Refrigerant compressor having a connecting rod with a force application point at crank pin which is displaced in a direction of the bearing in relation to the axial center of the crank pin
Abstract:
The invention concerns a refrigerant compressor (1), in particular a semi-hermetic refrigerant compressor, with a compressor block (5) comprising several cylinders arranged in a star shape, a motor, whose rotor is unrotatably connected to a crankshaft (11) that comprises a crank pin (22) and is supported in a bearing (13) in the compressor block (5), and a piston in each cylinder, each piston being connected via a connecting rod (23) to the crank pin (22), the connecting rod (23) comprising a bearing pad (24) that rests on the crank pin (22), the bearing pads (24) of all connecting rods (23) being held on the crank pin (22) by means of a ring arrangement (25). It is endeavored to keep the load on the crankshaft small. For this purpose, each connecting rod (23) has a power application point (49) at the crank pin (22), which is displaced in the direction of the bearing (13) in relation to the axial center of the crank pin (22).
Abstract(Chinese):

本发明涉及一种制冷剂压缩机（1），特别是一种具有压缩机组件（5）的制冷剂压缩机（特别是半封闭式制冷剂压缩机），该压缩机组件包括若干个以星形排列的气缸，其转子不可旋转地连接到曲轴（11） 包括曲柄销（22）并被支撑在压缩机组件（5）中的轴承（13）中，以及每个气缸中的活塞，每个活塞经由连杆（23）连接到曲柄销（22）， 所述连杆（23）包括支撑在所述曲柄销（22）上的轴承瓦块（24），所有连杆（23）的轴承瓦块（24）通过环形件保持在曲柄销（22）上 安排（25）。 努力保持曲轴上的载荷很小。 为此，每个连杆（23）在曲柄销（22）处具有相对于曲柄销（22）的轴向中心沿着轴承（13）的方向移动的动力施加点（49） ）。
