in construction machinery. They are widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-cohesive and cohesive soils, Subgrade stabilized soil and asphalt concrete pavement layer. [0003] The main part of the road roller for rolling the soil and the road surface is the drum. When the drum is assembled, a certain gap is reserved between the panel and the drum to ensure good rotatability. However, during the rotation of the drum, the imbalance of the road surface will cause the drum to generate axial force. , causing its axial movement or inclination, causing the roller to slide on the shaft body, and the inclination of the roller ...
