Abstract

A weigh module (100) comprises a load cell (4), a supporting member (1) and a load transmitting arrangement (2). The supporting member (1) comprises a receiving hole (13) extending vertically and thoroughly. The load transmitting arrangement (2) comprises a connecting member (23), a bearing member (21) and a rolling ball (22). The connecting member (23) connects the load cell (4) to the supporting member (1). One end of the connecting member (23) is fixed to the load cell (4) and another end of the connecting member (23) extends into the receiving hole (13). The bearing member (21) is disposed in the receiving hole (13) and is fixed to the supporting member (1). The rolling ball (22) is disposed between the bearing member (21) and the connecting member (23), whereby the force applied on the supporting member (1) can be transferred to the load cell (4) via the bearing member (21), the rolling ball (22) and the connecting member (23).

Dependent claims

A weigh module, comprising:

a load cell;
a supporting member comprising a receiving hole that extends vertically and through the supporting member, the receiving hole comprising a first receiving space and a second receiving space that is connected to the first receiving space;
and
a load transmitting arrangement, comprising:
a connecting member that connects the load cell to the supporting member, the connecting member comprising a fixed end fixed to the load cell, a limiting end that extends into the second receiving space, and a connecting part that connects the limiting end to the fixing end, the limiting end configured to prevent the supporting member from being lifted off of the connecting member in the vertical direction;
a bearing member disposed in the receiving hole and fixed to the supporting member;
and
a rolling ball disposed between the bearing member and the connecting member, whereby the force in the vertical direction applied on the supporting member can be transferred to the load cell via the bearing member, rolling ball and the connecting member.
